The 10th anniversary was celebrated by the first gas turbine power plant in the Bashkir Trans-Urals - GTPP Sibay. Cogeneration power unit GTPP-16PA with waste-heat boiler 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, devising by JSC UEC-Aviadvigatel (Perm), operates in combined energy generation mode. The design is based on the GTE-16PA gas turbine with the PS-90EU-16A engine made based on the gas generator of the high-performance aircraft engine PS-90A2.

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. As the main fuel 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 booster compressor unit supplied by ENERGAS. The packaged BCU in a container version is equipped with necessary life support and safety systems. The unit 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, ten CHPPs, two large HPPs as well as facilities of small power industry. At present, the installed capacity of BGC enterprises is 4,461 MW for electricity and 8,578 Gcal / h for heat.
