摘要： PROBLEM TO BE SOLVED: To provide a sludge fluidized bed incineration plant and a method for incinerating sludge, certainly preventing hot air in a furnace from being led to flow into a sludge supply portion while suppressing generation of greenhouse effect gas by raising combustion temperature.SOLUTION: This sludge fluidized bed incineration plant 1 includes: a furnace body 11 with the inside thereof as a combustion region; a main conveying section 21 having a conveying tube 22 communicating with the inside of the furnace body 11 and putting the sludge in the inside of the furnace body 11; a high water content sludge supply section 31 filling the inside of the conveying tube 22 with high water content sludge A1 as the sludge on the downstream side of the main conveying section 21, the high water content sludge having a high percentage of water content; and a low water content sludge supply section 32 supplying as the sludge, low water content sludge A2 having a lower percentage of water content than the high water content sludge A1, on the upstream side of the main conveying section 21 more than a position where the high water content sludge supply section 31 supplies the high water content sludge A1. The main conveying section 21 puts the sludge in the inside of the furnace body 11 from the conveying tube 22 in such an incompletely mixed state that the low water content sludge A2 conveyed from the upstream side is mixed in layers into the high water content sludge A1 supplied on the downstream side.
