Radiator for oil combustor {Radiator for oil burner}

TECHNICAL FIELD The present invention relates to the field of petroleum combustors, and more particularly, to a radiator for petroleum combustors that generates radiant heat while being glowing by vaporization of petroleum as a fuel.

In general, a petroleum combustor is one of heating devices that heat by using heat obtained by vaporizing and burning petroleum (kerosene), which is a fuel, a fuel supply device for supplying flammable fuel, and a fuel supplied from the fuel supply device. It is composed of a burner unit for vaporizing and burning the gas, and an air supply device for supplying external air to the combustion device to atomize the combustible fuel and supply air required for combustion.

This will be described in more detail with reference to FIG. 1 as follows.

Firstly, the fuel supply device includes a fuel tank 2 provided at a lower portion of the combustor body 1 to store fuel; And a fuel pump 3 for pumping fuel from the fuel tank and supplying the fuel to the combustion device.

The burner part, which is a core part of the combustor, has a cylindrical vaporizer 4 with a closed bottom surface; A preheat heater (5) embedded in the circumferential surface of the carburetor to preheat the carburetor (4) to vaporize the liquefied combustible fuel supplied from the fuel tank (2) at the beginning of ignition; A nozzle (6) formed integrally with one side of the vaporizer to introduce external combustion air by an air supply device (to be described later) to atomize the combustible fuel into small droplets and to supply air for combustion; A needle (7) installed on the inner central axis of the nozzle to inject and supply flammable fuel into the vaporizer; A port cap (or burner cap) 8 mounted on the upper opening of the vaporizer 4 and flowing into the vaporizer to eject the atomized gas to the top; A burner head 10 installed at an outer circumferential surface of the port cap and having a myriad of salt holes 9 formed therein; An ignition plug (11) installed at one side of the burner head to initially ignite the vaporized gas ejected through the salt hole (9); In order to always maintain a temperature range suitable for fuel to evaporate on the bottom surface of the vaporizer 4, the preheat heater 5 is turned on when the temperature is lower than the optimum temperature, and when the temperature is higher than the proper temperature, the preheat heater 5 is turned off. &Quot; a temperature sensor 12 for controlling the operation of the preheater so as to be able to; A port ring 13 installed at an outer circumferential surface of the burner head 10 to transfer heat generated during combustion to the vaporizer 4; A burner cover 14 which closes the upper surface of the carburetor so that the heat source is not lost due to the carburetor 4 being exposed to the outside of the port ring; It is provided on the burner head 10, and consists of a radiator 15 or the like in which combustion heat is secondaryly burned along the outer circumferential surface.

The air supply device is installed in the lower portion of the burner and the blowing fan 16 for sucking the outside air and blowing it to the burner; And a drive motor 17 for providing power to the blower fan.

Therefore, when power is applied to the combustor main body 1, a burner unit is operated to generate a preheating heater 5 embedded in the vaporizer 4, thereby preheating the vaporizer 4 to the extent that the liquid combustible fuel can be vaporized. .

Then, when the preheating of the vaporizer 4 is completed, the combustion air is supplied to the inside of the vaporizer 4 through the nozzle 6 by the combustion air supply device and at the same time the fuel pump 3 is driven by driving the fuel supply device. The liquid combustible fuel therein is injected into the vaporizer 4 through the needle 7 and is atomized into small droplets by the combustion air supplied through the nozzle holder 6a.

The atomized droplets thus spread and evaporate thinly while colliding with the inner wall surface of the vaporizer 4.

The vaporized gaseous gas is discharged upward along the flow path 8a of the port cap 8, at which time the vaporized gas is rectified by a pressure equalizing plate 18 installed at the lower end of the port cap 8. .

Further, the vaporized gas rectified by the pressure equalizing plate 18 is converted into a smooth, constant laminar flow of the high temperature and high pressure while passing through the port cap 8, and decelerated to the primary.

In this way, the first reduced vaporized gas collides with the upper surface of the conical burner head 10 to reduce the flow rate to the second, and is distributed to the upper portion of the burner head 10 in the conical shape and ejected to the outside through the salt hole 9. do.

In such a state, when the user presses an operation button (not shown) to generate sparks in the ignition plug 11 installed at one side of the burner head 10, the ignition is generated in the vaporized gas which is ejected, and thus the combustion of the vaporized gas is performed. Heating is performed by the heat of combustion.

Meanwhile, the conventional radiator 15 has a cylindrical shape as shown in FIG. 2, and numerous pores 15a are formed along the circumferential surface at regular intervals.

The radiator 15 is spaced apart from the top of the burner head 10 at a predetermined interval.

Therefore, when the coalesced flame generated from the burner part (exactly the burner head) flows into the lower part of the radiator 15, the primary activated air generated by the rotational power of the blower fan 16 is the nozzle holder 6a. ) → the carburetor (4) → while passing through the port cap (8) in order to activate the flame of the burner head (10).

In addition, the secondary flame activated in the burner head 10 is further activated by the surrounding air, that is, the secondary activation air, and flows into the radiator 15, and the flame is formed along the outer circumferential surface of the radiator. As it is scattered to the outside through) heating is achieved.

However, since the conventional radiator 15 as described above has a single cylindrical body, the secondary activated air flowing into the radiator is discharged directly through the pores 15a together with the flame without being able to stagnate, so that the entire radiator 15 is evenly distributed. The combustion heat is not transmitted and the phenomenon occurs that the part is biased.

Accordingly, only a portion of the radiator 15 where the secondary flames are scattered becomes a reddish red state, and there is a problem in that the visual emotional heating effect felt by the user is lowered.

In addition, due to the rapid release of the gas that has not been oxidized in the vaporizer 4, the oxidizing gas is not oxidized even in the radiator 15 and passes through the radiator 15 as it is. There was also a problem that has a harmful effect on the human body.

The present invention has been made to solve the conventional problems as described above, the purpose of which is to increase the combustion efficiency by delaying the discharge time so that the secondary flame introduced into the radiator can be stagnated for some time in the radiator before being scattered to the outside. It is to let.

Another object of the present invention is to increase the heating efficiency of the radiator by allowing the radiator to be totally glowing.

The present invention for this purpose is a plurality of pores are formed along the circumferential surface of the outer cylinder to be ventilated, the inner cylinder is spaced at a predetermined interval, the inner cylinder formed with a plurality of pores to be ventilated, between the inner cylinder and the outer cylinder A plurality of spaces provided in the longitudinal direction in the longitudinal direction to divide a plurality of spaces between the outer cylinder and the inner cylinder into a plurality, and a plurality of communication is formed in each of the interference members to communicate each space between the divided inner cylinder and the outer cylinder to each other A radiator for a petroleum combustor comprising a ball and a radiator holder to which upper ends of the inner and outer cylinders are respectively fixed are provided.

Hereinafter, the radiator of the present invention will be described in detail with reference to FIGS. 3 and 4 as follows.

First, a description of parts overlapping with the conventional configuration will be omitted as much as possible, and a description will be given focusing on the new configuration.

The double radiator 150, which is spaced apart at an appropriate distance above the burner head 10, consists of a cylindrical inner cylinder 151 and an outer cylinder 152, and a space between the inner cylinder 151 and the outer cylinder 152. In the portion, a plurality of interference members 153 in the shape of disks are provided at regular intervals and divided into a plurality of space portions.

The periphery of the inner cylinder 151 has a predetermined number of pores 151a of a predetermined size to be vented at appropriate intervals, and a predetermined size of pores 152a to be vented to the peripheral surface of the outer cylinder 152. A lot of holes are drilled at this proper interval.

On the other hand, the interference member 153 installed between the inner cylinder 151 and the outer cylinder 152 is opened so that the inner cylinder 151 penetrates in the center thereof, and a flange portion having a length corresponding to the interval between the inner and outer cylinders 153a is formed, and a communication hole 153b is perforated at regular intervals so that the flange portion communicates with each space portion between the inner and outer cylinders so that the air flowing into the lower portion can be vented to the upper portion.

”형을 이루고 있다.In addition, the interference member 153 has a joining piece 153c formed by bending the opening end downward in order to secure a bonding area to be easily bonded to the outer circumferential surface of the inner cylinder 151 by spot welding. The outer end of the interference member 153 is formed, the support piece 153d bent downwardly formed like the joining piece 153c for the smooth assembly of the outer cylinder 152, the overall cross-sectional shape is "

“I have a brother.

When assembling the double radiator 150 composed of such elements, each interference member 153 is inserted into the outer circumferential surface of the inner cylinder 151 by using a jig (not shown). After arranging at intervals, spot welding is fixed such that the inner surface of the joining pieces 153c of the interference members 153 is joined to the outer circumferential surface of the inner cylinder 151.

At this time, the interference member 153 is fixed to the interference member formed with the largest size of the pores 153b to be located in the lower portion of the inner cylinder 151, the pores 153b gradually smaller toward the upper portion of the inner cylinder 151 Arrange to lose.

The reason is that the secondary activated air flows into the lower portion of the radiator 150, but the size of the lower side pores serving as the inlet should be large, but a large amount of secondary activated air can be introduced therein.

Bonding the outer cylinder 152 to the outside of the interference member after joining each interference member 153 to the outer peripheral surface of the inner cylinder 151, the coupling of the double radiator 150 is completed, the inner cylinder 151 and the outer cylinder 152 is screwed to each of the radiator holder 154 located on the upper end of the combination of the double radiator 150 is completed.

Referring to the combustion process when the double radiator 150 is applied to the combustor body (1) as follows.

The coalescing flame rising from the burner head 10 flows into the inner cylinder 151, wherein the air is mostly introduced into the inner cylinder 151, and some of the communication holes are formed in the interference members 153. Guided upwards through 153b.

As such, the air guided between the inner and outer cylinders 151 and 152 has a large communication hole 153b of the interference member 153 located at the lower portion thereof, and gradually increases the communication hole 153b of the interference member 153 toward the upper portion thereof. Since the structure becomes smaller, a large amount of secondary activation air is introduced from the communication hole 153b of the lower interference member 153, and the inflow amount thereof is gradually decreased toward the upper interference member.

In the conventional radiator structure, the upper part becomes red glowing state, while the lower part is improved red heat problem, so that the amount of secondary activation air flows to the upper part less than the lower part to induce lower red heat. will be.

In addition, since the secondary activation air introduced into the double radiator 150 is radiated to the outside through the space portion of the inner cylinder 151 and the outer cylinder 152, it is possible to secure a time margin radiated to the outside compared to the conventional. do.

This can achieve complete combustion by delaying the time that the vaporized gas is oxidized in the radiator 150, thereby increasing the radiant heat.

The double radiator as described above has the advantage of increasing the radiant heat by giving a constant passion load to the secondary flame, as well as improving the emotional heating efficiency by allowing the radiator to be overall heated.
