PURPOSE: To make a solid form of collected ashes in a short period of time without decreasing an effect of reducing a volume of ashes and without using any cement and to prevent the ashes from being formed into lump by a method wherein powder particles of calcium compound is mixed with an incinerator or its discharged gas, the incinerated ashes including the mixed powder particles are collected from the incinerated discharged gas and the collected incinerated ashes are humidified to form a solid.
CONSTITUTION: A desired amount of particle dolomite 11 of calcium compound is mixed in a refeeding circulation passage of fluidized sand by a feeding amount adjusting unit 12 and then fed into the incinerator 1 together with the fluidized sand. Either powder of CaO or CaCO2 thus generates is flown up from the fluidized bed 2 together with the ignited adhes, CaCO2 powder becomes CaO under hot temperature or a fire or combustion discharged gas, discharged out of the incinerator 1 together with the combustion discharged gas, its temperature is decreased by a gas cooling equipment 13 and almost all the adhes are collected by a dust removing equipment 14. The incinarated ashes discharged and accumulated in an ash banker 24 can turned into solidified ashes by means of particle formation or molding by a particle forming machine 16 and only by humidifying with an ash humidifying machine 15 without mixing cement or something like that.
