COGENERATION PLANT Russian patent published in 2021 - IPC F02G5/04 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of energy and is intended for the simultaneous production of thermal and electrical energy using cogeneration plants with an internal combustion engine (hereinafter referred to as ICE) and can be used as a mini-CHP generating thermal and electrical energy for the needs of industrial and municipal consumers. The cogeneration plant contains a gas-piston ICE with an electric generator on the same shaft with it, its cooling system with a pump, a heat recovery system, hydraulic lines, a circulation pump of a heat recovery system, an exhaust gas pipeline, valves, a natural gas pipeline, a vortex heat generator, a device for generating electricity using low-potential heat carriers and a thermal power plant with a diesel ICE on the same shaft with it. Before the heat exchanger-heat exchanger of the cooling system of the gas-piston ICE, there is a circuit consisting of heat exchangers-waste heat boilers of the stator and rotor of the electric generators of the ICE, hydraulic lines and three-way cranes, which makes it possible to preheat water intended for the needs of consumers.

EFFECT: increase in the energy efficiency and performance coefficient of the cogeneration plant due to the utilization of heat from the stator and rotor windings of ICE electric generators for heating water for the needs of heating and hot water supply systems for municipal consumers and the industrial enterprises’ own technological needs.
