EXHAUST GAS PURIFICATION SYSTEM FOR WASTE INCINERATOR

摘要

PROBLEM TO BE SOLVED: To provide an exhaust gas mixing system for waste incinerator in which dioxins and nitrogen oxides are reduced by suppressing and averaging time variation in the exhaust gas components of the incinerator thereby operating an exhaust gas recombustor stably. SOLUTION: In a system for purifying exhaust gas from a waste incineration facility by recombusting the exhaust gas through an exhaust gas recombustor, an exhaust gas duct 22 from the waste incineration facility is provided with a branch section 30 on the downstream side and a combining section 31 on the upstream side. The branch section and the combining section are coupled in loop through a branch pipe 33 into which the exhaust gas is shunted.
