ABSTRACT:
In a method of reducing NO.sub.x a water-fixed nitrogen solution is injected into a furnace near the exit from the furnace where the temperatures exceed 2000.degree. F. and combustion is occurring. Preferably the solution is injected through a combination of atomizing nozzles and spray jets into a region of the furnace which does not exceed 2700.degree. F. A calcium compound to react with sulfur dioxide may also be added.
