Abstract
A system and a method for controlling NOemissions from a boiler that combusts carbonaceous fuels. The method includes the steps of (a) introducing carbonaceous fuel and combustion air into a furnace of the boiler for combusting the carbonaceous fuel in oxidizing conditions and producing flue gas including NOand CO, and (b) leading flue gas from the furnace to a catalyst section in a flue gas channel for converting, free from introducing an external agent for NOreduction, NOto Nand CO to COby using CO as the reductant of NOon a catalyst in the catalyst section.
