The present invention is a combustion control method of a waste incinerator for the purpose of reducing CO, NOx concentration, dioxin and the like in flue gas. For this purpose, the state of the garbage on the post combustion grate 3c is judged on the basis of the measurement values of the main flue thermometer 14, the O2 densitometer 16, the CO concentration meter 17, the barometer 18a under the post combustion grate, The tendency to fall into a state of lack of temperature, lack of air, or lack of fuel is quickly determined to control the amount of air to the afterburning grate 3c or the amount of air to the afterburning grate 3c and the same speed of the afterburning grate. |
