INSTALLATION FOR GENERATING THERMAL AND MECHANICAL ENERGY AND METHOD OF ITS OPERATION Russian patent published in 2023 - IPC F02C3/00 F28B5/00 F28B7/00 B01D5/00 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to methods and installations for environmentally friendly generation of mechanical and thermal energy. The installation for generating thermal and mechanical energy consists of combustion chambers (1, 12) of high and low pressure, steam-gas turbines (2, 13), lines for supplying carbon dioxide, liquefied natural gas (LNG) and oxygen to the combustion chambers (1, 12), recuperative coolers (4, 3) of exhaust gases, a condenser (5) of carbon dioxide with a refrigeration unit (6), heat exchangers of a condenser (5) of carbon dioxide and a heat exchanger (8) for heating oxygen and LNG, low and high pressure contact heat exchangers (9, 10) connected to the compressor (7), carbon dioxide heater (11). The connection of the low-pressure combustion chamber (12) with sources of LNG and oxygen, with a low-pressure contact heat exchanger (9) and with a carbon dioxide condenser (5) is disclosed. The high-pressure steam-gas turbine (2) output is connected to the low-pressure combustion chamber (12) input. The output of the low-pressure steam-gas turbine (13) is connected to the carbon dioxide condenser (5) in series through recuperative exhaust gas coolers (4, 3), a low-pressure contact heat exchanger (9), a compressor (7) and a high-pressure contact heat exchanger (10).

EFFECT: increasing the useful work in the cycle due to several heating of the working gas, increasing the efficiency of the installation cycle, as well as eliminating the need for constant purging of the carbon dioxide condenser.
