As described above, the furnace of the present invention is characterized in that the gasification section is formed with a vertically hollow heating body equipped with a fuel heating source such as an electric heater around the gasification section, and with this point, This furnace has the extraordinary effect of promoting the gasification of fuel, quickly supplying the gasified fuel to the burner, and shortening the ignition time.

〔Example〕

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

Here, FIGS. 1 and 2 show an embodiment of the present invention, with FIG. 1 being a schematic configuration diagram and FIG. 2 being a partially cutaway perspective view.

Generally speaking, the furnace of this embodiment, like a conventional furnace of this kind, includes a burner section 1, a gasification section 2 for gasifying liquid fuel, and a gasification section 2 for supplying liquid fuel to the gasification section 2. The fuel supply section 3 includes a fuel supply section 3.

The burner section 1 is formed by a Bunsen burner 4, and includes an igniter 5, an electrode 6, and a flame rod 7 for ignition. A gasification section 2 is detachably connected to the rear end of the Bunsen burner 4.

The gasification section 2 is a place for gasifying liquid fuel, and is constituted by a vertically elongated hollow heating body 8 . The vertically elongated hollow heating body 8 is equipped with a fuel heating source 9 made of an electric heater on its peripheral wall, has a liquid fuel inlet 10 in its lower part, and has a fuel heating source 9 in its upper part.
The fuel gasified by Bunsen burner 4
The structure includes a gasified fuel outlet 11 for supplying gasified fuel to the gasified fuel. Here, the electric heater forming the heating source 9 is heated by an AC 100V power source. And gasified fuel outlet 11
is equipped with a gas supply amount adjusting tool 12. The gas supply amount adjusting device 12 is formed by an electromagnetic valve having a needle valve as a valve for adjusting the degree of opening of the gasified fuel outlet 11, and the amount of movement of the needle valve by the operation of the electromagnetic valve is However, gasified fuel outlet 1
By adjusting the opening degree of No. 1, the amount of gas supplied can be adjusted. Further, an electromagnetic pump 14 of the fuel supply section 3 is connected to the liquid fuel inlet 10 via a fuel supply pipe 13.

The fuel supply section 3 includes a liquid fuel tank 15, an electromagnetic pump 16 that supplies a fixed amount of fuel in the liquid fuel tank 15 to the gasification section 2, and a control section 17 for controlling the electromagnetic pump 16 and the gas supply amount regulator 12. It is composed of Here, petroleum (kerosene) is usually used as the liquid fuel. The electromagnetic pump 16 is of a vertical type and is arranged so as to be able to supply a fixed amount of liquid fuel intermittently, and to be able to supply the liquid fuel to the liquid fuel inlet 10 of the gasification section 2 via the fuel supply pipe 14. I have to. The control unit 17 is a control unit for adjusting the burner calorific value, and is an operation unit for adjusting the operation of the electromagnetic pump 16 and the gas supply amount regulator 12. The adjustment is usually made in four stages: strong, medium, weak, and fine.

The furnace of this embodiment based on the above configuration is
The fuel heating source 9 such as an electromagnetic heater is operated, and the control section 17 is operated to operate the electromagnetic pump 16 to supply a desired amount of liquid fuel from the liquid fuel tank 15 to the gasification section 2 . The liquid fuel flowing into the vertically hollow heating element 8 forming the gasification section 2 from the liquid fuel inlet 10 is gasified by the heating source 9 disposed on the peripheral wall of the vertically hollow heating element 8. At the same time, the gas rises and is heated and expanded in the upper region. Then, the opening degree of the gasified fuel outlet 11 is adjusted by the gas supply amount adjusting tool 12 which is linked to the operation of the control unit 17, and gas according to the opening degree is passed through the gasified fuel outlet 11 to the Bunsen. It is ejected and supplied to the burner 4 and ignited via the igniter 5.

Here, the calorific value is adjusted by controlling the supply of liquid fuel by operating the control unit 17 and by controlling the degree of opening of the gasified fuel outlet 11 by the gas supply amount regulator 12. Let's do it. By the way, the control section 17 that controls the liquid fuel supply and the gas supply amount regulator is not integrated with the gasification section and the gas burner section, but is separated and installed outside the furnace, and the above controls can be operated remotely. It may also be done by.

Note that the present invention is not limited to the embodiments described above, and includes modifications that can be made without changing the gist of the present invention. Incidentally, in the above-mentioned embodiment, the furnace was explained using the configuration of a normal furnace. It is obvious that it may also be configured such that it is installed. In this case, the control unit, electromagnetic pump,
In particular, it is preferable that the control section is separated, and only the gas burner section and the gasification section constituting the furnace are disposed between the inner pot bottom and the outer cover to heat the inner pot bottom. By doing this, when the rotary pot is tilted, the liquid inside the pot will fall out.
In addition to preventing the electrical system that forms the control section from getting wet, unlike a regular gas-based furnace, it takes time to ignite, so if it is separated and controlled from the outside, its operability will be improved. It will show advantages.

Further, if necessary, the longitudinally hollow heating body may be provided with a tar removal mechanism in order to remove tar generated during gasification. In this case, any structure may be used as long as a tar reservoir such as an opening/closing lid is provided at the bottom of the elongated hollow heating body and the tar from the reservoir can be discharged.

[Effect of idea]

This has the effect of promoting the gasification of the fuel, as well as quickly supplying the gasified fuel to the burner, thereby shortening the ignition time.

Therefore, according to the present invention, it is possible to provide a furnace that has a simple configuration and can reduce fuel consumption while maintaining an ignition speed comparable to that of a furnace that uses ordinary gas as fuel. have an effect.
