STEAM BOILER - Домашняя

1 STEAM BOILERHigh potential of the Group of Companies JSC Machine-Building Plant ZiO-Podolsk and JSC Engineering Company ZIOMAR enables them today to carry out a wide range of activities in the field of power machine-building. The leader of Russian industry Machine-Building Plant ZiO-Podolsk (ZiO) traces its history back to the year is an industrial-engineering base for manufacturing of high-technology, competitive heat exchange equipment. Modern methods of production management and organization, as well as well-qualified personnel provide high quality and reliability of the manufactured equipment.

2 EC ZIOMAR employees perform complex research and development activities, equipment adjusting and examination of installations in operation for the purpose of their reconstruction and modernization. Our customers are the largest generating and heat-and-power will be glad if our acquaintance grows into a constructive and fruitful cooperation!SPECIALIZATIONMain products for thermal power plants are boilers for power units with the capacity of 50-800 MW firing diverse fuels, designed on the basis of advanced engineering solutions.

3 More than 700 BOILER units with various capacity and parameters have been produced for 152 domestic and foreign power plants with the total capacity of more than 66 GW, including over 16 GW for export. The Enterprise has more than 70 years of experience in design and fabrication of boilers and other thermotechnical equipment for thermal power industry. Boilers produced under ZiO trademark are operated at power plants in 20 countries such as Russia, Poland, Romania, Kazakhstan, Ukraine, Bulgaria, Vietnam, Yugoslavia, Croatia, Macedonia, Greece, China and others.

4 By agreement with the General Supplier or directly with the Customer the complete delivery of the BOILER island, additionally to the BOILER proper, can include the following: sootblowing equipment; fuel supplying, coal grinding and coal-pulverizing equipment; draft equipment and turbo air blowers; air preheaters with piping and valves; ash-cleaning equipment including electrostatic precipitators; steel structures of BOILER island and stack; pulverized coal, gas and air lines complete with valves and expansion joints; power plant pipelines; single-turn actuators and their connections; other power equipment.

5 Boilers are supplied in modular units to facilitate and speed up their erection. Export boilers are fabricated in compliance with individual Customers technical assignments. The production is based on the high level of process procedure automation and mechanization. At the present time a considerable part of power generating systems do not comply with up-to-date environmental, safety, efficiency and cyclic load capability requirements. The most practical way out is to modernize main power plant equipment.

6 In such a case the required effect can be achieved with reduced material expenses, which is very important under modern economic conditions. ZiO-Podolsk and EC ZIOMAR group of companies is paying greater attention to these issues, and it can propose a complex of original engineering solutions aimed at the modernization of the BOILER equipment that was supplied earlier to power engineers of Russia and CIS countries. The enterprise has developed and implemented engineering solutions aimed the extension of service life, producing of extra power with minimum expenses, improving of environmental performances and energy saving.

7 We propose a complex of original engineering solutions aimed at solving of the below mentioned problems and required for the modernization of the BOILER equipment that was supplied earlier: extension of the unit load control range (extension of the stable operation threshold); BOILER switchover to non-standard types of fuel; organization of nonslagging operation due to low temperature and stage-by-stage fuel combustion; improvement of fuel ignition stability and extension of the operating range without lighting; improvement of technical and economic indexes due to implementing of up-to-date engineering and design solutions; improvement of environmental performances and their brining to standard values.

8 The armory of the Special Design Bureau of BOILER Manufacture of EC ZIOMAR includes a range of engineering and process design solutions aimed at the burning process optimization and NOx level reduction to standard values without using special catalytic reactors: burning process organization with the supply of high-concentration pulverized coal; 4 SPECIALIZATION new designs of low emission burner units; stage-by-stage fuel combustion from the furance top to bottom and in a horizontal plane of each burner row; 3-stage fuel combustion with the use of reburning system; use of downdraft nozzles; use of telescopic pulverized coal dividers and special pulverized coal concentrators; high air heating application of low temperature tornado technology; NOx selective noncatalytic reduction.

9 BOILER thermal and hydraulic circuits that allow sliding pressure operation are improved in order to ensure maximum BOILER efficiency. The introduction of units with increased efficiency in compliance with the original engineering solutions of the plant is also a promising direction. The company prepared technical proposals for ultra supercritical STEAM parameter coal-fired boilers for 660 MW units as well as proposals for the modernization of coal-fired boilers of operating power units with the capacity of 300 MW.

10 In order to satisfy the needs of industrial power production and public utilities the company constructed advanced tower type gas-and-oil-fired hot water boilers with the thermal output of 70 and 120 Gcal/h that provide an opportunity for their installation in the compartments of ПТВМ hot water boilers that are out of date from moral and physical standpoint. ZiO fabricates a wide range of equipment for thermal power units: low pressure and high pressure heaters; tight valves of pulverized coal, gas and air lines (round, rectangular); articulated and flexible non-metallic expansion joints; centrifugal and telescopic pulverized coal dividers and concentrators; STEAM and water heaters made of spiral-finned tubes; heating surfaces (plain-tube, membrane, finned); unified modules of tubular air heaters.
