PURPOSE:To make the generation of thermal stress in baffle plates difficult by a structure wherein a combustion chamber is provided at the inside of a corrugated inner shell and a baffle body is arranged in the interior of the inner shell so as to locate the tips of baffle plates at convex parts of the inner shell. CONSTITUTION:A square pole-shaped baffle body 15 with both ends closed is freely detachably provided in a combustion chamber 4. Segment-shaped baffle plates 16A and 16B are attached horizontally at proper intervals in 8 stages onto the respective four plane sides of the baffle body 15. Three slits 17 are provided in each baffle plate 16A, which lies in the lowest three stages. In addition, the tips of each baffle plate 16A, which lies in the lowest two stages, is arranged at the position of the convex part of the inner shell 1. Because the temperature of the baffle plate 16B is comparatively lower, no deformation of the baffle plate 16B occurs. On the other hand, the temperature of the baffle plate 16A becomes higher. However, the generation of thermal stress in the baffle plate 16A is difficult, because the baffle plate 16A is allowed to comparatively freely expand itself thermally due to the effect of the slits 17. |
