PURPOSE:To prevent a flame tray from being deformed by heat, by bringing the flame tray into close contact with a flame cylinder by interposing a packing material between the flame tray and the bottom edge of a flame cylinder. CONSTITUTION:Fuel evaporated from a wick 11 is mixed with the air flowing into a flame cylinder 14 from air holes 13, rising along the inside wall of a flame cylinder 14 while burning, and is exhausted from the top of it. At the time of combustion, the flame cylinder 14 is heated up to high temperature of 600-800 deg.C, but the heat is not directly transferred to a flame tray 12, instead it is insulated by a packing 19. With this arrangement, the flame tray 21 is prevented from being deformed by heat, and a kerosene burner can be used with its horizontal posture being kept. Any gap which may be produced between the flame tray 12 and the flame chamber 14 by strain or crack during work can be filled with and sealed by the packing 19. Thereby abnormal combustion caused by excess air flowing into the flame chamber 14 from the gap can be prevented. |
