PLANT TO RECOVER HEAT OF STACK GASES Russian patent published in 2002 - IPC

FIELD: power engineering, recovery of waste stack gases in power engineering installations. SUBSTANCE: plant to recover heat of stack gases has recovering heat exchanger and heat exchanger of intermediate transfer agent mounted one opposite another at equal distance from sprinkler installed in front of them. Heated passage of heat exchanger of intermediate heat transfer agent is joined with inlet to moisture collector. Nozzles of sprinkler are directed to side opposite to heat exchangers. Plant is supplemented with another heat exchanger for additional heating of sprinkling water installed in gas passage and placed above sprinkler. Heated passage of it is connected with inlet to heat exchanger of intermediate heat transfer agent and with outlet to sprinkler. EFFECT: increased functional efficiency of plant thanks to more complete recovery of heat. 1 dwg
