A sufficient feed-back of heat to the gasified material 1 is provided under a heat conduction from the combustion plate 7, a gasification of fuel can be continued under a complete white-heat condition even if an energization of electric heater 2 is turned OFF after the cmbustion is started, resulting in saving an electric power.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention forcibly vaporizes liquid fuel with kerosene and burns it as a premixed gas with air, which is used as a heat source for home heaters, water heaters, etc. This relates to combustion equipment.

Conventional structure and its problems A conventional combustion apparatus of this type is constructed as shown in FIG. The premixed gas generated in the vaporized body 1 enters the flow regulating body 5, passes through the small hole 6, is ejected from the combustor 8 with the wire gauze throttle, is combusted, and is degassed through the holes in the gear and the knob 8.

The combustion body 7 is supported at both ends of the regulating fluid 50, and one end of the former regulating fluid 5 is connected to the vaporizing body 1. In this seed mixture combustion method, if the temperature of the combustion body 7 as well as the vaporization body 1 is not sufficiently raised at the time of ignition, the premixed gas will be cooled as it passes through the combustion body, and a smooth ignition will not be possible. ．． In the conventional example, during preheating, heat is transferred from the vaporized body 1 to the regulating fluid 5 (-1). etc.] It is necessary to use quality books, but the heat transfer is poor.

1. Even when the preheating of the vaporized body 1 is completed, the temperature of the regulating fluid 5 and the combustion body rises sufficiently, and when passing through these, the premixed gas is cooled down, causing a red-hot coil or an igniter using spark discharge. Even if it is used, ignition becomes extremely difficult.

-While the combustion body 7 is still separated from the vaporization body 1-, there is insufficient combustion heat f and direct heat conduction from the combustion body 7 to the vaporization body 1, and a smooth heat feed pack cannot be achieved.

,Purpose of the invention.

The present invention eliminates such conventional drawbacks, and aims to ensure the ignition timing when the preheating of the vaporized body 1 is completed, and to smoothly feedback the combustion heat to the vaporized body 1.・It is something.

Structure of the Invention In order to achieve this object, the present invention provides a groove in the vaporized body 1, into which one end of the combustion body is inserted, and also provides a small hole in a part of the vaporized body and positions the igniter near this groove. It is rich in things. □As a result, heat is directly applied to the combustion line during preheating of the vaporized material, and the temperature rises sufficiently, and the premixed gas passing through the small holes in the vaporized material is not rejected, which is a surefire point when using a boiler. Firepower goes to 1 line. In addition, combustion occurs even in the close vicinity of the vaporized body, and heat is conducted directly from the combustion plate, allowing for smooth heat feedback.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be explained using the drawing of FIG. It should be noted that the same parts in FIGS. 1 and 2 are designated by numbers.

In the figure, 1 is preheated by an electric heater 2 and a groove 3 is formed on the outer periphery with vaporized material.

11 1 11 4 is a partition plate, 5 is a flow regulator having a plurality of small holes 6, and a combustion body 7 made of a wire mesh, lath mesh, etc. is located outside of this. Reference numeral 8 forms a stepped portion 9 with a cap, to which the tip of an outer cylinder 10 made of a fluid regulator 5, a combustion body 7, glass, etc. is held and fixed concentrically.

11 is an air guide discharged into the inside of the vaporized body 1, and a hole 12.
13 are formed. Reference numeral 14 denotes a blower tube, which is connected to the leprosy fan 16 and has an outlet hole 16 for receiving exhaust gas. The first pipe is a pipe that guides the fuel supplied by a fuel supply means such as a pump to the vaporized body 1, and its dead end faces the hole 12 of the crystal guide 11. - Numeral 8 is a bolt that unitizes and fixes each structural element of the combustion device into a large unit, and each of the cap 8, fluid regulator 5, vaporizer 1, and blower tube 14 is connected and tightened. 19 is an igniter.

Next, the operation of this combustion device will be explained. First, when the electric heating temperature reaches ℃, the igniter, 9, blower i6 is energized to blow out combustion air from the hole 1'M of the air guide 11. □Next, feed the fuel from the tip of the eve 17o'□Then, the fuel becomes vaporized 1
□ This mixed gas of nucleated gas and air passes through the small holes 4 of the vaporized body 1 and is ejected from the combustion body 7, and □
The igniter 19 ignites and burns it.

Most of the four-way mixed gas enters the rectifier 5, passes through the small holes 6, and is ejected outward from the combustion body 7 to be combusted. The exhaust gas passes between the combustion body 7 and the outer cylinder 10 and is discharged from the outlet hole 15.
□ After combustion starts, a part of the exhaust gas comes into contact with the vaporized body 1 and is discharged □, and is heated by the conductive heat of the flow regulator 5 and combustion plate 7 to maintain a constant temperature □.Electric heater 2 and the igniter 19 to save power. Further, the combustion body T becomes red hot to a temperature of 700° to 50° and radiates radiant heat through the outer cylinder 1Q.

In this way, by connecting the combustion body A to the vaporization body 1, sufficiently preheating the combustion body 7, and allowing the mixed gas to pass through the small holes formed in the vaporization body 1 and ejecting it from the combustion body 7', The premixed gas contacts the igniter 19 in a high temperature state, and reliable ignition can be performed. In addition, the premixed gas passing through the small holes 4 of the vaporized body 1 reaches the igniter □19 earlier than the premixed gas passing through the small holes 6 of the regulating fluid 5, and the premixed gas passes through the small holes 6 of the regulating fluid 5.
A flame is formed in the vicinity of the combustion body 7, and the premixed gas jetted out is ignited with a delay, and the flame spreads over the entire surface of the combustion body 7, so that a very smooth start of combustion can be achieved.

In addition, by burning the combustion plate 7 near the groove 3 of the vaporized body 1 and by conducting heat from the combustion plate 7, a sufficient hot feed pack to the vaporized body 1 is achieved, and the combustion starts. Even if the power supply to the electric heating heater 2 is cut off, the fuel can continue to be vaporized in a completely incandescent state, resulting in significant power savings.

Effects of the Invention As described above, according to the present invention, the vaporized material passes through the small holes.
The premixed gas is not cooled, and the igniter can ignite the igniter more reliably, and combustion occurs even near the vaporized body, and heat is conducted directly from the combustion plate. This ensures sufficient heat feedback to the vaporized material, and even if the electric heater is turned off after combustion has started, the fuel can be vaporized in a completely incandescent state, resulting in power savings.
