METHOD FOR OPERATION OF A THERMAL POWER PLANT Russian patent published in 2022 - IPC F01K11/02 

FIELD: energy.

SUBSTANCE: invention relates to energy and can be used at thermal power plants. Method for operation of a thermal power plant is proposed, according to which organic fuel, atmospheric air and feed water are supplied to the furnace of a steam boiler, where the combustion process of organic fuel is carried out with the formation of combustion products heated to a high temperature and water vapor is generated, water vapor is sent through the main steam pipeline to the steam boiler. turbine, and the cooled combustion products are discharged into the atmosphere through the gas duct, in the steam turbine during the expansion of water vapor, the useful work of the steam-power cycle is performed, which is spent on driving the electric generator, the steam exhausted in the steam turbine is removed to the condenser, in the condenser the water vapor is condensed due to heat exchange with circulation water supplied by the circulation pump through the pressure pipeline from the catchment area of ​​the cooling tower with natural draft, and the circulation water is heated, the circulation water heated in the condenser is fed through the discharge pressure pipeline to the exhaust a natural draft cooling tower, where it is sprayed by means of a water distribution device and cooled by cold atmospheric air in the fill, cooled circulating water flows into the drainage basin, and heated and humidified atmospheric air passes through the water trap and is discharged into the atmosphere, the condensate of the steam exhausted in the steam turbine from the condenser is sent to the feed tank by the condensate pump, from which it is fed to the steam boiler by the feed pump, while the exhaust of cooling towers with natural draft are provided with rigidly fastened annular gas distribution manifolds with rectangular holes directed upwards and a casing of circular cross-section, forming, together with the wall of the exhaust tower of the natural draft cooling tower, a near-wall channel of an annular section, and the outgoing combustion products of the steam boiler are supplied through the gas duct to the annular gas distribution manifold and through the rectangular holes made in it, they are sent to the near-wall channel of the annular section, through which the outgoing combustion products of the steam boiler are discharged into the atmosphere, in addition, the annular gas distribution The flax collector must be placed after the water trap in the direction of moist air movement and connected to the gas duct for the removal of the exhaust combustion products of the steam boiler into the atmosphere.

EFFECT: increasing the efficiency and reliability of a thermal power plant.
