COMBINED CYCLE GAS TURBINE OF POWER PLANT Russian patent published in 2019 - IPC F01K23/10 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of heat power engineering and can be used in the operating on natural gas boiler plants. To increase reliability of combined cycle gas turbine of power plant it is proposed to install air-distributing device in upper part of exhaust tower of cooling tower along its perimeter, consisting of annular variable cross-section header, equipped with rectangular-tapering nozzles directed upwards in parallel to wall of exhaust tower, and connect it by air duct with heated path of recuperative heat exchanger, heating channel of which is connected to drain pressure line to cooling tower. By means of air-distributing device to upper part of exhaust tower of cooling tower along its perimeter by fan, additional flow of heated dry air heated in recuperative heat exchanger is applied by covering jets. Feeding to the upper part of the exhaust tower of the cooling tower along its perimeter by overflows of an additional flow of heated dry atmospheric air enables to separate flow of warm and moist gases from the cold wall, to eliminate its icing and thereby to increase reliability of the steam-gas plant of the power plant.

EFFECT: higher reliability of combined cycle gas turbine of power plant.
