METHOD FOR TREATING EXHAUST GAS AND ITS APPARATUS

摘要

PROBLEM TO BE SOLVED: To decompose dioxins by heating exhaust gas exhausted from a refuse incinerator under high temp. atmosphere in a flue. SOLUTION: A plurality of burners 5 are fitted along the inner wall of a flue in the crosssectional face direction and oxygen and hydrogen gas are generated by electrolysis of water as a means for feeding gas for burning to a burner unit 4 and air is fed and mixed with oxygen gas by means of an air pump 10 to change the ratio of (oxygen + air) in hydrogen. Burning temp. of the burner unit 4 is controlled at a high temp. of 1,300-1,500 deg.C by this constitution to decompose dioxins with a high speed.
