PURPOSE:To effect complete combustion of unburnt fuel due to a generation of eddy at the inside of an outer cylinder by a method wherein an outer cylinder formed an opening hole on a tip surface is installed to outer periphery of the tip section of a burner cover with predetermined intervals between the burner cover. CONSTITUTION:Air produced by a cirocco fan 4 is blown into the inside of the burner cover 1 through an air blow-off pipe 3, at the same time, liquid fuel is sprayed from the burner nozzle 2 of a center portion of the burner cover 1 and they are ignited by an ignition plug 5. The outer peripheral portion of flame, moves forward along the inner peripheral surface of the outer cylinder 9 fitted to the outer periphery of the tip section of the burner cover 1, and heats the outer cylinder 9, thereafter, it is injected from the opening hole 11 formed on the tip surface, then, a violent eddy generates at the tip portion of the outer cylinder 9. As a result, the unburnt fuel is vaporized into the eddy and may be effected complete combustion.
