Abstract: PURPOSE: To reduce the low temperature corrosion proceeding during the stopping of the operation of an incinerator by a method wherein the exhaust gas existing in the domain ranging from the heaped portion of matters to be incinerated in the incinerator to a stack are replaced with the fresh air after the stoppage of supply of matters to be incinerated.
CONSTITUTION: The replacement of the exhaust gas in an exhaust gas passage with the fresh air by continuously supplying fluidizing air for 2W3 minutes after the stoppage of supply of matters to be incinerated in an incinerator and then supplying secondary air from the so-called free board part 3b, which is the space above the fluidized bed or the heaped layer 3a of matters to be incinerated within an incinerator, is enough for corrosion prevention. In such a manner as mentioned above, the fresh air supplied to the free board part 3b even with the normal temperature gradually turns to be high temperature air by receiving heat from the inner wall of the incinerator or of the exhaust gas passage due to the large heat capacity of refractory material until the air reaches metal surface, resulting in replacing the exhaust gas with the air while the temperature of the metal surface keeps a high temperature of 70W120°C or above and accordingly in enabling to prevent the bedewing onto the metal surface and yet the low temperature corrosion from occurring.

Abstract: PURPOSE:To feed materials to be incinerated of a certain size or smaller smoothly at a constant rate by an arrangement in which the space between a movable wall and a screw shaft when the movable wall moved away from the shaft farthest is controlled not to be smaller than the distance from the top of the entrance of the opening in which the screw shaft and movable wall are housed. CONSTITUTION:When materials to be incinerated slide down a feed hopper 9 to enter into a screw device 1a, the materials of a size up to the equivalent of a space D' between the inner surface of a movable wall 7b and the outer perimeter of a screw shaft 4 can freely enter between screw blades 5, if the movable wall 7b is situated at the innermost position. When materials of size D enter between the movable wall 7b and screw shaft 4, the pressure on the movable wall 7b becomes excessive. As a result, the movable wall 7b moves against the pressure of support cylinders 10, 10' back to a position shown by double dot-dash lines. Then, those materials to be incinerated are fed in the axial direction of the screw shaft 4, and are shaked off into a disposal chute 17 by a vane 12 of a shake-off device 1b.
