Abstract
A waste treatment technique includes: blowing a fluidizing gas from around a mixture discharge port to form a first fluidization region having a degree of fluidization of the fluidizable particles which is set to an extent allowing waste to be accumulated on fluidizable particles, while blowing a fluidizing gas between the first fluidization region and an opposite-side wall at a higher flow velocity to form a second fluid region having a degree of fluidization of fluidizable particles greater than that in the first fluidization region, whereby the fluidizable particles are mixed with the waste to gasify the waste; and supplying waste from a supply-side sidewall portion onto the fluidized bed to cause the waste to be accumulated on the first fluidization region while causing the accumulated waste to be moved into the second fluidization region step-by-step.
