PURPOSE:To prevent a tube and a support structre therefor from being damaged thereby to increase the stability of the device by providing an auxiliary support plate moving by following after the thermal deformation of the tube, an evading a thermal expansion of a tube in the internal part of a moisture content separation heater without sticking the tube. CONSTITUTION:An auxiliary support plate 17 is mounted in a final support plate 9 closest to a U-shaped bent point 11 among support plates 9 constituting a stationary frame 8. With the suspension of the tube downward due to the thermal deformation of the tube, the leg portion of the tube presses the lower side of a hole of the auxiliary support plate 17. The auxiliary support plate 17 moves downward while pulling a coil spring 18. When the tube is cooled and contracts, the auxiliary support plate 7 is pulled by the coil spring 18 and moves upward. Since the tube is supported at two points, i.e., the upper side of the hole of the final support plate 9 and the lower side of the hole of the auxiliary support plate 17 with respect to the deformation in a certain range, the vibration inhibiting effect of the tube is not lost. By the movement of the auxiliary support plate 17, it is possible to support the tube without preventing the natural deformation of the tube. Therefore, it becomes possible to alleviate the lateral stress of the tube. |
