Abstract
A system for the reduction of nitrogen oxides in the effluent from the combustion of a carbonaceous fuel is presented. This system utilizes means for determining the lowest achievable nitrogen oxides concentration with respect to a treatment agent to be introduced into the effluent; means for determining whether the baseline nitrogen oxides concentration at the point of introduction is above the lowest achievable nitrogen oxides concentration; and means for introducing the treatment agent into the effluent under conditions effective to reduce the effluent nitrogen oxides concentration.
