PURPOSE:To obtain stable combustion with good burning property continuously, by constituting a carburetor with double cylinders, and making the amount of secondary air passing the inner cylinder larger than the amount of the primary air, which is introduced in the carburetor. CONSTITUTION:A secondary air guiding path 11 comprises an inner cylinder, which pierces through the central part of a carburetor 5. Part of burning air, which is sent by a burning blower 10, is jetted through a primary air nozzle 9 as primary air A1. The most of the remaining air is guided to a secondary air guiding path 11 as secondary air A2 and jetted through a jetting plate 12. Kerosene, which is supplied to the carburetor 5, is atomized and vaporized by the primary air A1. The kerosene is mixed with the primary air A1 and sent to a flame hole part 13 and ignited. The kerosene burns together with the secondary air A2. At this time, the relation of (primary air A1 < secondary air A2) is set. Thus, the burning property, by which flame is hard to be extinguished, is obtained. Owing to the effect of the jetting plate 12, the secondary air A2 infiltrates into the flame, and very excellent burning property is obtained.
