PROBLEM TO BE SOLVED: To provide refuse incinerator equipment capable of easily reducing re-synthesis of dioxin, and particularly waste gas processing equipment including a stoker type incinerator. SOLUTION: A heat storage heat exchanger 12 is provided, which removes dust in combustion gas after through passage a high temperature dust removal apparatus 11 of combustion gas just after exhausted from a dust incinerator 2 and hence the main factor of dust is firstly removed, and then heat-exchanges with ordinary temperature air. In the heat exchanger 12, combustion gas is rapidly lowered to about 250 deg.C or lower, and ordinary temperature air is supplied to the heat storage heat exchanger 12 for heat exchange with the combustion gas. Air becoming high temperature after the heat exchange is brought into heat contact in a heat recovery apparatus (vapor generator 14) or with water vapor. |
