ABSTRACT:
Nitrogen oxide and dioxide content of flue gas from combustion devices is reduced by mixing combustion air and a gas or volatilized fuel in proportions below the lower combustible limit of the mixture and utilizing that mixture for at least a part of the combustion air supplied to the devices. The mixture may take the form of air contaminated with a fuel.
