SELF-CONTAINED ELECTRIC-AND-HEAT SUPPLY PLANT Russian patent published in 2004 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: proposed plant contains diesel engine, heat exchanger devices installed in diesel engine liquid cooling and lubricating circuits, gas-liquid heat exchanger with intake and outlet branch pipes connected by gas line with exhaust pipeline of diesel engine and by water circuit, with external heat supply network. Plant is furnished additionally with heat accumulator, for instance, on phase transition base, built into gas-liquid heat exchanger, steam-gas turbocompressor consisting of steam turbine and gas compressor. Intake branch pipe of steam turbine communicates with outlet branch pipe of heat accumulator, and outlet branch pipe communicates through steam trap unit with pipeline of return heating system water pipeline, intake branch pipe of gas compressor communicates with exhaust conduit of diesel engine, and outlet branch pipe communicates with gas duct of gas-liquid heat exchanger. Intake branch pipe of gas-liquid heat exchanger communicates with outlet of turbocompressor of diesel engine supercharging system, and supercharging air cooler is placed in heat supply circuit.

EFFECT: increased economy at peak loads.
