<p>PURPOSE: To set the temperature of combustion gas, cooled in a first gas cooling chamber, at comparatively a high temperature and permit the complete combustion of the combustion gas by a method wherein the combustion gas, generated in an incinerating furnace, is cooled primarily in a first gas cooling chamber and, thereafter, the combustion gas is introduced into a second gas cooling chamber to effect secondary cooling. CONSTITUTION: A combustion device 35 is arranged in the lower part of an incinerating furnace 31, in which a hopper 33 for supplying garbage, sludge and the like is arranged at one side thereof, while an under-furnace conveyor 37, transferring the ash of combustion, is arranged below the combustion device 35. Combustion gas G, generated in the incinerating furnace 31 and having the temperature of 900-950 deg.C, for example, is cooled in a first gas cooling chamber 49 by injection water from a water injecting device 51 to the temperature of 750-800 deg.C, for example, Subsequently, the combustion gas G is guided into a second gas cooling chamber 53 through a duct 55, then, is cooled by injection water from the water injecting device 59 to the temperature of 3 50-450 deg.C, for example, and, thereafter, is released into atmosphere from a chimney 81 through an air preheater 65 and a dust collector 75.</p> |
