This patent describes a method for purifying gaseous combustion products by reducing the NO/sub x/ content thereof by contacting a stream of hot gaseous combustion products with a reducing agent that effects a chemical reaction which reduces the NO/sub x/ content by at least partial conversion to Nâ. The reducing agent is ammonia, a precursor of ammonia or a mixture thereof in vapor or vaporizable form.
