Abstract (en)
[origin: EP2587146A1] Disclosed is a waste treatment technique characterized in that it comprises: blowing a fluidizing gas from around a non-combustible substance discharge port (29) toward fluidizable particles to form a first fluidization region (15), while blowing a fluidizing gas between the first fluidization region (15) and a front wall (24) at a flow velocity less than that in the first fluidization region (15) to form a second fluid region (16) having a relatively low degree of fluidization of fluidizable particles (12); returning fluidizable particles (12) discharged from the non-combustible substance discharge port (29) to a fluidized bed (14) from the side of the front wall (24) to form, in the fluidized bed (14), a flow of fluidizable particles (12) directed from the front wall (24) to the non-combustible substance discharge port (29); supplying waste (18) from the front wall (24) onto the fluidized bed (14) to cause the waste (18) to be accumulated on the second fluidization region (16) while causing the accumulated waste (18) to be moved into the first fluidization region (15) step-by-step and gasified.
