PURPOSE: To prevent partial combustion, by arranging pipe grids by mounting nozzles to the lower surfaces of pipes that the outer diameter of the pipes and clearance among the pipes are set to specified dimension ranges, to make the fluid of a fluid layer and the passage of burnt residue uniform and smooth.
CONSTITUTION: In a fluid layer incinerator 1 that matters to be burnt 12 are burnt in a fluid layer 2, the unburnt solid matters are collected to the upper portions of pipe grids 3 by the difference of s.g. while a movable layer 4 consisting of a fluid medium and the unburnt solid matters is shaped to the lower portions of the pipe grids 3, and the content of the movable layer 4 is taken out by means of a double damper 7 and sieved by means of a sieve device 8, said pipe grids 3 are arranged in such a manner that nozzles 13b are mounted to the lower surfaces of pipes 3b that the outer diameter D of the pipes is set to 25.4W254mm and distance E among the pipes to 25.4W101.6mm respectively. Thus, combustion efficiency can be improved by a simple arrangement
