GAS-TURBINE PLANT POWER STABILIZING DEVICE Russian patent published in 1999 - IPC

FIELD: heat power engineering; gas industry; gas transfer units. SUBSTANCE: air washer is connected to inlet branch pipe of gas-turbine plant air compressor. Air washer is made in form of two-stage ejector scrubber. Nozzles of first stage (in direction of air flow) of scrubber are connected to service water inlet manifold, and nozzles of second stage are connected to outlet of circulation pump whose suction end is connected with cooled distillate outlet branch pipe of gas ejector cooling plant evaporator. Outlet liquid branch pipe of first stage of air washer is connected in series with filter, circulation pump and nozzles of first stage (in direction of exhaust gas flow) of gas cooler (made in the form of two-stage ejector scrubber connected to outlet branch pipe of gas-turbine plant), and outlet liquid branch pipe of second stage of air washer is connected to inlet branch pipe of heated distillate of gas ejector cooling plant evaporator. Nozzles of second stage of gas cooler are connected to outlet manifold of distillate cooler, and outlet liquid branch pipe of second stage of gas cooler is connected to series - connected circulation pump and distillate cooler inlet manifold. Outlet manifold of distillate cooler is connected also to evaporator of gas ejector cooling plant, and outlet branch pipe of heated distillate of gas cooler second stage is connected to circulation pump whose outlet is connected with inlet manifold of distillate cooler and external heat supply system. Inlet branch pipe of working medium ejector of gas ejector cooling plant is connected to high pressure fuel gas manifold, and outlet branch pipe of steam-gas mixture of ejector is connected to separator whose liquid outlet branch pipe is connected to evaporator of gas ejector cooling plant, and outlet gas branch pipe of separator is connected with gas flow regulator of gas-turbine plant. EFFECT: provision of stabilization of gas-turbine plant outlet power at high and low ambient temperatures. 1 dwg
