Abstract

A burner apparatus for a furnace system and a method of burner operation. The burner has a series of fuel ejection structures which at least partially surround the burner wall for ejecting fuel into a combustion region projecting from the forward end of the burner wall. The ejection structures preferably eject fuel outside of the burner wall at alternating angles. Further, the burner apparatus preferably includes at least one additional series of fuel ejection structures which is spaced radially outward from the first series of ejection structures.
