ABSTRACT:
A fluidizing gas control apparatus for a fluidized-bed incinerator, in which a variation of the pressure loss of fluidizing gas flowing through a fluidized bed formed by a fluid-forming medium is measured, while progressively increasing the flow rate of fluidizing gas supplied to the incinerator in the starting stage, to determine the optimum value of the flow rate of fluidizing gas on the basis of the measured variation of the pressure loss, and the sum of the flow rate of fluidizing air and the flow rate of recirculated gases provided by recirculation of a portion of exhaust gases is controlled to be maintained at the optimum flow rate throughout the incinerating operation of the incinerator.
