PURPOSE:To easily adjust the heating power and at the same time completely burn at all times even under low heat and yet prevent an ignition plug from being fouled with soot by a method wherein secondary fuel impregnated in an oil-impregnating body is evaporated by heating the oil-impregnated body with the flame of primary combustion and jetted from through holes of an inner cylinder so as to mix with secondary air. CONSTITUTION:Primary air is supplied in a cylinder 38 and at the same time fuel such as heavy oil or the like is supplied through an oil feed pipe 22 so as to drip from a primary fuel supply pipe 24 and an oil drip feed pipe 44 in order to impregnate in an oil impregnating body 4. When an ignition plug 5 is actuated under the above-mentioned state, primary combustion occurs in a primary fuel hole 45. When the amount of fuel supplied to the oil feed pipe 22 under the conditions as just mentioned above, fuel overflowed the primary fuel supply pipe 24 is dripped through a secondary fuel supply pipe 23 so as to be supplied at the upper part of the oil-impregnating body 4 to impregnate the body 4 with. Because the oil-impregnated body 4 is heated up to high temperature with the flame of the primary combustion, the secondary fuel dripped through the pipe 23 is heated and evapoated and jetted in the through holes 40, vertical holes 41 and lateral holes 42. |
