A case s tudy of a campus waste incineration facility operation

摘要

Air controlled pyroysis of campus wastes was conducted in the first combustion chamber of the incineration system. Excess air w as used in the secondary combustion chamber to ensure a complete combustion of combustibles and hazardous substances formed in the pyrolysis. Heat revoered from the waste heat boiler was utilized for soludge drying and waste gas preheating. Venturi and packed bed scrubbers were used in emission controls. Particulates, NO_x, and SO_x in flue gas were closely monitored for emission quality evlauation. Data of SEM/EDX of bioler tubes reveal that an electrochemical corrosion occurred in the waste gas cooling system.
