INSTALLATION FOR GENERATING THERMAL AND MECHANICAL ENERGY AND METHOD FOR ITS REGULATION Russian patent published in 2022 - IPC F02C3/00 F28B5/00 F28B7/00 B01D5/00 

FIELD: thermal power engineering.

SUBSTANCE: invention relates to the field of thermal power engineering, and in particular to methods and installations for environmentally friendly generation of mechanical and thermal energy. The installation for generating thermal and mechanical energy consists of a combustion chamber (1) connected to a combined cycle turbine (2), oxygen (11), carbon dioxide (13), fuel (16) and water (18) pump-regulators, coolers (3, 4, 6, 8) exhaust gases (EG), two (6, 8) of which are contact coolers of EG, carbon dioxide condenser (9), connected to heat pump unit (17), compressor (7), sources of oxygen and carbon-containing fuel connected through a block (10) for liquefying carbon-containing fuel with a combustion chamber (1), a steam turbine block (19) of the organic Rankine cycle (ORC), including a condenser (24) of a low-boiling working fluid, a feed pump (23), heat exchangers (5, 21, 22) ORC, an ORC turbine (20) connected to a turbogenerator (27), wherein at least one first ORC heat exchanger (22) is a low-boiling working fluid heater, at least one second ORC heat exchanger (21) is an evaporator of a low-boiling working fluid, and at least one third ORC heat exchanger (5) is a superheater of a low-boiling working fluid, while the water inlet of at least one first ORC heat exchanger (22) is connected to the condensed water outlet of the second exhaust gas contact cooler (8) through a circulation pump (15 ), and the water outlet of at least one first ORC heat exchanger (22) is connected to the second contact heat exchanger (8), also the water inlet of at least one second ORC heat exchanger (21) is connected to the return water line from the heating network, and the outlet for water of at least one second heat exchanger (21) ORC is connected to the inlet of the first contact cooler (6) EG, the water inlet of at least one third ORC heat exchanger (5) is connected through a water pump-regulator (18) to the water outlet of the first exhaust gas contact cooler (6), while the water outlet of at least one third ORC heat exchanger (5) is connected with the combustion chamber (1) through the first exhaust gas cooler (3). Also disclosed is a method for regulating an installation for generating thermal and mechanical energy.

EFFECT: increasing the efficiency of the installation by increasing the use of low-grade heat generated by the installation.
