THERMAL POWER PLANT Russian patent published in 2024 - IPC F01K23/10 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering and can be used at thermal power plants operating on natural gas. Proposed is a thermal power plant comprising a steam boiler, a main steam line, a steam turbine with a condenser, electric generator, condensate pump, feed tank, feed pump, gas duct for discharge of exhaust combustion products of steam boiler by means of smoke exhauster and chimney into atmosphere, natural gas is used as organic fuel, wherein thermal power plant is additionally equipped with recuperative heat exchanger, in which cooled is the desalted water obtained during the steam boiler combustion products cooling below the dew point in the condensation heat exchanger installed in the gas duct after the steam boiler on the smoke exhauster suction side, at that, the heated recuperative heat exchanger path at the inlet is connected to the initial water supply line to the condensation heat exchanger, and the recuperative heat exchanger heating path at the inlet is connected by means of a pressure pipeline and a pump to the demineralised water collection tank, and at the outlet it is connected by means of a drain pipeline to an annular water-distributing header equipped with at least four nozzles symmetrically located on the exhaust branch pipe of the steam turbine and connected to the annular water-distributing header, for injection of cooled demineralised water into a stream of steam turbine spent steam.

EFFECT: higher efficiency of thermal power plant.
