Abstract

PURPOSE:To raise the capability by improving the kerosene diffusion means and thermal conductivity in the carburetor. CONSTITUTION:A primary inclining vaporization section 18 is provided above a carburetor 16 and it projects towards the side of a burner head 15. A secondary inclining vaporization section 19 is provided below the carburetor 16, and on its surface a plurality of diffusion grooves 20 are provided which extend almost horizontally. The kerosene which has not vaporized in the primary inclining vaporization section 18 flows down on the surface of the secondary inclining vaporization section 19 and enters the diffusion grooves 20, and it is diffused widely on the surface of the secondary inclining vaporization section 19. And, since the kerosene, when it enters the diffusion grooves 20, has its flow disturbed, its heat conductivity is improved. Because of the above two reasons the capability of vaporization of the secondary inclining vaporization section 19 is raised, and the kerosene which has not vaporized in the primary inclining vaporization section 18 is vaporized here surely.

Next, the combustion operation will be explained. combustion fan 1
The air sent from the burner head 2 is divided into two systems: vaporized air flowing into the vaporizer 4 from the vaporized air inlet 7, and secondary air ejected from the burner head 2. Further, the kerosene ejected from the oil feed nozzle 10 collides with the inclined vaporizer 5 and vaporizes, and the vaporized gas generated here mixes with the vaporized air to form a premixture, which is ejected from the burner head 2 and ignited. The discharge of electrodes (not shown) ignites and starts combustion, which is further promoted by secondary air. Then, when the combustion heat received by the heat receiving part 11 is thermally conducted to the vaporizer 4,
The temperature of the inclined vaporization section 5 is controlled so that the temperature approaches the set temperature, and at the same time, the heater 3 is turned on and off so that the temperature of the inclined vaporization section 5 reaches the set temperature.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional configuration, deteriorated kerosene is supplied from the oil feed nozzle 10, and tar adheres to the surface of the inclined vaporizing section 5, reducing the vaporizing ability of the inclined vaporizing section 5. In this case, the supplied kerosene may not be completely vaporized in the inclined vaporizing section 5. in this case,
Kerosene flows from the inclined vaporization section 5 to the vertical vaporization section 6, but in the vertical vaporization section 6, kerosene and vaporized air flow in the same direction, so this vaporized air has little effect of pushing and spreading the kerosene.
The kerosene flows down the surface of the vertical vaporizer 6 in the form of a band. That is, the surface of the vertical vaporizing section 6 provided for vaporizing kerosene does not function sufficiently and has a small vaporizing ability, resulting in a problem in that the kerosene flowing thereon suffers from poor vaporization.

[Operation] With the above structure, when the kerosene that has flowed from the primary inclined vaporization section to the secondary inclined vaporization section attempts to flow down the surface of the secondary inclined vaporization section, it enters the diffusion groove and flows along the diffusion groove. It flows horizontally and spreads widely on the surface of the secondary inclined vaporization section while further flowing down. That is, the kerosene spreads over a wide area on the surface of the secondary inclined vaporization section and is reliably vaporized there.

Next, the combustion operation will be explained. Air supplied from the combustion fan 26 flows into the lower part of the air chamber 27, and is then supplied to the primary inclined vaporizer 18 and the burner head 15 through the vaporized air inlet 22 and the oil feed nozzle inlet 25. It is divided into two systems of secondary air. In particular, the vaporizing air supplied from the vaporizing air inlet 22 impinges on the lower part of the primary inclined vaporizing section 18 and rises along this primary inclined vaporizing section 18 . Further, the kerosene ejected from the oil supply nozzle 24 collides with the upper part of the primary inclined vaporizing section 18 and is diffused, and is pushed and spread over a wide range of the primary inclined vaporizing section 18 by the vaporizing air, so that it is instantaneously vaporized. The generated vaporized gas is mixed with the vaporized air in the mixing chamber 14 and sent to the burner head 15 where it is combusted together with the secondary air.

Further, when the combustion heat received by the heat receiving section 21 is thermally conducted to the vaporizer 16, the temperature of the primary inclined vaporizing section 18 approaches the set temperature, and at the same time, the heater 17 is turned on and off, and the temperature of the primary inclined vaporizing section 18 reaches the set temperature. The temperature is controlled. That is, since the combustion heat is recovered by the heat receiving section 21, the frequency of use of the heater 17 is reduced, and the electricity bill can be reduced.

Next, deteriorated kerosene is supplied from the oil feed nozzle 24, or tar adheres to the surface of the primary inclined vaporizer 18, reducing the vaporization ability of the primary inclined vaporizer 18. A case where the vaporization section 18 cannot vaporize all of the liquid will be described. In this case, the kerosene flowing from the primary inclined vaporization section 18 to the secondary inclined vaporization section 19 is
, and enters the diffusion groove 20 . Thereafter, the kerosene flows horizontally along the diffusion groove 20 and falls again, where it is widely diffused on the surface of the secondary inclined vaporization section 19. Further, when the kerosene enters the diffusion groove 20, the flow is disturbed, so that the heat transfer coefficient increases and the vaporization ability of the secondary inclined vaporization section 19 is improved. That is, since the kerosene spreads over a wide range on the surface of the secondary inclined vaporization section 19, the surface of the secondary inclined vaporization section 19 can sufficiently exhibit its vaporization function. Therefore, the kerosene that was not vaporized in the primary inclined vaporization section 18 is reliably vaporized here due to the vaporization ability of the secondary inclined vaporization section 19.

[Effects of the Invention] As described above, the oil combustion apparatus of the present invention provides the following effects. (1) Since a diffusion groove formed in a substantially horizontal direction is provided in the secondary inclined vaporization section, even if the supplied kerosene is not completely vaporized in the primary inclined vaporization section, the kerosene will be absorbed by the surface of the secondary inclined vaporization section. It has the effect of spreading and vaporizing over a wide area. (2) When kerosene enters the diffusion groove, the flow is turbulent, so the heat transfer coefficient increases and the vaporization ability of the secondary inclined vaporization section improves.
