SCR reactant injection grid

摘要

A system and method of injecting an ammonia or urea reactant into a flue gas stream in a steam generating power plant that utilizes Selective Catalytic Reduction (SCR) to lower NOx emissions and more specifically the injection of the reactant in such a manner that a more uniform mixing of the reactant with the flue gas stream is achieved more rapidly thereby increasing the efficiency of the catalytic reduction process and further a method of increasing the amount of reaction that takes place between the reactant/flue gas mixture and the catalytic material.
