To provide a vibration-proof supporting structure for heating tubes which are set in a fluidized bed.
The part of a vibration-proof member receiving the pressure of heating tubes is made into a wide area and flexible structure. More specifically, a flat plate 32 is provided with a curved part 32a having semi-arcuate cross-section, by bending work and two vibration-proof member 32, 32 are combined to obtain a structure where the vibratory load of tubes constituting heating tubes 9 are received by the bottom face at the curved parts 32a, 32a having wide plate width. Furthermore, a welding line 32b of two plates 32, 32 is located on the inner surface side of the two pasted vibration-proof members 32, 32 and fluid medium is prevented from reaching the heating tubes 9 directly from the outside of the plate 32 to cause corrosion through abrasion.
