INSTALLATION FOR GENERATION OF HEAT AND MECHANICAL ENERGY AND METHOD OF ITS REGULATION Russian patent published in 2020 - IPC F02C3/00 F28B5/00 F28B7/00 B01D5/00 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat power engineering, namely to methods and installations for environmentally friendly operation of mechanical and thermal energy. Installation for generation of heat and mechanical energy consists of combustion chamber (1) connected to steam-gas turbine (2), coolers (3, 4, 13) of exhaust gases, condenser (14) connected to heat pump (17), compressor (12), oxygen source (15) and carbon-containing fuel source (16) connected to combustion chamber (1). Plant additionally comprises low-potential heat energy utilization circuit (5), which includes turbine (7) connected to generator, condenser (8) of low-boiling working medium, pump (9) of low-boiling working medium and at least three heat exchangers-waste heaters (6), made with possibility of heat transfer from exhaust gases to low-boiling working medium. Temperature of low-boiling working medium increases in direction from condenser (8) of low-boiling working medium to turbine (7). At least one heat exchanger-waste heat exchanger (6) is connected to second cooler (4) and contact heat exchanger (10), made with possibility supply by means of pump (11) of water condensed from waste gases through at least one other heat exchanger-heat exchanger (6) into first waste gas cooler (3) and to consumer. At least one third waste heat exchanger (6) is also configured to transfer heat to the low-boiling working body of recycling circuit (5) from water discharged by pump (22) from the second contact heat exchanger (13) and supplied to the consumer and to unit (18) cooling water. Additionally, the plant comprises an ambient air temperature sensor. Also disclosed is a method of controlling a plant for generating heat and mechanical energy.

EFFECT: technical result consists in improvement of plant efficiency due to use of low-potential heat generated by the plant.
