Title:
COMBUSTION CONTROL METHOD FOR FLUIDIZED BED INCINERATOR
Document Type and Number:
WIPO Patent Application WO/1988/008504
Kind Code:
A1
Abstract:
A combustion control method for a fluidized bed incinerator in which a fluid medium is moved by the air, which is sent from the lower side of a fluidized bed into the incinerator, to burn an object fed thereinto, comprising the steps of detecting the combustion rate of the object burnt in the incinerator, by a combustion rate detecting means, and reducing when the combustion rate is not lower than a predetermined level the flow rate of the air sent from the lower side of the bed into the incinerator, and increasing the flow rate of the air blown into a space above the bed, whereby the combustion rate of the object burnt in the incinerator is maintained at the predetermined level to suppress the variations in the flow rates of the combustion air and exhaust gas, the concentration of oxygen in the exhaust gas and the quantity of unburnt gas. A combustion control method for a fluidized bed incinerator which has a plurality of air chambers at the lower side of a fluidized bed with the air sent into the incinerator through these air chambers, comprising the step of regulating the flow rate of the air, which is sent into the incinerator, by the air chamber which is in a position to which the object to be burnt being input to the incinerator falls, whereby the combustion rate of the object is controlled.
