COMBINED CYCLE PLANT OF POWER PLANT WITH PARALLEL OPERATION SCHEME Russian patent published in 2024 - IPC F01K23/10 

Abstract RU 2830784 C1

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering and can be used at thermal power plants. Proposed is a combined cycle plant of a power plant with a parallel operation scheme, comprising a gas turbine plant consisting of a turbocompressor, a combustion chamber, a gas turbine, an electric generator and an exhaust gas duct for removing the gases of the gas turbine plant, heat recovery boiler, electric feed pump, supercharged power boiler, main steam line, steam turbine plant consisting of a steam turbine with a condenser, a condensate pump, a deaerator and a feed pump, electric generator, mixing chamber installed in exhaust gas duct of gas turbine plant in waste heat boiler, bypass gas duct connecting gas path of supercharged power boiler with mixing chamber, control element installed in bypass gas duct in front of mixing chamber, at that, the combined cycle plant of the power plant with a parallel operation scheme is additionally equipped with a flow rate controller of combustion products directed through the bypass gas duct into the mixing chamber from the gas path operating under supercharging of the power boiler, which is connected to the temperature sensor of the steam generated in the waste heat boiler, with temperature sensor of steam superheated in power boiler and control element installed in bypass gas duct before mixing chamber.

EFFECT: increasing the efficiency of a combined cycle power plant with a parallel operation scheme.
