COGENERATION POWER PLANT Russian patent published in 2024 - IPC F02C6/18 

FIELD: energy.

SUBSTANCE: invention is intended for the simultaneous production of thermal and electrical energy and can be used as autonomous power plants for stationary and mobile objects, and in particular for remote residential and industrial facilities. The cogeneration power plant comprises a fuel combustion chamber, a steam generator, a steam engine, including a housing, inside of which there is a working element with a shaft drive, which is mechanically connected to an electric generator, a steam condenser, a coolant heating system for external heat supply with a sectioned surface heat transfer, with sections of the heat transfer surface located in the steam condenser and in the gas duct for fuel combustion products. The unit has a working body of the steam engine in the form of a disk, the axis of which is aligned with the axis of the shaft connected to the electric generator; along the outer edge the disk covers a cylindrical ring, on the outer surface of which hinges are installed with equal spacing, the axes of which are parallel to each other and to the shaft axis connected to the electric generator, blades are fixed on the hinge axes with one edge equipped with stops and capable of rotation, the steam generator is located in the lower part of the steam engine housing under the working element, a guide sheet for steam flow is installed between the working element and the steam generator, the condenser is located in the upper part the housing of the steam engine above the working body, the housing of the steam engine forms a lifting channel for the passage of steam and a lowering channel for the passage of liquid, whereas the lifting and lowering channels connect the spaces of the steam generator and the steam condenser, and are fixed to two oppositely located side walls of the steam engine housing with their ends arc stops covering with a gap part of the circumference of the cylindrical ring. The steam generator has a heat transfer surface consisting of one or several rows of slotted channels for the passage of fuel combustion products, and ribbed inserts are installed in the channels; a stationary layer of granular catalyst particles is placed in the cross section of the passage of combustion products in the fuel combustion chamber.

EFFECT: simplified design and increased efficiency, making it possible to use any fuel, including low-quality and combustible waste.
