Abstract
An oil fired burner adapted to produce a variable asymmetrical flame shape. The burner includes a tip head carrying a plurality of tips disposed in at least two orientations, i.e., axial and off-axis. The relative rates of fuel supply to the tips is controlled to afford asymmetric flame shaping. In a typical application in a rotary cement kiln, the flame is biased to increase the heat transferred to the load in the front end of the kiln and to decrease the heat transferred to the top and sides of the kiln.
