PROBLEM TO BE SOLVED: To provide waste incineration disposal equipment and method preventing corrosion in an incinerator and a waste heat recovery boiler thereof.SOLUTION: There is provided the waste incineration disposal equipment including an incinerator 10 and a dust collector 30. The incinerator 10 incinerates waste fed from a waste feeding port 12 while transferring the waste toward a downstream side in a combustion chamber 11, discharges incineration ash from an incineration ash discharging part 13 at the lower part of the downstream end of the combustion chamber 11, and discharges exhaust gas from an exhaust gas discharging part 15A of the combustion chamber 11. The dust collector 30 collects dust and discharges fly ash from a fly ash discharging part 32. The waste incineration disposal equipment further includes separating and sorting device 50 for receiving at least ash being one of the incineration ash from the incineration ash discharging part 13 and fly ash from the fly ash discharging part 32, and separating and sorting the received ash into a metallic compound including at least one of Mg, Al, Fe, Si. The separating and sorting device 50 is connected to the waste feeding port 12 so that in addition to the waste, an additive agent including sulfur is fed to and metallic compound from the separating and sorting device 50 is fed to the waste feeding port 12. |
