<p><P>PROBLEM TO BE SOLVED: To prevent corrosion caused by corrosive high-temperature exhaust gas while preventing damage and stripping caused by a heat expansion difference between a refractory wall and a tube. <P>SOLUTION: A refractory member holding device 13 mounts the refractory wall 14 to an inner periphery of an inner cylinder 15 which guides corrosive high-temperature gas to the axis center direction. The refractory wall 14 is composed of refractory blocks 17 divided into a plurality of parts in the axis center direction and in the circumferential direction. In each group of blocks arranged along the axis center direction, the respective refractory blocks 17 are formed with holding holes 18 communicating with each other to penetrate in the axis center direction. A support rod 19 supported by the inner cylinder 15 is fitted to the holding hole 18, and an allowing clearance which allows the thermal deformation of the refractory block 17 and the support rod 19 is formed between the support rod 19 and the holding hole 18. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
