LOW POLLUTION BURNING METHOD USING CO, NOX INDIVIDUAL CONTROL TYPE

摘要

The present invention relates to a waste gas emission control method, and particularly relates to a waste gas combustion method for reducing CO and NOx by combusting the waste gas by means of an individual CO and NOx control method. The present invention provides a low-pollution combustion method using an individual CO and NOx control method, comprising: a waste gas inflow and flame jetting step in which the waste gas is made to flow into a first combustion zone where a fuel obtained by pre-mixing a combustible gas and a combustion-support gas is ignited to produce a flame; a first waste gas combustion step in which the waste gas is combusted in the first combustion zone by being brought into contact with the flame produced by igniting the fuel gas obtained by pre-mixing the combustible gas and the combustion-support gas; and a second waste gas combustion step in which uncombusted components (CO, CH_4) remaining in the waste gas that has passed through the first waste gas combustion step and moved into a second combustion zone are induced to completely combust by being combusted in the second combustion zone together with a combustion-support gas that additionally flows into the second combustion zone.
