摘要: A combustion control method for waste incinerators, developed for the purpose of reducing the concentrations of CO and NOx in a waste gas and a generation rate of dioxine. The condition of the waste on a post-combustion fire grate (3c) is judged on the basis of measurement values on a main flue thermometer (14), an O 2 analyser (16), a CO concentration meter (17) and a barometer (18a) which is set under the post-combustion fire grate. Thus, the possibility that the apparatus will get into an insufficient temperature condition, or an air or fuel shortage condition is judged quickly, and the flow rate of the air to the post-combustion fire grate (3c), or the flow rate of the air to the same fire grate (3c) and the moving speed of the fire grate are controlled.
