method for combining of oxidant and fuel in an oxygen fuel burner for fuel and oxidant koaxialem outlet

摘要

An oxy-fuel burner includes an outer oxidant tube (12), an intermediate fuel tube (14) and an inner oxidant tube (16) which are coaxially arranged with the fuel tube disposed between the inner and outer oxidant tubes. Characteristics of the flame produced by the burner may be controlled by varying the relative flow rates of the inner and outer oxidant flows. An increase in the percentage of the total oxidant which is provided to the inner oxidant tube causes the length and luminosity of the flame to decrease and the flame momentum to increase. The characteristics of a burner flame can be tailored to a particular application without requiring mechanical modification of the burner.
