METHOD FOR OPERATION OF BINARY COMBINED CYCLE POWER PLANT Russian patent published in 2017 - IPC F01K23/10 

FIELD: power industry.

SUBSTANCE: invention can be used at heat power plants, namely in the operation of binary combined cycle of heat and power plant (CCHPP). The exhaust gases of the gas turbine plant enter the waste-heat boiler, the steam processed with the waste-heat boiler is then fed to expand and complete work in the heating steam turbine. The reduced steam from the reduction-cooling plant (RCP) is used for heating and deaeration of chemically treated water of the heating network feed, a part of the steam from the steam turbine heat extraction is diverted to the upper and lower network heaters for heating the network water. The rest part of the steam is sent to the condenser, the condensate from which is pumped to the waste-heat boiler. The exhaust gas of the waste-heat boiler is used for heating chemically purified water of the heating network in the gas-water heater, the steam flow is reduced through the reduction-cooling plant (RCP), thereby increasing the steam fed in the flow part of the steam turbine.

EFFECT: invention enables to increase electric power of binary combined cycle power plant.
