FLUIDIZED BED INCINERATOR

摘要

In order to circulatingly move a fluidized bed material S on a substantially horizontal plane without providing a partition and to carry out a slow combustion at a low fluidization velocity, especially in a dry thermal decomposition zone, an inclined bed wall (6) of an incinerator body (1) is extended from the side of a charge port (4) in the downward direction to the lower side of an ash discharge port, and the portions of left and right side walls (1c, 1d) which are on the side of the charge port (4) of the incinerator body (1) are formed as inclined side walls (24R, 24L) the upper portions of which are inclined toward a central portion of the incinerator body so as to guide the fluidized bed material S blown up from side fluidized beds RS, LS to a central fluidized bed CS, whereby the fluidized bed material S is circulatingly moved from the central fluidized bed CS on the side of the charge port (4) to the central fluidized bed CS on the side of the ash discharge port (5), side fluidized beds RS, LS on the side of the ash discharge port (5), side fluidized beds RS, LS on the side of the charge port (4) and central fluidized bed CS on the side of the charge port (4) in the mentioned order by the distribution air ejected from distribution air pipes (21A, 21B, 25).
