METHOD OF CONTROLLING COMBUSTION OF FLUIDIZED-BED INCINERATOR

PCT No. PCT/JP91/00399 Sec. 371 Date Nov. 25, 1991 Sec. 102(e) Date Nov. 25, 1991 PCT Filed Mar. 27, 1991 PCT Pub. No. WO91/14915 PCT Pub. Date Oct. 3, 1991.The present invention discloses a method of controlling combustion of a fluidized-bed incinerator. In a fluidized-bed incinerator (5), a method of controlling combustion of the fluidized-bed incinerator comprises measuring a supply rate of incineration waste by a supply rate measuring unit (11) using a photoelectric element (1) arranged on a shoot (2) for supplying incineration waste (3) from a dust feeder (4) to the incinerator (5), and when the supply rate of incineration waste is higher than a predetermined value, decreasing a supply rate of incineration waste of the dust feeder 4 to suppress a combusting operation, increasing an induced gas rate of an exhaust gas induced blower (9) of the incinerator to suppress an increase in an incinerator internal pressure decreasing a flow rate of fluidizing air of a forcing blower (7) to suppress a combusting operation, or increasing a flow rate of a blower (8) for supplying air to a free board portion to prevent production of an unburnt gas.
