PURPOSE:To enable to maintain favourable evaporating combustion over a lang period of time by a structure wherein a red hot plate is positioned at the front side of the flat surface of an evaporating body with an heat insulating space between said red hot plate and said flat surface in order to maintain said evaporating body at the temperature suitable for the production of evaporated gas. CONSTITUTION:The evaporating body 4, the tip of which is closed with the flat surface 5 and the basic end of which is open, is rotatably positioned in a combustion tube 1. The red hot plate 21 is positioned at the front side of the flat surface 5 of the evaporating body 4 with the heat insulating space 22 between the red hot plate 21 and the flat surface 5. Owing to the structure as mentioned above, because all the smoke produced by the excessive supply action of liquid fuel is adhered to the red hot plate 21 side and removed by being burnt there, the flat surface 5 at the tip of the evaporating body 4 is surely prevented from being adhered with smoke and as a result the evaporating body 4 is maintained at the constant temperature suitable for the production of evaporated gas at all times, resulting in maintaining favourable evaporating combustion over a long period of time. |
