TECHNICAL RENEWAL OF THE ENTERPRISE

(STI-MiR-008-07)

1. Basic principles

development of enterprise technical re-equipment programs.

Enterprise technical re-equipment program (“CCI Program”) it is advisable to consider as an integral part of the Program more high level. We will call it henceforth “Product Release Program” or “PVI”.

The development and implementation of the PVI can be financed by:

government agencies; in this case, we will call the PVI “Government Order”. commercial structures performing the functions of the Customer and taking on the risks associated with the subsequent sale of products; in this case, we will call the PVI “Commercial order”. the enterprise itself; in this case, the enterprise develops a PVI, guided by its views on the prospects for selling products released in accordance with the PVI on the market; in this case, the enterprise assumes the risks associated with the sale of products; PVI is financed from the enterprise’s own funds with the possible use of others (attracting loans, investors, etc.); in this case, we will call the PVI “Enterprise Order”.

Regardless of the nature of the Customer (government agency, commercial structure, the enterprise itself), when developing PVI, it is advisable to proceed from the following premises:

1.1. The Customer and source of financing for the development and implementation of PVI have been determined;

1.2. The implementation of PVI will be carried out in a market economy, which presupposes:

performance of works and services at market prices; the presence of competition (adversarialism) between potential performers of individual works.

1.3. The PVI program should be subject-specific in nature. This will allow the allocated funds to be concentrated on ensuring the effective functioning of key (for the production of a specific product) technological chains, without dealing with the problem of renovating the existing fleet of technological equipment as a whole.

1.4. To restore the lost personnel potential of the enterprise (attracting specialists who left the enterprise, pensioners, young specialists), it will be necessary to create competitive (compared to other types of activities) wage conditions; organization of training for machine operators and repairmen to work on CNC machines, maintenance and repair of this equipment.

1.5. The technical level and quality of the Product and its elements developed and produced within the framework of the PVI must be determined by standards and other regulatory and technical documents mandatory for execution within the framework of the PVI.

1.6. The implementation of PVI should be provided with targeted financing in amounts determined taking into account real market conditions.

2. Main stages of development of the Chamber of Commerce and Industry Program

The purpose of technical re-equipment of the enterprise in general case can be considered ensuring the transition of an operating enterprise to the production of a new product (“Product”) without stopping production. In this case, the product must meet the requirements of competitiveness (in terms of technical characteristics, workmanship, after-sales service, price).

The development of a technical re-equipment program for an enterprise (“CCI Program”) may include the implementation of individual stages.

Some of the stages may have already been completed at the time the development of the Chamber of Commerce and Industry Program begins. This will speed up the development of the CCI Program.

It is possible to outline the main stages (blocks) of the development of the Chamber of Commerce and Industry Program.

2.1. Determination of production volumes of Products in pieces by year.

2.2. Development of performance characteristics (TTC) of the product and its elements (components).

2.3. Determination of the acceptable market value of the Product (RSA) The basis for this can be taken as the market value of the product - an analogue, domestic or foreign (RSA), determined in accordance with the technical specifications of the Product.

2.4. Clarification of production volumes, timing, taking into account the amount of allocated (planned) funds and the market value of the Product.

2.5. Determination of the market value of components (RSCI).

The relative cost of components in the price of previously produced Products can be taken as a basis. In necessary cases (the Product has no predecessors), the RSCI can be determined by expert means, based on the RSCI.

2.6.Updating (revision) of standards, technical specifications (TS) and other regulatory and technical documentation that will be used for the release of the Product, taking into account the developed performance characteristics.

2.7. Bringing technical documentation for the Product into compliance with revised standards and specifications.

2.8. Identification for each Product of enterprises that can perform the functions of related suppliers (supply of materials and components).

The existing cooperation between the enterprise can be taken as a basis.

2.9. Allocation in the enterprise equipment park, equipment necessary for the implementation of the Product Release Program (PVI park).

2.10. Conducting a prompt assessment of the technical condition of the PVI fleet.

2.11. Determination of “bottlenecks” in the PVI fleet from the point of view of ensuring the required quality of manufacturing of parts and assemblies in accordance with the requirements of regulatory and technical documentation, taking into account the actual technical condition of the equipment.

2.12. Determination of “bottlenecks” in the PVI fleet from the point of view of the total labor intensity of the Product, while maintaining the output of the products manufactured by the enterprise along with the release of the Product during the transition period.

2.13. Development of proposals for “debottlenecking” in the PVI fleet in terms of workmanship and labor intensity (major repairs, modernization, equipment purchase).

2.14. Development of a draft Chamber of Commerce and Industry Program based on clause 2.13.

2.15. Determination of the total costs for the implementation of the CCI Program project.

2.15. Determination of the total costs for the implementation of the PVI Program (taking into account the costs of technical re-equipment, costs in the production sector).

2.16. Clarification of the PVI and Chamber of Commerce and Industry Programs, taking into account financing opportunities and achieving a competitive price for the Product.

2.17.Development of a scheme for financing work within the framework of the VVI and CCI Programs.

2.18. Approval of the final version of the CCI Program.

2.19.Implementation of the CCI Program with the involvement, if necessary, of third-party organizations..

Notes.

1.The order of performing the steps may differ from that given earlier. Many steps can be performed in parallel.

2. The results of the work completed before the start of the development of the Chamber of Commerce and Industry Program require clarification.

TECHNICAL RENEWAL

MUP "FOOD PLANT"

FOR 2004 – 2007

Program Passport

Introduction

The technical re-equipment program of the municipal unitary enterprise "Food Plant" for 2004 - 2007 (hereinafter referred to as the Program) was developed in accordance with the decision of the meeting on the reconstruction of the ammonia refrigeration plant and the construction of block boiler houses for steam supply (minutes dated April 16, 2003, approved by the First Deputy Head of the Administration V. Yunakov). P.)

The need to develop the Program is determined by the requirements of the current legislation of the Russian Federation in the field of industrial safety, as well as the requirements of regulatory and guidance documents of the State Mining and Technical Supervision of Russia on ensuring the industrial safety of hazardous production facilities.

The implementation of the main program activities is currently impossible without taking support measures from the City Administration.

1. Contents of the problem and justification for the need to solve it using software methods
The municipal unitary enterprise "Food Plant" is one of the enterprises whose normal functioning and uninterrupted production of products, in particular bread and bakery products, has a significant impact on maintaining the stability of the social climate in the city. One of the factors for the sustainable operation of the enterprise is the uninterrupted supply of refrigeration to the following industries: bakery production (storage chambers for raw materials), confectionery production (storage chambers for raw materials and finished products), ice cream production (storage chambers for raw materials, finished products, technological equipment), kvass production (cooling and storage of the finished product).

Since 1981, the Food Processing Plant has been operating centralized system refrigeration, the main part of which is the ammonia refrigeration unit (ARU). Until 1999, the operation of ACS was regulated by the “Rules for the Design and safe operation ammonia refrigeration units”, the operation of ACS was not a licensed activity, and ACS equipment was not supervised by the local body of Gosgortekhnadzor.

In 1998-1999 new " General rules explosion safety for fire and explosion hazardous chemical, petrochemical and oil refining industries" (approved by Decree of the Gosgortekhnadzor of Russia dated December 22, 1997 No. 52) and "Rules for the design and safe operation of ammonia refrigeration units" (approved by Decree of the Gosgortekhnadzor of Russia dated June 30, 1998 No. 38).

In accordance with the requirements of the new rules, along with periodic testing of ACS vessels and pipelines, after 20 years of their operation, it is necessary to carry out technical diagnostics using ultrasonic and color flaw detection and the acoustic emission method, as well as diagnostics of compressors. In case of positive diagnostic results, permission to operate is given for a period of no more than 4 years. It is allowed to diagnose each piece of equipment only twice. After the expiration of the 4-year period from the moment of secondary diagnosis, the equipment is subject to mandatory replacement. Thus, the food processing plant equipment must be replaced no later than 2007, because The initial diagnosis of most of the equipment was carried out in 1999.

In addition, the ammonia refrigeration unit currently in operation at the food processing plant does not meet the requirements of the new “Rules...” in such serious parameters as safety automation, constant automated control of the concentration of ammonia in the air, and the existing building structures of the ACS building also do not meet the requirements of the new rules.

In the current situation, the question naturally arose about reconstructing the food processing plant's food processing plant to bring it into compliance with the requirements of new regulatory documents.

Commissioned by the UKS of the City Administration in 2000 – 2001. The specialized organization CJSC Tekhagropromservice (Moscow) developed a project for the reconstruction of the ACS. The estimated cost of the work as of the beginning of 2001 was about 13 million rubles. It should be noted that this project did not provide for the replacement of the technological equipment of the ice cream shop, which has been in operation without updating since the 50s of the last century.

Constant supervision over the operating conditions of the food processing plant's food processing plant is carried out by RGTI-16. Clause 2 of the act-instruction of RGTI-16 dated November 16, 2001 No. 74 established the deadline for the withdrawal of the ACS for reconstruction - no later than 01/01/2002. An article was included in the draft city budget for 2002 about the beginning of financing of reconstruction work, but when the budget was approved, this article was excluded.

During the next inspection in March 2002, inspectors from RGTI-16 and Rostrudinspektsiya stopped operation of refrigerator No. 1 (instruction No. 1/03 dated March 27, 2002). The refrigeration supply to refrigerator No. 1 has been discontinued since May 1, 2002.

01/29/2003, Deputy Head of RGTI-16 R.V. Pomelov. “Instruction No. 1/2 for the suspension of work (facility)” was issued, according to which it is necessary to stop the operation of the agricultural management unit of the municipal unitary enterprise “Food Plant” from January 30, 2003. If this instruction is strictly followed, the following are subject to stoppage: bakery production, confectionery production, ice cream shop, as well as It is impossible to produce kvass in the summer. As a result of this, 138 people (55% of the enterprise's payroll) are simultaneously left without work, and the very existence of the food processing plant is called into question.

A similar situation is possible in the case of the implementation of a project for the reconstruction of an agricultural facility, because Complete replacement of equipment, pipelines, changes in building structures are not possible without taking the installation out of operation for a long period.

In these conditions, it is obvious that there is a need to develop a Technical Re-equipment Program for the Municipal Unitary Enterprise “Food Processing Plant”, which provides an alternative to the existing option for reconstructing the entire refrigeration supply system of food processing plant production, namely: a gradual transition to autonomous refrigeration supply using a safer refrigerant – freon.

2. Main goals, objectives and deadlines for the implementation of the Program
The main goal of the Program is to develop and implement an alternative option for reconstructing the refrigeration supply system of a food processing plant with a phased transition to an autonomous supply of cold to the enterprise's production using a safer refrigerant, compared to ammonia, - freon.
The implementation of the Program will allow solving the following tasks:

• 
  Bringing the refrigeration system of the municipal unitary enterprise "Food Plant" into compliance with the requirements of the legislation of the Russian Federation in the field of industrial safety.
• 
  Liquidation of a chemically hazardous production facility in a residential part of the city. Reducing the risk of man-made emergencies through the use of freon instead of ammonia in refrigeration equipment. (The existing ACS contains 10 tons of ammonia).
• 
  Phased reconstruction of the refrigeration system, which eliminates the need for long production stops and forced downtime.
• 
  A radical renewal of the ice cream shop's equipment fleet, in contrast to the existing version of the reconstruction of the agricultural plant, where this was not provided for.

Duration of the Program implementation: 2004 – 2007.

1. 
   Activities to implement the Program

To implement the Program, a set of measures is provided to allow:

• 
  ensure compliance with the requirements of regulatory documents regulating such work;
• 
  avoid long production stops during reconstruction, and, therefore, do not reduce the volume of output and do not worsen the financial and economic performance of the enterprise;
• 
  ensure stable and planned funding for each event.

1. 
   Resource support for the Program

The most important condition for the implementation of the Program is stable financing of each stage.

Financial support for the Program will be provided from the following funds:

• 
  city ​​budget;
• 
  own funds of the Municipal Unitary Enterprise "Food Plant".

The phased implementation of the Program will make it possible to calculate in advance the amount of funding for each stage, determine the share of funding for each source, specifically, at each stage of implementation. This will also make it possible to make proposals for the inclusion of relevant expenditure items in the city budget for the corresponding financial year in a planned manner.

The amount of costs for the implementation of the Program is approximately determined at 15.3 million rubles, of which: enterprise funds - 1.0 million rubles, budget funds - 14.3 million rubles.

The final amount of financial investments for the implementation of the Program as a whole and for each activity separately will be determined after the implementation of activity No. 1, i.e. after completion of the development of design and estimate documentation.

1. 
   Implementation mechanisms and monitoring the progress of the Program

The mechanisms for implementing the Program and monitoring the progress of its implementation are based on existing system administrative and economic subordination of municipal enterprises to the city Administration, as well as on the existing pattern of interaction between the city Administration and the Duma.

The customer of the Program is the City Administration. The main investor of the Program is the Management Department with the participation of the Municipal Unitary Enterprise "Food Plant". The Program executor is determined based on the results of a competition in accordance with the current rules for the distribution of municipal orders.

Monitoring the progress of the Program implementation is carried out by:

• 
  City Administration;
• 
  Duma of Sarov;
• 
  management of the Municipal Unitary Enterprise "Food Plant";
• 
  Regional Mining Technical Inspectorate (RGTI-16).

Financial control is carried out in accordance with the established procedure by the city finance department.

Current management of the implementation of the Program at each stage is carried out by the Municipal Unitary Enterprise "Food Plant".

1. 
   Socio-economic efficiency of the Program

The implementation of the Program in full will ensure the conditions for the sustainable and safe functioning of the refrigeration supply system of the food processing plant and the entire enterprise as a whole. The use of new equipment and technologies in the production of ice cream will allow existing rigid competition to expand the range, maintain, and in the future increase the volume of products. The risk of man-made emergencies during operation is minimized new system cold supply, the consequences of which could affect some of the houses in the nearby residential area. Further stable work all industries that use cold: bakery, confectionery, ice cream and kvass production, which will allow not to reduce the volume of production of food products, which are in constant strong demand among city residents.

All of the above results of the Program implementation will contribute to further maintaining the stability of the social climate in the city of Sarov.

Economic efficiency from the implementation of the Program is determined by a significant reduction in operating costs during implementation autonomous system refrigeration using freon, namely:

• 
  a significant reduction, by 2 - 2.5 times, in the energy intensity of refrigeration equipment;
• 
  reducing water consumption when producing cold;
• 
  reduction in the number of service personnel, reduction in wage costs;
• 
  reducing the range and cost of consumables, repair materials and spare parts;
• 
  reduction of payments to the environmental fund for the release of HCPs into the atmosphere.

For the long-term competitive development of any machine-building enterprise, it is necessary to create not only unique equipment, but also to be successful among the leading companies in its industry. The competitiveness of an enterprise depends on how the technical process proceeds at it, and its organization directly depends on the quality of the equipment used. That is why all industrial companies pay special attention to the implementation of complex projects for the purchase of modern high-tech equipment. The equipment and technical weapons bureau is engaged in updating the machine fleet at OJSC AMZ (Arzamas Machine-Building Plant). The head of the bureau, Oleg Vlasov, shared with us about the state of current affairs at the enterprise and immediate plans in the field of technical re-equipment.

- Oleg Evgenievich, what work on technical re-equipment has already been carried out at the enterprise this year?

As part of the investment program of the military-industrial complex for 2014 in the field of technical re-equipment of AMZ OJSC, it was planned to purchase new efficient equipment. This year, we have already purchased a band saw for the procurement area, which allows us to speed up the process of creating products while maintaining high accuracy. Also a machine for laser cutting of metal, it already operates in an automatic press shop. We have had similar equipment at MSC-8 for several years now. The motivation for purchasing a laser for PAC was the price of expensive dies for presses. In order not to wait for the production and repair of the necessary dies, it was decided to purchase and install laser equipment in this workshop. Training was also carried out for two service technicians who are now successfully working there.

To manufacture the headlight-spotlight product, which is installed on the Tiger armored car, a CNC turning and processing center was purchased. It will arrive at the plant at the end of October.

A plotter was purchased for cutting rubber gaskets. At MSC-2 there was a problem associated with cutting rubber products: before that, the site used a low-power laser purchased 5 years ago, which was beyond the capabilities of today’s labor-intensive production rhythm. We spent a long time selecting equipment that could effectively cope with this task. And now the activity of the site has intensified significantly.

Currently, MSC-4 is carrying out commissioning work on a horizontal milling machining center, which will be used to produce levers intended for assembling new promising models of armored vehicles. The business partner was the Moscow company Soldream, which is one of the large suppliers of industrial equipment in Russia.

- How is the decision to purchase equipment made and how does this process proceed?

The technology department is considering the launch of new products in mass production, finds out what equipment needs to be purchased for this. A technological chain is built, a list of machines is formed and the feasibility of their purchase is determined. After this, technical specifications are drawn up and work is carried out with potential suppliers. As a rule, offers come from about 15 companies. The technical directorate selects the most acceptable and suitable manufacturers for the plant in accordance with the quality and pricing policy. In custody in open mode A tender is held, to which managers and technical specialists of supplier companies come, where they present their equipment and answer questions that interest us. After this, the tender committee of the enterprise decides to purchase the most suitable samples. The final point is the statement decision taken tender committee of LLC "VPK" and signing an agreement with the supplier company.

- How to choose the right equipment and not make a mistake?

When choosing purchased equipment, some suppliers are ready to provide their equipment to the enterprise completely free of charge for the purpose of direct operation on the production site and subsequent decision-making on its purchase. We took advantage of one of these opportunities: a turning and machining center was delivered to the plant for test use. Within a month, the equipment will be actively operated by MSC-8 employees to determine its quality characteristics and production capabilities.

- How does purchasing new equipment help solve problems in production?

We purchase new high-tech equipment, which reduces the time required to manufacture products and increases their quality. In a word, new equipment must fulfill the tasks facing the enterprise today.

The implementation of technical re-equipment projects allows you to expand production prospects, speed up production, increase efficiency and gain new opportunities. There is no doubt that investing in new technologies is worthwhile. The plant is developing dynamically, orders are being received, contracts are being signed, and production volumes are growing accordingly. In order to carry them out in a timely manner and with high quality, today it is simply necessary to update the machine park. After all, one CNC machine can easily replace several old ones at once, close the shortage of qualified personnel, as well as free up space and improve production standards.

- How do plant personnel cope with working on new modern equipment?

Along with the purchase of a new machine, personnel training is carried out. We purchase high-tech equipment, which requires true professionals to operate. The company has specialists who have received initial basic knowledge work with CNC machines in schools and technical schools. And this is quite a significant factor. For example, laser equipment has been operating at MSC-8 for about 5 years. When purchasing a laser from the PAC, specialists from workshop eight took part in training operators and observed the operation of the new machine. When purchasing more narrowly specific equipment, specialists undergo mandatory training from outside service department supplier company.

It is also worth noting that modern and high-tech equipment requires special care to maintain its precise capabilities, namely, it is necessary to regularly clean it, wipe it, carry out autonomous maintenance, and observe production standards. The plant administration has repeatedly noted cases of neglect of these rules by workers and foremen of some workshops, in particular MSC-1 and MSC-8, and raised these issues for discussion. Is it worth purchasing expensive equipment and not following the basic rules of caring for it? I think everyone knows the answer! Therefore, in addition to training personnel to work on new machines, it is also necessary to instill skills in their maintenance after operation, and foremen and shop managers must strictly monitor this.

- What are your plans for technical re-equipment of the plant for the near future?

IN this moment The supplier of turning equipment is determined. The plant plans to purchase 12 units of CNC lathes at the end of 2014 - beginning of 2015. This high-tech equipment will maximize the quality of manufactured products and solve the problem of shortage of turners.

Based on the analysis of the technical condition of the enterprise's fixed assets, taking into account its actual, moral and physical wear and tear, and balance sheet data, the enterprise has developed detailed program re-equipment and renewal of production for 2012 and subsequent periods until 2015. The need for the necessary funds has been calculated.

The action plan for the development of investment activities of JSC “Novopolotskzhelezobeton” in 2012 is as follows:

1. Construction of a mini-CHP with the installation of an energy source for the combined production of electricity and heat (a business plan for the investment project has been developed).

The main idea of ​​the investment project

Due to the fact that JSC “Novopolotskzhelezobeton” at the stage of its formation was part of Trust No. 16, the power supply scheme was built and developed as a single electric power complex.

Currently, the power supply scheme for the entire industrial zone, gravitating towards Novopolotsk Zhelezobeton OJSC, consists of:

Main step-down substation (GPP) 110/35/6KV, which is on the balance sheet of Novopolotskzhelezobeton OJSC;

29 transformer substations 6/0.4 KV with a unit capacity from 160 to 1000 KVA, which are both on the balance sheet of JSC Novopolotskzhelezobeton enterprise and on the balance sheet of other enterprises;

High voltage cable lines.

The power supply system for transformer substations is a ring circuit that provides the necessary reliability (redundancy) of the 6KV power network. To limit short circuit currents in ring circuits, there are breaks at TP 6/0.4 and part of the KL-6KL are in “hot” reserve.

The scheme has 2 powerful distribution points (centers) RP-30, RU 6KV substation “Promploshchadka” with all types of protection installed: overcurrent protection, current cut-off, “earth protection”,

Heat supply to Novopolotskzhelezobeton OJSC is carried out by two types of coolant: steam and district heating water.

Steam heating carried out from the Novopolotsk CHPP through the networks of JSC "Polymir" by double steam reduction:

The total length of the steam lines is:

ü DN 400 – 1841m;

ü DN 300 – 400m;

ü DN 350 – 70M.

As a result of long-term operation, the thermal insulation of steam pipelines has largely lost its heat-insulating properties, and the loss of steam thermal energy has sharply increased.

Heat supply with district heating water For heating needs, it is carried out from the heating route “CHPP-8th microdistrict of the city”.

The total length of the pipelines is:

ü DN 300 – 160m;

ü DN 250 – 1398m;

ü DN 200 – 800M

As a result of long-term operation, the thermal insulation of heating water pipelines has also largely lost its thermal insulation properties, and thus, the loss of thermal energy of heating water has sharply increased.

During the implementation of this investment project, it is planned to build a mini-CHP on the existing production facilities of Novopolotskzhelezobeton OJSC, which will lead to a change in the existing electricity and heat supply of the enterprise.

Fundamental technological solutions

This project provides for the creation of an energy technology complex consisting of one microturbine power unit with an electric power of 600 kW, four Viessmann Vitomax 200HS steam boilers, three of which have a capacity of 2.9 and one of 5 tons of steam per hour, as well as a back-pressure steam turbine with an electric power of 180 kW and other auxiliary equipment to ensure the functioning of the energy complex. The quality of water sent for steam production is ensured by a water treatment station (15 m 3 /hour) and a feed deaeration unit (15 m 3 /hour). Energy production at the mini-CHP is planned to be carried out automatically. The complex is connected to existing communications, which are located at a short distance from the energy complex; the final choice of connection points to communications is determined by the project.

The steam boiler house is located on the freed-up area of ​​the existing compressor building, which has a free building volume of 18x18x10.8 m for installation of boiler equipment.

The internal volume of the boiler room houses four steam boilers with auxiliary equipment, chemical water treatment equipment and a group of pumps. On the second tier of the room there is an operator's room, a gas distribution unit (GDU), heat exchange equipment, a feedwater tank and a deaerator. In the room adjacent to the boiler room there is a turbine room, where a steam turbine with an electric generator is located. A C600 INDKG power unit based on three microturbines in a container design and a chimney are installed outside the building.

The preliminary layout of the first tier of the mini-CHP is shown.

The area of ​​the room allows the installation of boilers without violating the requirements of the “Rules for the design and safe operation of steam and hot water boilers. Unitary Enterprise "DIEKOS", 2007." When installing boilers, the distance between the boilers and the wall of the boiler room is more than 1.5 meters, which corresponds to the above rules. The final layout of the energy complex will be determined by the project.

Four steam boilers of the Vitomax 200-HS type from Viessmann are designed to generate thermal energy using gaseous fuel. A low level of emissions of harmful substances is ensured by a three-pass scheme of gas ducts of the boiler block with a low thermal intensity of the combustion chamber.

– Preliminary planning of the first tier of a mini-CHP

The main technical characteristics of the steam boilers planned for installation in the boiler room are given.

Specifications steam boiler Vitomax 200-HS

The cogeneration power plant is designed to cover the enterprise's basic electricity consumption schedule, as well as to supply the production of hollow core slabs (Tensiland line) and the domestic needs of Novopolotskzhelezobeton OJSC with thermal energy in the form of hot water.

The power plant is a power unit consisting of three microturbine generators with an electrical power of 200 kW each and a heat recovery boiler.

The power unit model “C600 INDKG” from CAPSTONE (USA) is made in a container design and is located in close proximity to the boiler room. The thermal circuits of the power unit and boiler house are combined into a single thermal circuit, where they complement each other.

Technical characteristics of the power unit model “C600 INDKG” are presented.

Technical characteristics of the power unit model “C600 INDKG” from CAPSTONE (USA)

The TGU R-0.8-1.7/0.7 turbogenerator unit is designed to generate electricity by using the potential of steam. The steam turbine is made in a single-cylinder design on a common foundation frame with a generator. The turbine is designed for continuous continuous operation of at least 8000 hours per year. The range of turbine power changes is from 0 to 110% of the nominal value. TGU is manufactured according to TU VU 191297032.001-2010 “Low-power energy-saving turbines. Technical conditions". The manufacturer of the TGU R-0.18-1.7/0.7 turbogenerator unit is the United Energy Company (Republic of Belarus).

Technical characteristics of the TGU turbogenerator unit
P-0.18-1.7/0.7 are presented in Table 5.3.

Technical characteristics of the turbogenerator unit TGU R-0.18-1.7/0.7

Fresh steam from boilers with a pressure of 18 bar in the amount of 8 tons per hour enters the turbogenerator through a common manifold. The above volume of steam at a temperature of 230°C ensures the operation of the steam turbine at the maximum possible load. Electricity generation by TGUs is carried out depending on the steam consumption by consumers. During operation of the turbogenerator unit, its expected load will be 83.87% of the nominal value.

Steam exhausted in the turbogenerator at a pressure of 7 bar is sent for technological needs. The steam pressure of 7 bar is determined based on the plant's efficiency requirements, taking into account the pressure drop during its transport. Also, the reconstruction of the on-site steam network planned for JSC Novopolotskzhelezobeton will allow the delivery of steam at a pressure of 7 bar through a smaller cross-section of the steam pipeline, which reduces capital investments in the reconstruction of the steam network, and by reducing the contact area of ​​the steam, it reduces thermal transport losses through the pipeline wall.
