Description

[Detailed Description of the Invention] The present invention relates to a gasification oil combustion device that heats and vaporizes kerosene and gasifies and burns it in a combustion cylinder.

Conventionally, this type of gasification type oil combustion equipment is shown in Figure 2.
Inside the burner body, which has a heater tie embedded in the side wall to form a vaporizing chamber opening, is installed an atomizer consisting of a rotary cone, a diffuser plate, and a stirring plate, and which is rotationally driven by a motor shaft. The fuel supplied from the liquid fuel supply pipe is scattered on the side wall of the vaporization chamber mouth by the atomizer, and this scattered fuel is vaporized by the heat of the heating heater and is ejected from the flame roll of the burner head as a gas mixture. It is configured so that when the combustion occurs, green flame burns inside the combustion tube.
In this conventional example, the combustion tube O is connected to the flange portion of the burner body through a heat insulating material 7 so that the heat of the heater tie is not conducted to the combustion tube O.

Therefore, the self-heating effect of the burner cannot be expected to be very high, and the heating tie must be continuously energized for a long time in order to maintain the burner body at a temperature at which kerosene can be vaporized.

The present invention was developed in view of the above points, and is an improvement that allows the heat of the combustion tube to be directly conducted to the burna body.

The present invention will be explained below based on the embodiment shown in FIG.

In the figure, reference numeral 1 denotes an air-air case in which a motor 2 is installed, and intake fans 3, 3, which are surrounded by the motor 2, are installed in the lower part of the case.
It communicates with the outside through an outside air intake port 4 formed in the bottom wall.

Reference numeral 5 denotes a burner connected to the air housing 1 through a heat insulating plate 6, and flame ports 9, 9, . We have established
The burner body 8 has flame ports 9, 9 together with the burner head 7.
The body top 8a forming the body top 8a is molded from a material with a high melting point such as cast iron, and the body top 8a
The main body 8 is removably screwed into the upper end opening.
b is die-cast molded from a material such as an aluminum alloy with high thermal conductivity, and the main body 8b is equipped with a heater 10.
is buried inside the main body 8b of the vaporization chamber A,! At the same time, the vaporizing chamber A and the inside of the air housing 1 are configured to communicate through an air supply port 11 formed in the bottom wall.

Reference numeral 12 denotes a rotary atomizer mounted on the shaft 2a of the motor 2 inserted into the vaporization chamber A from the air supply port 11.
a, a diffusion plate 12b, and a stirring plate 12C.

Reference numeral 13 denotes a liquid fuel supply pipe whose tip opening faces closely to the cone 12a of the atomizer 12, and communicates with an oil amount regulator etc. via a solenoid valve 14.

Reference numeral 16 denotes a hollow cylindrical steel combustion tube connected and integrated with the burner body 8. The burner body 8 is inserted through the connection side end of the combustion tube 16, and the body main body 8b of the burner body 8 is inserted. A cylindrical abutting part is formed which makes surface contact with the outer surface of the peripheral wall, and the lower end of the abutting part 16a is attached to a fixing flange 17 formed on the body main body 8b via a heat insulating material 18. The flange portion 16C is bent outward.

Further, reference numeral 19 denotes an ignition plug facing near the flame port 9 of the burner 5, and this ignition plug 19 penetrates through the bottom wall of the combustion cylinder 16 and is fixed.

Next, to explain the operation, after the main body 8b of the burner body 8 is heated by energizing the heater 10 and the peripheral wall of the vaporization chamber A reaches a temperature at which kerosene can be vaporized, the motor 2 is started and the atomizer is activated. 12 is rotated, and fuel is supplied to the atomizer 12 from the liquid fuel supply pipe 13.

The fuel atomized by the atomizer 12 is vaporized in the vaporization chamber A, and this vaporized gas is mixed with the accelerated air from the vaporization case 1 to form a gas mixture, and the flame ports 9, 9... - It is ejected and ignited and burned by the spark plug 19.

The calorific value of this burner 5 is approximately 3600 Kcal.
/h, the lower part of the combustion tube 16 is exposed to the combustion flame for about 4 hours.
The body is heated by combustion to about 00 to 500°C, and the combustion heat is conducted to the main body 8b through the contact portion 16a, so that the main body 8b can be heated.

In this way, when the burner 5 becomes able to maintain the temperature at which kerosene can be vaporized by self-heating, the power supply to the heater 10 is stopped.

Next, the assembly method of the present invention will be briefly explained.

First, after completing the assembly of the air housing 1, the body main body 8b is screwed to the upper part of the air air housing 1, and then the cone 12a,
The diffusion plate 12b and stirring plate 12C are sequentially mounted on shafts and fixed with nuts.

Furthermore, a heat insulating material 1 is attached to the fixing flange 17 of the main body 8b.
8, the combustion tube 16 is fitted into the main body 8b, and the fixing flange 17 and the mounting flange 16 of the combustion tube 16 are attached.
C with bolts and nuts, and the main body 8b
After the body top 8a is screwed onto the upper part of the body top 8a, the burner head 7 may be placed in the upper opening of the body top 8a.

In this way, the present invention connects the combustion tube by bringing the abutting part of the combustion tube into contact with the outer surface of the peripheral wall of the burner body, whose interior is used as a vaporization chamber, so that the combustion heat of the burner is reliably transferred to the burner body. Therefore, it is possible to shorten the energization time of the heater and save electricity, and when this combustion device is used in a hot air heater, the heat stored in the burner is conducted back to the combustion tube when combustion is stopped. Therefore, it can be effectively used as hot air.

Further, the burner body is formed separately into a body lug and a body main body having a heater so that they can be attached to and detached from each other, and the body main body is made of a material with high thermal conductivity, and the body lub is separated from the body main body. Since it is made of a material with a high melting point, the heat generated by the heater can be effectively used to vaporize the liquid fuel, and it is also possible to prevent deterioration of the flame port due to combustion heat.
