XOTHERMIC INC. developed an oxygen burner configuration that produces a truly adjustable flame length and luminosity. The burner's given rating is the mid range of the burner or the nominal rating. These burners have a 4:1 turndown. At nominal rating the burner has the greatest flame adjustment. This is achieved by opening or closing the secondary oxygen balancing valve. This either adds oxygen to the secondaries, thus increasing flame length and luminosity, or subtracts oxygen to the secondaries, thus reducing flame length and luminosity. This is without changing the firing rate. Typically, the flames length at the nominal rating can be increased by 50%. This burner has applications in the Ferrous, non-Ferrous and Ceramic Industries.
