The liquid fuel combustion device according to this invention uses a pump to pump liquid fuel into a constant oil level vessel, and an orifice at one end of the liquid fuel according to the air pressure acting on the oil level of the liquid fuel pumped into the oil level vessel. In the liquid fuel combustion apparatus, the liquid fuel is immersed in the liquid fuel in the leveler, and the liquid fuel is injected into the vaporizer through a fuel pipe whose other end has a fuel nozzle facing the vaporizer. The upper end surface of the surface defining wall is configured to have the lowest portion on the side closer to the fuel nozzle portion.
