Combined Cycle Plant on base GTU89-PT- 20, Power 60-120MW.
Combined gas and steam energy-block is performanced on traditional plan. On the single frame the gas generator and the power turbine are mounted. Shaft of power turbine through the gas collector is joined with a generator alternating current.
The unit realizes a combined cycle (gas and steam). Steam is move in the flowing part of turbine. The block GTU is built by steam boiler is calculated on two level of pressure. High pressure ~ 90 kg/sm³ and temperature 600 0C for the steam turbine that are running jointly with the gas turbine. Steam of low pressure is use for cooling of the components flowing part the unit. Mixture of gas and steam is cool in steam boiler about 90-1000C and move into condenser and there is condense about 40-500C. Condensate then moves again in cycle.
