Abstract

A method of reducing NOx emissions from a lean burn combustion source employs an aqueous solution of reagent that is injected into a continuous decomposition duct at a rate of 0.2-10 gph with a flowing side stream of hot gas at a rate of 150-3000 scfm and a temperature of greater than 700° F. in the decomposition duct such that the aqueous reagent is converted to ammonia gas that is conveyed by the continuous decomposition duct to an ammonia injection grid that is placed in a primary exhaust stream from the combustion source upstream of a NOx reducing catalyst and NOx is reduced.
