ABSTRACT:
A vortex burner includes a first feed pipe and a second feed pipe disposed within the first feed pipe. A first set of gas distribution tubes extends from an end of the first feed pipe and extends towards a radiant cup portion of the vortex burner. Also, a second set of gas distribution tubes extends from the second feed pipe also toward the radiant cup portion of the vortex burner. A first fuel gas is capable of flowing through a portion of the first feed pipe not occupied by the second feed pipe, i.e. an annulus area of space, and through the associated first set of gas distribution tubes. A second fuel gas, of either a higher or lower Wobbe index than the first fuel gas is capable of flowing through the second feed pipe and its associated second set of gas distribution tubes. Thus, the vortex burner is capable of burning either high or low Wobbe fuel gases. The first and second fuel pipes may also be separately disposed within the vortex burner.
