Feeding of fuel gas with the specified design parameters in terms of purity, temperature, pressure and flow rate to the GTPP turbine is provided by the ENERGAS booster compressor unit.

The 15th anniversary was celebrated by the first gas turbine power plant in the Bashkir Trans-Urals - GTPP Sibay. Cogeneration power unit GTPP-16PA was commissioned in April 2011 within frame of Zauralskaya CHPP enlargement project (Sibai city, Republic of Bashkortostan). New capacities amounted to 16 MW for electricity and 95.54 Gcal / h for heat.

Power plant GTPP-16PA was devised by JSC UEC-Aviadvigatel (Perm) and manufactured by UEC-Perm Motors enterprise. The design is based on the GTE-16PA gas turbine unit with the PS-90EU-16A drive made based on the gas generator of the high-performance PS-90A2 aircraft engine.

The main difference between the PS-90EU-16A and the industrial engines previously created by the Perm design bureau is the use of a free four-stage power turbine with a nominal speed of 3000 rpm. When using this design, the turbogenerator is driven directly without using a reducer. This reduces operating costs and generally increases the reliability of the power plant.

For issuance of the thermal power, hot-water type waste-heat boiler is installed here, conjugated with GTU. It heats the water using the high temperature of the turbine exhaust gases. The boiler produced by the Belgorod plant Energomash is made with the envisaged bypassing of the exhaust, which allows it to be taken out of operation without shutting down the gas turbine engine.

As a result, the cogeneration cycle provides combined energy generation, high fuel effectiveness (at least 85%), environmental friendliness and efficiency of the facility. As the main fuel for power unit there is used natural gas (reserve fuel is severin).

Feeding of fuel gas with the design parameters on purity, temperature, pressure and flow rate to the turbine is provided by the ENERGAS booster compressor unit. The packaged unit in a container version is equipped with necessary life support and safety systems. The unit with a capacity of 6,000 m3 / h operates in an automatic mode; monitoring and control are carried out from the central panel of the GTPP.



REFERENCE:

Zauralskaya CHPP is the easternmost branch of the Bashkir Generation Company (BGC). Power plant is the main source of electricity for the Bashkir Trans-Urals and heat for Sibai. The total electric capacity of the CHPP and its separate subdivision GTPP Sibai is 33.44 MW; the heat capacity is 124 Gcal / h.

BGC LLC (part of PJSC Inter RAO) is one of the largest local energy companies of Russia, it owns large production base consisting of one SDPP, eleven CHPPs and TPPs, three HPPs and one wind farm.
