    摘要: A system and method for reducing NOx emissions from a lean burn combustion source is provided. The system includes a blower passing air through a continuous duct having a hot portion and a reaction portion. The hot portion of the duct is positioned in the convective zone of the combustion source to heat the passing air for the reaction portion of the duct. An injector attached to a urea storage container is positioned in the reaction portion of the duct and sprays urea from the storage container into the heated air in the reaction duct for evaporation and decomposition into ammonia gas. The ammonia gas is then supplied to an injection grid in the exhaust duct of the lean burn combustion source upstream of a NOx reduction catalyst. The injection grid supplies the ammonia gas to the exhaust gas in the exhaust duct.
