COMBINED POWER PLANT WITH STEAM POWER UNIT Russian patent published in 2021 - IPC F01K23/14 

FIELD: engine technology.

SUBSTANCE: invention relates to the field of engine building, namely to heat engines for the production of mechanical energy. The technical problem lies in the possibility of operation of a combined power plant with a steam power unit both at rated power and in partial operating modes. The expected result is achieved in a combined power plant with a steam power unit containing a reciprocating internal combustion engine, a recycling boiler, a steam engine, a radiator, a storage tank and a high-pressure liquid pump connected in series, while the recycling boiler is cylindrical with two concentrically arranged channels, and the central channel is designed to move the exhaust gases of the internal combustion engine, and the peripheral is supplied with working fluid from a high-pressure liquid pump, and the steam engine is kinematically connected to the crankshaft of the internal combustion engine, speed and torque sensors are installed on the crankshaft of the internal combustion engine, transmitting signals to the control unit about changes in the power of the internal combustion engine, while the control unit contains information about the amount of heat contained in the exhaust gases at rated power, as well as partial operating modes, and it is made with the possibility of regulating the amount of the supplied working fluid by transmitting control signals to the electric motor of the drive of the high-pressure liquid pump to change its rotation speed and the corresponding change in the supply of working fluid to the recycling boiler.

EFFECT: possibility of regulating the amount of liquid supplied depending on the load.
