The present invention relates to the combustion of the fuel of the petroleum heater by injection vaporization, and more particularly to the combustion apparatus of the petroleum heater improved by efficient diffusion of fuel and a stable combustion state.

Conventional petroleum heaters inject liquid petroleum from the nozzle to vaporize the surface heat of the carburetor, where the injected fuel partially comes into contact with the surface of the carburetor, causing poor combustion conditions such as sulfur salts and sparks. Due to this, there is a problem in that foreign substances such as tar are added to the lower end of the injection. Also, the vaporized gas is vortexed due to the mixing of air for combustion. There were several problems.

In order to solve the above problems, the present invention provides a barrier film inside the vaporizer and enables efficient diffusion through double diffusion through the nozzle A and the diffusion nozzle B, and also forms a vaporization gas induction part in the burner head. And the inner burner head is built so that a stable combustion can be made, according to the embodiment of the accompanying drawings illustrating the configuration and effect in detail as follows.

According to the present invention, the carburetor with the heater 5 installed therein and the temperature sensor 6 is inserted into and fixed to the carburetor cover 7, and the air outlet groove 11a is inserted into the delivery pipe 8 and a known nozzle from one side. The nozzle body 13 is formed between the nozzle body 11 and the nozzle bracket 12 on which the carburetor cover 11 is formed, and is fixed to a predetermined position on the outer circumferential surface of the carburetor 4 through the hole of the carburetor cover 7. Mounting and fixing the burner head 15 in which the packing 14 and the flame guide net 16 and 16 'are welded to the upper surface of the vaporizer 4, and into the burner head 15, the rectifying pipe A 18, Inner net 19, rectifying plate B (20) and burner caps A, B, C (21, 22, 23) are sequentially installed through the burner fixture 24, the nozzle body 11 to one side A nozzle A (9) and a diffusion nozzle B (10) having a diffusion protrusion (10a) are inserted into the discharge pipe (8) on the side of the discharge pipe (8). A barrier film 4a is provided, and an inner burner head 17 having a plurality of holes 17a perforated only in one direction is formed inside the tubular induction part 15a at the bottom of the burner head 15. Reference numeral 1 denotes an electronic pump, 2 a fuel tank, 3 a combustion air motor, and 25 a holder for fixing the delivery pipe 8 to the nozzle body 11.

As shown in FIG. 5 and FIG. 2 of the present invention configured as described above, when the power is applied to heat the heater 5 built in the vaporizer 4, the temperature sensor 6 mounted on the vaporizer 4 is applied thereto. As the sensing signal is transmitted to the microcomputer as a control means, the microcomputer sends a control signal according to the sensing signal to operate the combustion air motor 3 to supply the air necessary for combustion, and also to provide a vaporizer ( When 4) reaches the set temperature, the electronic pump 1 is operated by the control signal of the microcomputer, and the fuel is supplied from the fuel tank 2 to the delivery pipe 8 through the supply line. 8) The fuel supplied to the nozzle 1 is primarily injected from the nozzle A (9) having a small diameter inserted into the nozzle body 11, and the fuel injected first passes through the diffusion nozzle B (10) and the diffusion protrusion (10a). Is diffused and sprayed into the vaporizer (4). External air introduced from the air motor 3 for the air is supplied into the vaporizer 4 through the air inlet hole 11a formed in the nozzle body 11 and mixed with the fuel that is diffused and sprayed as described above. The vaporizer 4 has a large contact surface inside the vaporizer 4 heated by the vaporizer, and is discharged upward through the tubular guide portion 15a of the burner head 15 installed on the upper surface of the vaporizer 4 as shown in FIG. In the flame guide network 16, 16 'which is inserted into the outside of the burner head 15 through a plurality of holes 17a formed at one side of the rectifying plates A, B 18, 20 and the inner burner head 17. Finally it will burn.

Here, since the blocking film 4a, which is a vortex preventing means, is formed inside the vaporizer 4, fuel vaporized by the above-described means inside the vaporizer 4 during actual use may cause the induction part 15a of the burner head 15 to be removed. Vortex phenomena due to the mixing of combustion air before it is discharged prevents the release of fuel that is not remixed or completely vaporized with liquid fuel.

As described above, the feed fuel passes through the nozzle A (9) and the diffusion nozzle B (10), is dispersed and sprayed, and mixed with the air supplied, thereby having a wide contact surface to the heated vaporizer 4 as a vaporized gas It is converted to prevent sulfur salts and sparks, and remixing of vaporized gas and injected fuel is prevented by the blocking film 4a, and thus it is possible to achieve complete combustion by preventing vortex. Will have.
