Patent ID: 7585170

Claim:
A combustor for combusting animal and vegetable oils, the combustor comprising; a burner tile having a first end and a second end opposite the first end, a burner nozzle, means for supplying animal and vegetable oils through the burner nozzle, into the burner tile in the form of atomized fuel, means for introducing a straight-line air current into the burner tile, which straightly flows in a vicinity of the burner nozzle from the first end to the second end of the burner tile at which there is an opening of the burner tile by operation of a blower, the straight-line air current flowing straightly through a central portion of the burner tile from the first end to the second end such that the straight-line air current extends through an entire region through which combustion occurs, and means for forming a field of centrifugal force surrounding the straight-line air current within the burner tile by the effect of a turning air current, which is introduced into the burner tile from an opening end connected substantially tangential to an inner surface of a sidewall of the burner tile by operation of another blower, fuel droplets of the atomized fuel being separated, taking various orbits in line with respective masses of the fuel droplets within the field of the centrifugal force, and being combusted.
