PROBLEM TO BE SOLVED: To provide a clinker sticking preventive furnace wall structure for a waste heat treatment furnace, capable of making clinker hard to be stuck, and forcedly removing the clinker even if stuck. SOLUTION: This furnace wall structure comprises a insulating refractory material 8 lined with a plurality of steel plates 1, and a fixing means 2 passed through the insulating refractory material to support the unit steel plate 1 in contact thereto at least on the periphery of the unit steel plate 1. The fixing means 2 includes a displacement member 7 displacing the fixing means 2 in the direction of passing through the material 8 by an impact force from the outside of the furnace, a shaft member 4 passed through the insulating refractory material, a heat insulating support member 3 provided at the furnace inside tip of the shaft member to support the steel plate 1 in contact thereto, and a shaft fixing member provided so as to be exposed from the furnace at the other end side of the shaft member, and fixing the shaft member. The displacement member 7a is an elastic member such as a coil spring interposed between the insulating refractory material and the shaft fixing member. COPYRIGHT: (C)2006,JPO&NCIPI
