HYDRAULIC STEAM TURBINE PLANT Russian patent published in 2025 - IPC F01K13/00 F03G7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to equipment used at geothermal power plants and waste heat recovery systems. Hydro steam turbine plant, which is characterized in that it includes: an evaporator heated by a heating heat carrier; economizer heated by heating heat carrier supplied from evaporator outlet; pump forcing the liquid working medium flow from the condenser to the economizer inlet and then from the economizer outlet part of the flow through the liquid flow control valve to the inlet to the hydro-steam turbine and part of the flow through the liquid flow throttle to the evaporator inlet, wherein the liquid flow control valve is controlled by the working medium vapour temperature at the evaporator outlet. At the same time the plant additionally includes the following: steam turbine, into which the working medium steam is supplied from the evaporator outlet, mechanically connected to the hydro-steam turbine and the mechanical power consumer, wherein the working medium steam enters the steam turbine through the steam control valve controlled by the turbine rotor speed; a steam separator separating the working medium steam from the steam-liquid mixture coming from the outlet of the hydro-steam turbine; cooled by heat carrier from the environment working medium steam condenser coming from the steam turbine outlet, as well as from the separator. Thus, the above steam flow from the separator passes through the pressure regulator "to itself", and the liquid flow from the separator, in its turn, flows under gravity into the condensate collector of the condenser. Besides, the plant also includes a bypass line with a pressure regulator "to itself", which provides overflow to the condenser of the working medium vapour coming from the evaporator.

EFFECT: stable operation of hydraulic steam turbine plant in all operating modes.
