STEAM-GAS PLANT Russian patent published in 1995 - IPC

FIELD: heat power engineering. SUBSTANCE: plant, provided with steam cooling of gas turbines, additionally has gas-water economizer for system water, heat pump, hot water accumulator, deaerator, and drain collector. The system water economizer is connected to the water path downstream of the system heater, and to the heating fluid path downstream of the supplying water economizer. The evaporator of the heat pump is connected to the delivery and drain cooling water ducts of the steam turbine condenser. The condenser of the heat pump is connected to the inlet and outlet sides of the heat accumulator which is, in turn, coupled with water space of the drain collector via the inlet side. The drains of the heaters of low pressure and condenser are also coupled with the water space of the drain collector. The steam space of the drain collector is connected to the steam space of the heaters of low pressure. The output side of the accumulator is connected to the pipe line coupled with the deaerator. EFFECT: enhanced efficiency. 1 dwg
