TEST OF A PREMIXING RADIANT BURNER FOR THE LOW NOX COMBUSTION OF NATURAL-GAS HYDROGEN MIXTURES

The subject of this work is the development and testing of premixing r adiant burners operated either with natural gas or natural gas contain ing different hydrogen fractions. Emphasis is first placed on establis hing a stable combustion process by varying the fuel gas composition, air ratio and burner load; furthermore, emissions should be as low as possible. With respect to flashback-free operation, it is important to define the limits of hydrogen addition for the burner concept develop ed.
