PURPOSE:To improve the firing plug and improve combustibility by opening an opening on one side at the bottom face portion of a combustion space and opening in a receiving space an opening on the other side which communicates with the opening on one side to form a passage and directing the passage to the firing plus and supplying part of the air for combustion to the passage. CONSTITUTION:When the air for combustion is supplied by a fan with a fan motor 48 and a liquid fuel is supplied through a fuel oil feeding pipe 14 rotated by a motor 16, the fuel is injected out into the combustion space 22 through the outer circumferential mixture gas passages 24 and 26. When sparks are created by a firing plus 10, the mixture gas is fired. At this time, part of the air for combustion is supplied toward the firing plus 10 through a passage 44 to make the fired flame larger, with a result of improved firing by preventing soot adherence. Vaporized fuel is injected into the combustion space 22 with the air for combustion and continues its combustion. Since during the continued combustion, the air for combustion is supplemented as a secondary air to the combustion space 22 from a plurality of passages 44, combustibility can be improved.
