Abstract:
A method for reducing the temperature of exhaust gas flowing from an exhaust gas outlet, comprising the steps of:(1) providing pressurized water with a temperature higher than a boiling point of water under atmospheric pressure, wherein the water contains alkaline agents; (2) spraying the water of step (1), into a gas cooling chamber having a wall surface and containing exhaust gas, with a temperature reduction water nozzle installed at an upper part of the gas cooling chamber in the vicinity of a gas inlet for the exhaust gas to produce micro-sized particles of atomized water; (3) evaporating the micro-sized particles of atomized water so that there is no direct impact on the wall surface of the gas cooling chamber; and (4) detecting a temperature of exhaust gas flowing from the exhaust gas outlet and controlling said temperature by controlling a volume of water sprayed into the exhaust gas in step (2).
