摘要： A METHOD OF TREATING NITROGEN OXIDE GENERATING SUBSTANCES BY COMBUSTION IN A REDUCING FLAME ATOMPHERE WHICH HAS THE STEPS OF INTRODUCING THE SUBSTANCE WHICH GENERATES NITROGEN OXIDE BY COMBUSTION, SUCH AS AMMONIA, HYDROGEN CYANIDE OR OTHER NITROGEN CONTAINING GASES OR A MIXTURE OF THESE GASES, INTO A HIGH TEMPERATURE REDUCING FLAME PRODUCED BY THE COMBUSTION OF FUEL GAS CONTAINING HYDROGEN, CARBON MONOXIDE A GASEOUS HYDROCARBON AN MIXTURE THEREOF, WITH A PRIMARY AIR SUPPLIED IN AN AMOUNT BELOW THE AMOUNT OF AIR THEORETICALLY REQUIRED FOR COMBUSTION OF THE FUEL GAS WHEREBY THE GENERATED NITRIGEN OXIDES ARE REDUCED TO NITROGEN IN THE HIGH TEMPERATURE REDUCING FLAME AND IF REQUIRED SUPPLYING A THIRD AIR TO THE RELATIVELY HIGH TEMPERATURE PORTION OUT OF THE FLAME THEREBY BURNING ANY UNBURNED COMPONENTS.
