COMBUSTION PROCESSING METHOD OF HALOGEN COMPOUND

摘要

PURPOSE: To improve a decomposition rate of halogen compounds by forming a high temperature combustion gas atmosphere by combusting combustion air and fuel in an incinerator, and supplying and combusting the halogen compounds to the high temperature combustion gas atmosphere for thermal decomposition thereof. CONSTITUTION: Fuel F such as city gas is supplied from a fuel supply pipe 7 into an incinerator 1. Combustion air A that is pressurized by a blower 2 and heated and raised in temperature to 300 deg.C to 500 deg.C by a heater 3 is supplied through a combustion air supply pipe 4 toward the fuel F injected from a nozzle at the tip end of the fuel supply pipe 7 to form high temperature combustion gas atmosphere Ga at 1300 deg.C or higher. Factory waste gas, for example, containing halogen compounds in the high temperature combustion gas atmosphere Ga is supplied from a halogen compound supply pipe 8 and combusted for thermal decomposition. Hereby, a decomposition rate of the halogen compounds to be processed is improved.
