Description

[Detailed description of the invention] This invention atomizes liquid fuel such as white kerosene using the centrifugal force of a rotating body, and vaporizes the atomized fuel by colliding with a high-temperature section provided in a vaporization chamber. An object of the present invention is to provide a combustion device that performs post-combustion, which can reliably vary the amount of combustion to a minute amount and can stably perform combustion to achieve a desired load.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes an atomizer that atomizes liquid fuel by the centrifugal force of a rotary plate 2. It has a rotatably supported damper 5, and also has a refueling vibro for dripping liquid fuel on the upper surface of the rotary plate 2.

7 is a lid mounted on the top surface of the atomizing container 3 via a packing 8, and 9 is a lever for rotating the rotary plate 2.

Reference numeral 10 denotes a vaporizer installed at the outlet of the atomizer 1 via a heat insulating material 11. It has a burner head 15 and a flame port 16 above it.

Reference numeral 17 indicates a combustion flame rising from the flame port 16.

18 is a pump impeller for feeding oil to the oil supply vibro;
It is driven by a motor 19.

20 is a leveler, 21 is an oil pipe, 22 is a sub tank, 23 is a pump case, and 24 is a drain pipe.

A fan impeller 25 is driven by the motor 19, which sucks air through a suction port 26 and supplies combustion air into the atomizer 1.

27 is a fan case. Further, the rotating plate 2 is also driven by the motor 19.

The feature of the present invention lies in the shape of the damper 5. As shown in FIG. The reason is that the inclined opening 52 is formed.

The atomized liquid fuel is supplied from the atomizer 1 to the vaporizer 10 through this opening 52.

Next, the operation will be explained.

First, the electric heating motor 19 is energized and the vaporizer 1 is heated to 200 to 250 liters.
Preheat to 0°C.

When the motor 19 is energized after preheating is completed, the rotating plate 2, fan impeller 25, and pump impeller 18 fixed on the same axis
rotates.

As a result, a fixed amount of fuel in the sub-tank 22 is continuously supplied to the rotary plate 2 by the pump impeller 18, and the fuel is scattered around the entire outer circumference of the rotary plate 2 by centrifugal force and is atomized.

The atomized fuel passes through the opening 52 of the damper 5, hits the inner wall of the vaporizer 10, and is gasified.

The fuel hitting areas other than the opening 52 of the damper 5 falls down the inner wall of the damper 5 and returns into the sub-tank 22 through the drain pipe 24 from the bottom of the atomization container 3.

On the other hand, the air sucked in by the fan impeller 25 enters the vaporizer 10 through the opening 52 of the damper 5, mixes with vaporized gas, and is ejected outward from the flame hole 16 of the burner head 15, forming a flame 17. and burn it.

Further, by rotating the damper 5, the size of the opening 52 changes, and the amount of atomized fuel entering the vaporizer 10 increases or decreases, and at the same time, the air required for combustion also increases or decreases.

In this way, by rotating the damper 5, the combustion amount can be adjusted while always keeping the air-fuel ratio constant.

In the combustion device of the present invention, for example, the opening 5 of the damper 5
The angle at which the opening area of 2 is maximum is 45°, and white kerosene is pumped onto the rotary plate 2 at a rate of 20,000 Kcal/
h (approx. 2.5//h), the fuel entering vaporizer No. 10 becomes 20000X45°/3600, and 2500 KCa J/h is obtained.

Also, depending on the position relative to the atomization container 3, the damper 5 opening 52
If the effective opening angle of the engine is gradually decreased, the amount of combustion will gradually decrease.

In this way, by setting and rotating the opening angle of the damper 5, the combustion amount can be freely set and adjusted over a wide range.

In this embodiment, since the damper 5 is provided with the inclined opening 52, the rotation range can be made larger than that of the conventional example shown in FIG.

That is, if the rectangular opening 52' and the inclined opening 52 have the same opening area as shown in FIG. The degree of decrease will be smaller when

Therefore, the combustion amount can be stably varied from the maximum combustion to the minimum combustion, and since the combustion amount does not change greatly near the minimum combustion part, this part can be easily varied.

Extinguishing the fire can be easily done by turning off the power to the motor 19 and stopping it.

Alternatively, the opening 52 of the damper 5 may be completely closed.

As described above, the present invention provides an inclined opening in the damper, and the atomized fuel that passes through this opening is vaporized and then combusted. Therefore, the combustion amount can be stably varied from maximum combustion to minimum combustion. In particular, variable control near minimum combustion can be performed stably and easily.
