PURPOSE:To enable a stable flame formation independent from changes of combustion rate by a method wherein a combustion cylinder is divided in the vertical direction by a ring-shaped disc, with the diameter of the lower cylinder smaller than that of the upper cylinder. CONSTITUTION:Above a vaporization chamber wherein liquid fuel is vaporized, an outer cylinder 2 is provided, and within the outer cylinder 2, a bottomed combustion cylinder 3 is provided. The combustion cylinder 3 has a side peripheral surface of metallic net or punched member and the ring-shaped disc 5 which divides the combustion cylinder 3 into two parts in the vertical direction. The ring-shaped disc 5 has a flame port 4 in the center. In this instance, the lower cylinder 3' is designed to have a smaller diameter than the upper cylinder 3. By this, the stable flame can be formed independent from the changes of the combustion rate. Further, the rising of flame temperature can be prevented, the combustion can be stabilized, the combustion gas can be maintained to be clean, and the generation of NOX can be effectively reduced. |
