STEAM TURBINE PLANT WITH JET EJECTOR AND EXHAUST STEAM RECOVERY Russian patent published in 2022 - IPC F01K7/34 F22B21/34 

FIELD: ship power engineering.

SUBSTANCE: invention relates to the field of ship power engineering and relates to the design of a steam turbine plant of a ship with electric propulsion. The steam turbine plant contains a steam boiler with a hearth burner and evaporative heating surfaces, a condenser, a feed pump, a gas regenerative air heater, an electric generator, a blower, a feed water heater, a superheater, while the evaporative surface of the boiler is formed by vertical pipes with upper and lower annular collectors, to which the ends of the pipes are attached, while the hearth burner is located in the center of the lower annular collector, and the upper annular collector serves as a drum (steam collector) of the boiler, limiting the furnace volume of the boiler from above, and the perimeter of the evaporator pipes forms a combustion chamber of the boiler furnace volume, while the coil-type cylindrical superheater is suspended to the boiler drum above the combustion chamber; mixing, with an annular diffuser facing the flow path of the turbine, the exhaust steam from the turbine enters the compressor, and from it into the regenerative feed water heater, where the steam is cooled, heating the feed water, part of the steam returns to the receiving chamber of the annular jet ejector, and the other part of the steam is sent to the condenser, the condensate is supplied by the feed pump to the regenerative feed water heater, and from it to the lower annular collector of the boiler, while the flue gases from the boiler are removed through the annular tubular regenerative air heater, which limits the furnace volume of the boiler and receives air from the blower.

EFFECT: invention makes it possible to simplify the design, control, regulation and improve the efficiency of the STP.
