| description | The present invention presents a combustion control method of a refuse incinerator for the purpose of decreasing CO, NOx concentration and dioxins in exhaust gas. Accordingly, on the basis of the measured values of principal flue thermometer, O2 densitometer, CO densitpmeter and NOx densitometer, the quantity of secondary combustion air is controlled so as to suppress the generation of NOx, and said quantity of secondary combustion air is adjusted in accordance with the O2 concentration for minimising the concentration of percursors of dioxins, whereby the concentration of precursors of dioxins is estimated from the mutual relation of the concentration of said precursors of dioxins and O2 concentration in said exhaust gas, so as to suppress the generation of dioxins in said exhaust gas. A combustion control apparatus of a refuse incinerator to carry out the control method according to the invention is also presented. |
