FURNACE BODY COOLING DEVICE OF WASTE GASIFYING MELTING FURNACE AND FURNACE BODY COOLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a furnace body cooling device capable of improving the durability of a furnace wall refractory of a portion in contact with molten slag particularly severe in wear in a waste gasifying melting furnace, and a furnace body cooling method.;SOLUTION: In the furnace body cooling device for cooling a refractory on the furnace body inner face of the waste gasifying melting furnace 1 for treating waste by gasifying melting treatment, a cooling water line 3 having a furnace body iron shell of the waste gasifying melting furnace 1 as a portion of the pipeline is disposed with predetermined intervals. A silicon carbide refractory on the furnace body inner face is cooled by directly cooling the furnace body steel shell.;COPYRIGHT: (C)2009,JPO&INPIT
