In the course of the work, two AP-6 steam turbines with a capacity of 4.6 MW each from the Czech Skoda plant, produced in 1953 and 1954, were dismantled. Instead of the exhausted turbines, two steam turbo units TWIN KK&K CA56 (Howden Turbo GmbH) with an electrical capacity of 6 MW each were installed. To control them, an automated process control system is provided.

Also, within the framework of the project, the steam pipelines of boilers st. No. 5-7 were replaced, the collectors of the selected steam were reconstructed. The results of the upgrade will be the saving of fuel and energy resources in the amount of 2.9 thousand tons of standard fuel per year and the reduction of pollutant emissions – nitrogen oxides by 17, and carbon oxide by 3 tons per year. The electric capacity of Mogilev CHPP-1 increased by 2.8 MW and amounted to 50.5 MW.

Large-scale first stage of reconstruction of the MCHPP-1 with use modern combined-cycle technologies was carried out from August 2014 to December 2016. The four obsolete steam boilers st. No. 1-4 were dismantled, and in their place there were installed a gas turbine LM2500+ (General Electric) with a rated electrical capacity of 26.5 MW and a waste-heat boiler К-37/3.9-346 (NPO BZKO) with a steam capacity of 37 ton / h.



The new generating equipment operates in cogeneration mode and is integrated into existing process flow diagram of power plant with discharge of steam into the overall line. Fuel is natural gas.

To feeding fuel gas to the power generating unit, the facility was equipped with special process equipment – ENERGAS gas treatment system which comprises a booster compressor station of two package units, a preliminary gas filtration unit, and an underground drainage tank for condensate gathering.



The first stage of MCHPP-1 reconstruction has ensured additional power generation 157.6 million kWh a year and saving almost 18 thousand tons of reference fuel per year, improved the environment, increased maneuverability of the power grid, the reliability of heat and power supply to all kind of consumers. The power plant electrical capacity increased almost 2.5 times – from 21.2 to 47.7 MW.

REFERENCE:

Mogilev CHPP-1 is the oldest power plant in Mogilev Region. The first steam boiler with a capacity of 25 tons of steam per hour was put into operation on October 15, 1931, and in April 1933, a turbine unit with a capacity of 5 MW was launched. Lumpy peat served as fuel, supplied from the left bank of the Dnieper by cableway over two kilometers long.

During the Great Patriotic War, the power plant was destroyed. After the liberation of Mogilev, its restoration began. Over the years of its existence, the equipment of MCHPP-1 has been repeatedly upgraded, and the emergence of new technologies makes it possible to increase energy efficiency.
