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 O2 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.

摘要： A combustion control method for refuse incinerators stabilizes a burning state to generate a predetermined amount of steam in a refuse incinerator which makes use of heat of combustion for steam power generation. The method comprises determining a weight of refuse charged and a level change before and after the charging of refuse from measurements of a refuse load cell attached to a refuse charging crane and a refuse level meter (12), which measures a surface level of refuse in a refuse incinerator hopper, to control a speed of a drying fire grate (3a), which serves to feed refuse into the incinerator, based on a result of comparison between quantities determined in a plurality of preceding charges and the quantities determined at the present time. Also, the method comprises measuring a quantity of steam generated in the refuse incinerator and an O2 concentration in an exhaust gas, calculating a target quantity of combustion air required for having the generated steam quantity agree with a target quantity of steam generated, setting a target quantity of combustion air, when a measurement of O2 concentration in the exhaust gas first reaches a predetermined upper limit value, as a temporary set quantity of combustion air, controlling a quantity of combustion air so as to have the same agree with the target quantity of combustion air when the measurement of O2 concentration in the exhaust gas is equal to or less than the upper limit value, and controlling a quantity of combustion air so as to have the same agree with a smaller one of the target quantity of combustion air at that time and the temporary set quantity of combustion air when the measurement of O2 concentration in the exhaust gas exceeds the upper limit value.

摘要： PROBLEM TO BE SOLVED: To shorten an adjustment period in the operation of a refuse incinerator, and to reduce the load of persons who carry out adjustment by obtaining a target remaining amount of refuse based on past operation result data. SOLUTION: In this method for determining the target remaining amount of refuse in an incinerator that burns refuse 3 while the remaining amount of the refuse is maintained constantly on a combustion fire lattice 5, the average value of vapor flowrate of vapor being generated by an exhaust gas being generated by the incineration of the refuse 3 in an operation cycle immediately before is obtained, and a negative correction value being set based on the average value of vapor flow rate and a target vapor flow rate is added to the target remaining amount of the refuse being set in the operation cycle immediately before when the average value of vapor flowrate is larger than the preset target vapor flowrate. On the other hand, when the average value of vapor flowrate is smaller than the target, a positive correction value being set based on the average value of vapor flowrate and the target vapor flowrate is added, thus calculating the target remaining amount of the refuse of the next operation cycle.
