Reference numeral 31 denotes an oil pipe that communicates the leveler 32 and the sub-tank 27.

33 is a substrate.

A layer 34 made of foam material is provided on the entire inner surface of the damper 12.

Next, the operation will be explained.

First, the electric heater 2 is energized and the vaporizer 1 is heated to 200 to 250 volts.
Preheat to ℃.

When the motor 20 is energized after preheating is completed, the rotating plate 22, fan impeller 23, and pump impeller 2 fixed on the same axis
4 rotates.

As a result, a fixed amount of fuel in the sub-tank 27 is continuously supplied to the rotating plate 22 by the pump impeller 24, and the fuel is scattered around the entire outer circumference of the rotating plate 22 by centrifugal force and is atomized.

The atomized fuel passes through the opening 13 of the damper 12, hits the inner wall of the vaporizer 1, and is gasified.

The fuel that hits areas other than the opening 13 of the damper 12 falls down the inner wall of the damper 12 and returns to the sub-tank 27 from the bottom of the atomization container 10 through the drain pipe 30. On the other hand, the air sucked by the fan impeller 23 flows through the damper 12. The gas enters the vaporizer 1 through the opening 13 of the burner head 6, mixes with the vaporized gas, and is ejected outward from the flame hole 7 of the burner head 6, forming a flame 8 and combusting.

Also, by rotating the damper 12, the opening 13
The amount of atomized fuel that enters the vaporizer 1 changes, and at the same time, the amount of air required for combustion also increases or decreases.

In this way, by rotating the damper 12, the combustion amount can be adjusted while always keeping the air-fuel ratio constant.

In the combustion apparatus of this embodiment, for example, the angle of the maximum opening 13 of the damper 12 is set to 45 degrees, and the rotating plate 22 is moved by the pump.
Add 20,000Kcal/h (approx. 2.57/h) of white kerosene on top.
h), the fuel entering the vaporizer 1 is 200
00X45'/360° and 2500Kcal/h is obtained.

Also, depending on the position relative to the atomization container 10, the effective opening angle of the opening 13 of the damper 12 is gradually reduced to 9°, which is 50°.
0 Kcal/h will be obtained.

In this way, by setting and rotating the opening angle of the damper 12, the combustion amount can be freely set and adjusted over a wide range.

Extinguishing the fire can be easily done by turning off the power to the motor 20 and stopping it.

Further, the opening 13 of the damper 12 may be completely closed.

In this way, in this embodiment, the combustion amount can be freely set and adjusted over a wide range by setting and rotating the opening angle of the damper 12.

Extinguishing the fire can be easily done by turning off the power to the motor 20 and stopping it.

Further, the opening 13 of the damper 12 may be completely closed.

Here, in this embodiment, the fuel that collides with a portion other than the opening 13 of the damper 12 is removed from the layer 3 provided on the inner wall of the damper 12.
4, and without being dispersed, it descends inside and on the surface of the layer 34, passes through the drain pipe 30, and returns to the sub-tank 27.

Note that the foam layer 34 may be provided so as to surround the entire circumference of the rotary plate 22 as in this embodiment, but it may also be provided partially.

As described above, the present invention has the following effects.

In other words, among the fuel particles scattered from the rotating body, those that collide with the inner wall of the damper atomizer are absorbed by the foam layer and flow to the drain pipe without scattering, so that the fuel particles return to the rotating body. As a result, it is possible to prevent the scattering pattern of fuel particles from the rotating body from being disturbed and the concentration of the fuel to be prevented, so that the amount of fuel supplied is stabilized without fluctuation.

This eliminates lifting, flashback, etc. caused by vaporization delays and fluctuations in the amount of vaporization, making it possible to stabilize combustion and expand the variable range of combustion amount, making it possible to maintain a low combustion amount without producing soot or odor. , comfort and energy savings can be achieved.
