PURPOSE:To make it possible to vaporize liquid fuel rapidly and surely by fitting a cylindrical heater core into a cylindrical body provided with heat receiving fins on the outer circumferential face and forming a fuel flow passage in the heater core and mounting a vaporized fuel exhaust pipe at the one end of the cylindrical body. CONSTITUTION:Electric current supply is passed through the resistance wire of a heater coil 4 to heat a cylindrical heater core 3 and at the same time a liquid fuel is supplied from a fuel introduction pipe 9. The liquid fuel is led to a fuel flow passage 8 from a fuel flow hole 13 through a liquid fuel introduction opening 14 of the liquid fuel introduction pipe 9, and it contacts the heated heater core to be vaporized. Next, the vaporized fuel generated from the liquid fuel passes through a vaporized fuel injection pipe 6 from a vaporized fuel injection section 15 and is injected from an injection opening 7 into the vaporization chamber of a burner. When the combustion in the combustion chamber has fully progressed, the electric current supply to the heater coil 4 is stopped. After this the liquid fuel is vaporized by the radiation heat which heat receiving fins 5 have received from the combustion chamber. |
