Abstract

PURPOSE:To perform gas phase decomposition reaction of NOx with high efficiency by mixing and pouring a reducing agent into a portion of the gases extracted from a combusion zone in a furnace or other portion extracted from the combustion zone in a furnace or other portion to rapidly and qucikly mix a small amount of the reducing agent with the exhaust gases.
