[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combustor in which kerosene and other liquid fuels are vaporized and burned.

[0002]

2. Description of the Related Art Conventionally, a bottomed cylindrical combustion cylinder comprising an inner cylinder and an outer cylinder is inserted through the inner cylinder and the outer cylinder and tightened with a screw, so that an ignition plug is connected to the inner cylinder and the outer cylinder. For example, Japanese Unexamined Utility Model Publication No. 60-32624 discloses a device for fixing electrical components such as
Tei Ru.

[0003]

However, the inner cylinder and the outer cylinder, particularly the inner cylinder, constituting the combustion cylinder have a large temperature difference between the time of combustion and the time of stoppage of combustion, and the expansion and contraction are repeated accordingly. For this reason, when the inner cylinder and the outer cylinder are heated, an electric component such as a spark plug is fixed to the inner cylinder and the outer cylinder by penetrating the inner cylinder and the outer cylinder and tightening with a screw. The electrical components such as the spark plug may be loosened and the electrical components may rotate.For example, when the electrical components are ignition electrodes, the ignition electrodes may be too far or too close to the ground electrode, and may be too close to the ground electrode. In the case where the electrical component is a flame rod for monitoring a flame, the flame rod comes into contact with the ground side, making it impossible to detect a flame current. It is an object of the present invention to obtain a liquid combustor in which such a problem is solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in the drawings.
In the drawing, 1 is a bottomed cylindrical combustion cylinder comprising an inner cylinder 1a and an outer cylinder 1b, 2 is a combustion chamber formed in the combustion cylinder, 3 is a hat-shaped vaporization cylinder provided in the combustion chamber 2, Reference numeral 4 denotes an air cylinder facing the vaporizing cylinder 3 and 5 denotes an air supply chamber connected to the air cylinder 4. The vaporizing cylinder 3 has a fuel scatterer 6 on the lower surface and fuel scatters around the lower part. A gap 7 is provided, which is inserted through an opening provided at the center bottom of the inner cylinder 1a and the outer cylinder 1b, and is supported by the upper end of a rotating shaft 8 facing the combustion chamber 2 so that the inside of the combustion chamber 2 It is provided so as to rotate with. Reference numeral 9 denotes an ignition electrode as an electrical component that penetrates through the inner cylinder 1a and the outer cylinder 1b and faces the combustion chamber 2. Reference numeral 10 denotes a ground electrode provided in the inner cylinder 1a facing the ignition electrode 9. Is shown. When the fuel is supplied to the fuel scatterer 6 while rotating the vaporizing cylinder 3 by the motor 11 connected to the rotating shaft 8, the fuel diffuses along the fuel scatterer 6 and the fuel is diffused along the fuel scatterer 6. After flowing down along the inner peripheral surface, the fuel is scattered into the combustion chamber 2 from the fuel scatter gap 7. If this is ignited by a spark formed between the ignition electrode 9 and the ground electrode 10, the fuel will live-combust in the combustion chamber 2. When the vaporization cylinder 3 is heated by the combustion, the fuel flowing down along the inner peripheral surface of the vaporization cylinder 3 evaporates and is mixed with the air supplied through the air cylinder 4, and is mixed with the inner cylinder 1 a and the outer cylinder. The process shifts to a so-called vaporization combustion in which the fuel is burned while being ejected from a flame hole 13 provided in the inner cylinder 1a through a passage 12 formed between the cylinder 1b. Until now, there is no particular difference from those conventionally known.

[0007] In the present invention Hakakaru stuff, which was provided with a round Ri stop means 14 on the fastening portion of the ignition electrode 9 as electrical instrumentation components, is that shown in FIG. 1 to FIG. 4, the ignition electrode 9 and
An integral screw cylinder 17 is provided on the bottom plate of the inner cylinder 1a and the outer cylinder 1b .
A nut 18 provided on the screw cylinder 17 is provided through the through hole.
In, shows an embodiment in which so as to tighten fixed to the bottom plate of the inner cylinder 1a and the outer tube 1b, in this embodiment, prior to該螺tube 17
As serial times Ri stop means 14, holes 14 for inserting the該螺tube 17
e and an abutting portion 14c abutting on the inner peripheral surface of the inner cylinder 1a, and
The stepped portion 14d with which the outer surface of the square flange 17a is in contact
The washer 14 is provided with the square flange 17a and the bottom of the inner cylinder 1a.
Even if the tightening is loosened ,
The washer 14 and the ignition electrode 9 integrated therewith are prevented from rotating by the washer 14 .

[0008] embodiment shown in FIG. 5 and FIG. 6 is provided an ignition electrode 9 integral with the threaded tube 17 by penetrating the bottom plate of the inner cylinder 1a and the outer tube 1b, as the detent means 14, Inner cylinder
Protrusions 20, 20 were provided on the inner surface of 1a. That is, the inner cylinder 1a
Hexagonal shape of the upper end of the screw cylinder 17 by embossing on the bottom plate of
The two convex portions 2 are provided at locations where the flanges 17a come into contact with the outer periphery.
0, and the upper end flank of the screw tube 17 is provided on the convex portions 20 and 20.
By contacting the outer periphery of the die 17a, the ignition electrode 9 is connected to the inner and outer cylinders.
When the cylinder 1a and the cylinder 1b are heated, they do not rotate.

[0009] As the electrical instrumentation components not limited to the ignition electrode 9, even without Mosu it may be a flame rod 19 shown in Figure 3, limited to be above embodiments Matakai Ri stop means 14 It is not something that can be done.

[0010] Further, a liquid combustor for vaporizing and burning kerosene has been described.
Needless to say, the present invention can also be applied to a so-called gun pot type liquid combustor known in Japanese Utility Model Laid-Open Publication No. 50-27432 in which fuel is injected from a nozzle and burned.

[0011]

The liquid combustor according to the first aspect having the above configuration has the following effects. The inner cylinder and the outer cylinder expand and contract due to the temperature difference between the time of combustion and the time when combustion stops, and even if the tightening by the nut of the screw cylinder is loosened due to this effect, the angle of the cylinder integrated with the electrical components When the outer surface of the mold flange hits the step of the washer, the electrical component can be prevented from rotating, and a defect due to the rotation of the electrical component, for example, when the electrical component is an ignition electrode, the ignition electrode is connected to the ground electrode. If it is too far or too close to form a spark with the ground electrode, and if the electrical component is a flame rod that monitors the flame, the flame rod contacts the ground side and detection of flame current is not possible. Inconveniences such as the possibility can be solved. The liquid combustor according to claim 2 having the above configuration has the following effects. Due to the temperature difference between the time of combustion and the time of combustion stop, the inner cylinder and the outer cylinder expand and contract, and due to this effect, the tightening of the screw cylinder nut may loosen,
The outer surface of the rectangular flange of the cylindrical body integrated with the electrical component hits the convex portion, which prevents rotation of the electrical component and causes a problem due to rotation of the electrical component, for example, the electrical component is an ignition electrode. When the ignition electrode is too far or too close to the ground electrode, a spark cannot be formed between the ignition electrode and the ground electrode,
When the electric component is a flame rod for monitoring a flame,
Problems such as the flame rod being in contact with the ground side to make it impossible to detect a flame current can be solved.
