Abstract
Apparatus and method for reducing NOX emissions from furnace flue gas are provided in which a stream of natural gas or other fluid fuel which has little or no fixed nitrogen is introduced into the upper portion of the furnace. The fuel stream has sufficient turbulence to form eddies surrounded by the flue gas so that the fuel reacts with the nitrogen oxides in the flue gas to form ammonia-like and cyanide-like compounds and nitrogen gas. The ammonia-like and cyanide-like compounds react with additional amounts of nitrogen oxides in the flue gas to form nitrogen gas, water vapor and carbon dioxide.
In this manner, the amount of nitrogen oxides in the flue gas is reduced. The invention can be easily applied to new furnaces or retrofitted on existing furnaces.
