DEVELOPMENT AND DEMONSTRATION OF NOVEL LOW-NOx BURNERS …

2006/12/28 · When the laboratory burner/boiler was operated with 500 vppm ammonia in the fuel, NOx emissions ranged from 50 to 75 vppm. This, conservatively, is 75% less than state-of-the-art burner performance. When the burner is operated with 200 vppm ammonia in the fuel, the corresponding NOx emissions would range from 30 to 45 vppm, 84% less than present burner …

US5511971A - Low nox burner process for boilers - Google Patents

In some burners a simple cone structure placed in the burner provides additional flame stability. Process is described for reducing emissions of nitrogen oxides and carbon monoxide from fuel gas fired boilers by using a computer to closely control the flow rate of combustion air and by installing a duct to allow flue gas to recirculate into the air intake of the boiler.
