Abstract:
A process of heat transformation to convert the low-temperature waste heat from cooling circuits of block-type thermal power station (BTPS) reciprocating-piston combustion engines into steam or other heating media of a temperature required for operation by adopting the principle of the high-temperature heat pump according to which the low-temperature heat produced by recooling the engine cooling circuits to their required inflow temperatureis transferred to a liquid working medium, is absorbed by the resultant working media vapours by working media partial evaporation, is brought, by compressing the working medium vapours from the low evaporation pressure conditioned by the recooling temperature of the engine cooling circuits, to a higher condensation pressure as is required for the transmission of heat to the inplant heating medium and is conditioned by the saturation pressure for the desired temperature of the in-plant heating medium, and is transferred by condensation to the in-plant heating medium, characterized in that the energy required for the compression of the working-medium vapours is fed fully or in part by means of a mechanical compressor utilizing the exhaust gas heat content of the BTPS reciprocating-piston combustion engine.
