POWER FACILITY COMBINED-CYCLE PLANT Russian patent published in 2012 - IPC F01K23/10 F28C1/00 E04H5/12 E04H12/28 

FIELD: power engineering.

SUBSTANCE: combined-cycle plant of a power facility comprises a gas-turbine plant, a heat-recovery boiler, a steam-turbine plant, a wasteheat exchanger for exhaust gases, a circulation water supply system. The gas-turbine plant comprises a gas turbine, a turbocompressor, a combustion chamber and a power generator. The steam-turbine plant comprises a steam turbine with a condenser, a power generator and a feed pump. The wasteheat exchanger is equipped with a condensate collector with a hydraulic lock. The circulation water supply system comprises a circulating pump, a discharge pipeline to the steam turbine condenser and the wasteheat exchanger and a drain discharge pipeline to a cooling tower, comprising a stack and a storage basin. The plant additionally includes a pipeline, which connects the wasteheat exchanger with a distribution device installed in the cooling tower stack. The distribution device comprises several circular perforated headers of alternate cross section connected to each other by means of a nozzle, for even mixing of exhaust gases with a heated atmospheric air moving in the cooling tower stack and their discharge to the atmosphere.

EFFECT: no necessity to erect and operate a flue stack, which increases plant efficiency.
