SYSTEM OF WET SPARK QUENCHING OF EFFLUENT GASES OF POWER PLANT Russian patent published in 1999 - IPC

FIELD: heat power industry. SUBSTANCE: system of wet spark quenching of effluent gases of power plant has interconjugate source of stack gases, spark extinguisher communicating with water tank, confuser, chamber feeding additional air and gas conduit With operation of boiler unit 5 gases are washed in spark extinguisher 3 with feed of water from tank 8, are cooled and are 75% free from soot. Soot pulp is tapped away over pipe-line 4, gas goes to confuser 2, is accelerated and turbulized and particles of soot remaining in flow burn down intensively. Later accelerated gas goes to chamber 9 feeding air, mixes with it and moves over gas conduit 1 to exit and remaining particles of incomplete fuel combustion burn down more completely. Effluent gas carries smaller quantity of carbon monoxide, soot and sparks. EFFECT: reduced heat removal in gas conduit, prolonged operational life of it and improved ecological indices. 1 dwg
