SMALL SHIP POWER PLANT WITH ELECTRIC PROPULSION Russian patent published in 2024 - IPC B63H21/20 B63H23/24 

FIELD: power engineering.

SUBSTANCE: invention relates to power plants on ships. Power plant of small-size vessel with electric propulsion contains diesel engine with generator, high-temperature two-stage compressor, steam turbine with generator, main switchboard, storage batteries, control panel, propeller motor, propeller shaft, propeller screw, control controller, capacitor, four electric pumps, evaporator, organic Rankine cycle capacitor (ORC), regenerator, ORC evaporator, outboard box, heat exchanger, additional heat exchanger, non-return valve, three-way valve, electric four-way valve, shutoff valve, heat energy consumer, exhaust pipeline. At that, closed loop of organic Rankine cycle, through which low-boiling substance circulates, includes ORC evaporator, steam turbine, regenerator, ORC condenser and third electric pump, connected by channels. ORC condenser, the ORC evaporator and the evaporator are connected by channels to the heat energy consumer. Heat exchanger in which thermal oil circulates is provided on the exhaust pipeline of diesel exhaust gases.

EFFECT: higher fuel efficiency of small-size vessel with electric propulsion.
