FLUIDIZED BED INCINERATOR FACILITY AND METHOD OF CONTROLLING COMBUSTION OF FLUIDIZED BED INCINERATOR FACILITY

摘要

PROBLEM TO BE SOLVED: To instantaneously adjust the quantity of supplied waste, based on the detection, by detecting the fluctuation of the quantity of supply of waste to the fluidized bed incinerator body in earlier stages than its secondary combustion. ;SOLUTION: Waste 3, which is sent out with a screw feeder 21 and slips down within a chute 29 for supply and is cast in a fluidized bed 5 within a fluidized bed system of incinerator body 2 from a waste charge port 9, is dried and thermally decomposed in a drying and thermal decomposition zone, and then it is primarily combusted in primary combustion zone 18, and further in the process of secondary combustion in a secondary combustion chamber 6, the quantity of light, which enters the chute 28 for supply, passing through the waste charge port 9 from the drying thermal decomposition zone 17, is measured with a quantity-of-visible light measuring device 36, and in the case that the measured quantity of light is specified one quantity or less, the feeding velocity of the screw feeder 21 is reduced, and in case that the measured quantity of light is over the specified one, the feed velocity of the screw feeder 21 is increased.;COPYRIGHT: (C)1999,JPO
