焼の安定化を目的とする。Detailed Description of the Invention The present invention is used in oil water heaters, oil hot air blowers, etc., and is a vaporizer in which liquid fuel is atomized and sent together with air to a vaporization chamber, and the vaporized premixture generated there is combusted at a flame port. The purpose is to stabilize combustion in premix liquid fuel combustion devices.

保たれる。 As shown in FIG. 2, a conventional liquid fuel combustion apparatus of this type has a heater 1' provided in a vaporization container 2', and the vaporization container 2' has a vaporization surface 3' and a heat receiving surface 4'. The liquid fuel flowing down from the fuel supply pipe 6' by the pump 5' is scattered around by the rotating plate 7'. At this time, the vaporizing surface 3' of the vaporizing container 2' is sufficiently heated by the heater 1', and the scattered fuel particles collide with this vaporizing surface 3' to form vaporized gas, which is sent from the blower fan 8'. It is mixed with air and combusted in burner head 9'. After the combustion has stabilized, combustion heat is transferred from the heat receiving surface 4' heated by the combustion flame to the vaporizing surface 3' via the vaporizing container 2'.
The vaporizing surface 3' is maintained at a high temperature by conducting heat to the vaporizing surface 3'.
然るに、気化面３′と受熱面４′が離れているた

３の温度が十分に高温維持出来ず、気化熱不足か

を生じた。 However, since the vaporizing surface 3' and the heat receiving surface 4' are separated, a temperature difference occurs between the vaporizing surface 3' and the heat receiving surface 4', and the temperature of the vaporizing surface 3 cannot be maintained at a sufficiently high temperature, resulting in insufficient vaporization heat. This caused problems such as delays and generation of tar.
そこで、気化面３と受熱面４の熱結合を良くす

される。 Therefore, in order to improve the thermal coupling between the vaporizing surface 3 and the heat receiving surface 4, we considered increasing the cross-sectional area and raising the set temperature. ', the preheating time becomes longer, there are limitations such as an increase in weight and shape, and conversely, this is accompanied by an increase in heat dissipation. In addition, increasing the set temperature,
It is limited by the melting point of the material and the critical temperature of the heat receiving surface 4'.

５とタンクＴが接続されている。 The present invention aims to improve the above-mentioned problems by enclosing a substance that melts at a lower temperature than that of the vaporizing container, and using its latent heat of melting and fluidity to improve the conductivity of the vaporizing surface and the heat-receiving surface. One embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of an embodiment of the present invention, in which a burner head 9 is provided on the upper part of a vaporizing vessel 2, and a heat receiving surface 4 is formed near the burner head 9. On the other hand, a heater 1 is buried in the lower part of the vaporization container 2, and a passage 11 through which fuel and air flow is provided on the side surface of the vaporization container 2. The vaporization container 2 is made of Al, Cu, Fe, etc., which have good thermal conductivity, and encloses therein a heat conductor 10 made of a material that melts at a lower temperature, such as Zn, Sn, wax, etc. A blower 8 and a nozzle 12 are communicated with the passage 11, and a pump 5 and a tank T are connected to the nozzle 12 via an oil supply pipe 6.

When preheated by the heater 1 to a suitable level, air is sent from the blower 8 and atomized liquid fuel is sent from the nozzle 12 to the vaporization container 2 through the passage 11, respectively.
The atomized liquid fuel entering from the passage 11 becomes vaporized gas at the vaporization surface 3, mixes with the air, and burns at the burner head 9, forming a flame 13.

で対流が良くなる。 During preheating, the heat generated by the heater 1 is transferred to the vaporization container 2.
to heat the vaporization surface 3, but the heat conductor 10
When the temperature exceeds the melting temperature of , the thermal conductor 10 liquefies and heats the vaporizing surface 3 by convection as well as conduction.
During steady combustion, the heat receiving surface 4 is heated by the heat of the flame 13, and the vaporization surface 3 is cooled by liquid fuel. When the heat receiving surface 4 reaches a certain temperature or higher, the heat conductor 10 melts due to the heat and receives heat. Convection flows between the surface 4 and the vaporization surface 3, and thermal coupling is performed by convection and heat conduction, and the heat receiving surface 4
The combustion heat received at is efficiently transferred to the vaporization surface 3. As another example, the heater 1 is used as a heat conductor 1.
When the heat conductor 10 is provided within the temperature range, the melting time is shortened, and the temperature difference in the melted heat conductor 10 is accelerated, resulting in better convection.

Furthermore, since the generation of tar can be prevented, durability performance can also be improved.
