COMBUSTION CONTROL METHOD FOR COMBUSTION CHAMBER OF WASTE MELTING TREATMENT FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a combustion control method for a combustion chamber of waste melting treatment facilities capable of performing complete combustion of rapidly increasing combustible dust in the combustion chamber by taking a current combustion air amount into consideration.

SOLUTION: The combustion control method for a combustion chamber 13 in which combustible gas and combustible dust discharged from a waste melting furnace 10 are burnt includes: calculating a determination value H for whether control output OP of the amount of combustion air supplied to the combustion chamber 13 needs to be corrected on the basis of the current value PV of the amount of combustion air; and adding a control output correction value ΔOP calculated according to a variation amount ΔPV of furnace top pressure and in-furnace difference pressure of the waste melting furnace 10 to the control output OP of the amount of combustion air, and blowing air into the combustion chamber 13 when the variation amount ΔPV is equal to or larger than the determination value H.
