ABSTRACT:
In a method for reducing NOx in the flue gas a coal water slurry is injected into the furnace above the primary combustion zone into a region having a temperature from 1800.degree. F. to 2700.degree. F. The slurry is preferably injected through atomizers and through injectors that introduce a continuous stream. Lime, ammonia, urea and completion air can also be injected.
