In addition, the upper end portion of the inner burner body 7 is formed with a protrusion 7b protruding upward, and the first to third rectifying members 9 and 10 inside and outside the protrusion 7b. The inner and outer cutouts are formed so that 11, the hood burner 13, and the burner head 14 can be mounted, respectively.

The first and third rectifying members 9 and 11 are each provided with a plurality of rectifying holes 9a and 11a to rectify and pass the mixed gas formed at a high temperature and high pressure in the vaporization chamber. The second rectifying member 10 is formed with an induction hole 10a for guiding the mixed gas upward so as to increase the outflow pressure of the mixed gas.

In addition, a rectifying network 16 is attached to the periphery of the third rectifying member 11 to rectify the mixed gas into fine particles, and the outflow of the mixed gas is easily above the rectifying network 16. The heat shield plate 15 is formed with a bent portion at the center to be guided. In addition, the burner head 14 has a press-formed integral type, and has a salt hole 14a formed in the side wall portion, and reduces noise generated during combustion inside and outside the side wall portion of the burner head 14, The inner metal mesh 17 and the outer metal mesh 18 having fine meshes are attached to prevent the outflow of unrectified mixed gaseous gas, respectively.

On the other hand, the outer circumferential surface of the venturi tube 20 is hermetically contacted with a through hole (not shown) formed in the sidewalls of the outer burner body 1 and the inner burner body 7, and formed on the inner burner body 7. The through-hole is screwed with the threaded portion formed on the outer peripheral surface of the distal end of the venturi tube 20 and is hermetically coupled.

On the other hand, the nozzle body 22 is a combustion air induction member 26 to guide the combustion air generated by the blower fan 23 interlocked by the driving of the blower motor 25 to the inner burner body (7). Is connected to one side, and the other side of the nozzle body 22 is formed with a hollow screw portion (22a).

The thermistor 34 is formed on the side wall of the outer burner body 1 facing the tip of the nozzle 31 by the fixing means 35 so as to sense the temperature of the side wall portion 7c of the inner burner body 7. ) Is fixed.

When power is applied to operate a conventional petroleum combustion device configured as described above, and an operation unit (not shown) is operated, the preheating heater 6, which is the first heat source, generates heat to generate the side wall portion of the inner burner body 7. The inner burner body 7 is preheated so that the petroleum fuel arriving at 7c) may be vaporized, and the temperature of the preheated inner burner body 7 is sensed by the thermistor 34 and transferred to a microcomputer (not shown). When the temperature of the inner burner main body 7 transmitted to the microcomputer is higher than a predetermined temperature, the blower motor 25 and the electronic pump 29 are operated in the microcomputer.

At this time, the combustion air generated by the driving of the blower motor (5) equipped with the blower fan (23) is the inner burner from the venturi tube (20) via the combustion air guide member (26) and the nozzle body (22). The petroleum fuel discharged into the main body 7 and pumped in the oil tank not shown by the operation of the electronic pump 29 at the same time passes through the nozzle pipe 30 and from the nozzle 31 to the inner burner main body 7. Is discharged to the side wall portion 7c.

In addition, the combustion air and the petroleum fuel in the inner burner body 7 collide with the preheated inner burner body 7 to form a high-temperature mixed gaseous gas while being vaporized, and are simultaneously raised to raise a plurality of rectifying members 9. 10a, 11, and salt holes 14a formed in the side walls of the burner head 14 in a state of being atomized while being easily passed through the storage nets 16 to the inner and outer metal nets 17 and 18. Out).

However, the burner vaporization apparatus of the petroleum combustion apparatus according to the prior art configured as described above, as shown in FIG. An angle formed by the ends of the 31 forms a substantially vertical bar. As the petroleum fuel concentrates and collides with a limited portion of the inner burner body 7, an instantaneous temperature drop of the inner burner body 7 occurs. It was. Therefore, the petroleum fuel that collides with the side wall 7c of the inner burner body 7 is not vaporized and flows to the bottom of the inner burner body 7 to be mixed with fine foreign substances sucked into the vaporization chamber to form tar. There was this. In addition, as the vaporized petroleum fuel and combustion air are combusted without being properly mixed, sulfur salts are generated, and there are problems such as odor due to incomplete combustion.

The present invention has been made to solve the above problems, an object of the present invention is to increase the vaporization efficiency of petroleum fuel, burner vaporization apparatus of petroleum combustion equipment that can be easily mixed with the vaporized petroleum fuel and combustion air To provide.

In order to achieve the above object, a burner vaporization apparatus of an petroleum combustion device according to the present invention includes an inner burner main body for vaporizing petroleum fuel, a nozzle for injecting petroleum fuel into the inner burner main body, and a combustion air to be sucked in. The blowing motor for operating the blowing fan and the combustion air sucked by the blowing fan linked to the blowing motor are mixed with the petroleum fuel injected by the nozzle to atomize the mixed gas vaporized by the inner burner body. In the petroleum combustion device having a plurality of rectifying members, the inner burner body having a cross section forming an involute curve so that the combustion air and the petroleum fuel is vortexed and easily mixed, and the side wall portion of the inner burner body and The end of the nozzle is provided with a nozzle disposed obliquely at a predetermined angle so that petroleum fuel can be easily vaporized It shall be.
