REFUSE INCINERATION EQUIPMENT AND WASTE GAS COOLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide refuse incineration equipment and a waste gas cooling method in which a trouble due to wet ash and low temperature corrosion are prevented from being caused. SOLUTION: On a desuperheating tower 30 a heat exchanger 40 is disposed for heating cooling water effused from an injection water pump 36. To the heat exchanger 40 a cooling water temperature adjusting valve 42 is connected for controlling heating temperature for the cooling water. The degree of opening and closing of the cooling water temperature adjusting valve 42 is adjusted with a cooling water temperature controller 44 based upon the temperature of the cooling water after being effused from the heat exchanger 40. Hereby, the cooling water heated to a predetermined temperature is injected into the desuperheating tower 30 from a nozzle 32.
