    摘要： A method of decreasing the concentration of nitrogen oxides in a combustion flue gas in which a nitrogen reducing agent is introduced together with the overfire air to mixes with the products of primary combustion along with the overfire air. The nitrogen agent reduced NOx as it passes through the temperature regime that is optimum for the NOx reduction as overfire air and flue gas mix. The transition from low to high temperature effectively eliminates ammonia slip. Additionally, the nitrogen agent may be mixed with the overfire air stream in such a manner that it is optimally shielded from early mixing with the products of primary combustion, where a portion of the overfire air reacts initially with any residual carbon monoxide (CO) that would otherwise interfere with the NOx reduction chemistry.

    摘要： Methods and systems for reducing nitrogen oxides in combustion flue gas is provided. The method includes combusting a fuel in a main combustion zone such that a flow of combustion flue gas is generated wherein the combustion flue gas includes at least one nitrogen oxide species, establishing a fuel-rich zone, forming a plurality of reduced N-containing species in the fuel rich zone, injecting over-fire air into the combustion flue gas downstream of fuel rich zone, and controlling process parameters to provide conditions for the reduced N-containing species to react with the nitrogen oxides in the OFA zone to produce elemental nitrogen such that a concentration of nitrogen oxides is reduced.
