PURPOSE:To prevent tar adhesion to an inner drum, reduce foul odor generated just after fire extinction, and prevent oil gathering by a method wherein vaporized fuel guide plates installed in the inner surface of a burning cylinder are directed to an air cylinder and an inserted cylinder facing an opening part is installed at the inner drum and also a fuel atomization nozzle is placed in the inserted cylinder. CONSTITUTION:Revolving streams are formed in a vaporization domain 66 by spouting air from air holes 55A and oil atomized from a nozzle 61. As a result, vaporized fuel 67 starts to revolve and is going to rise up along the inner surface of a burning cylinder 56 by a centrifugal force. However, the fuel 67 is guided by vaporized fuel guide plates 59 to separate from the inner surface of the cylinder 56 and rises up along the outer wall of an air cylinder 54 and therefore, it is efficiently mixed with the spouting air to achieve perfect burning. As a result, circulating streams are formed by only burnt gas 68 and hence, tar adhesion to the inner wall of an inner drum 52 is prevented and also foul odor generated just after fire extinction is reduced.
