In general, conventional combustion apparatuses using liquid fuels such as light oil, kerosene, bunker C oil, and refined waste oil have a simple structure such as petroleum burner, bunker burner or gasoline burner, which are forced to inject fuel by means of nozzles for combustion. By obtaining the heat source, the combustion apparatus using the nozzle injection method as described above is injected in the form of a drop of liquid fuel in the form of a small fuel that can not be burned, and thus incomplete combustion occurs.

In particular, high viscosity viscous oils such as bunker C oil and refined waste oil are difficult to spray themselves, resulting in massive combustion with incomplete combustion.

In the conventional combustion apparatus for burning liquid fuels, due to limitations of the combustion method, air is not sufficiently mixed with fuel, and combustion fuel particles are not uniformly distributed with air, and soot or toxic gas is generated. Most of the harmful gas is discharged to the outside without filtration, environmental hormones harmful to the human body such as dioxins and environmental pollution sources are adversely affected, and combustion efficiency is deteriorated depending on the type of liquid fuel.

In addition, the present invention comprises a two-stage combustion chamber having a narrow passage, but the oxygen can be supplied to the inside of the combustion chamber by an air supply pipe having a blower, by forming a plurality of vent holes in the air supply pipe, incomplete combustion harmful It is a very useful invention that can minimize the generation of complete combustion and pollutants by inducing the gas to be burned once again.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The combustion apparatus 100 of the present invention includes a housing 10 included in the combustion chambers 11 and 15, a soot exhaust pipe 20 installed on one side of the housing 10 so as to communicate with the combustion chamber, and a substrate 10a. A rotating body 30 coupled to the rotating body and having a top surface 30a for scattering liquid fuel, and a motor installed on one side of the housing 10 to provide rotational force to the rotating body 30. 70, an air supply pipe 55 extending through the combustion chambers 11 and 15 to supply oxygen into the combustion chambers 11 and 15, and one end thereof is connected to the fuel tank 60, and the other end thereof is A fuel supply pipe 65 for entering liquid fuel into the combustion chambers 11 and 15 and supplying liquid fuel to the center of the upper surface of the rotating body 30, and the liquid fuel injected and installed adjacent to the edge of the rotating body 30. It consists of an igniter 80 for igniting, and a control device (not shown) for controlling the operation of the motor 70, the igniter 80. It is broken.

The housing 10 is a cylinder supported by a leg, and includes combustion chambers 11 and 15, a second combustion chamber 15 formed above the first combustion chamber 11, and a first combustion chamber 11. It includes a narrow passage 13 formed between the second combustion chamber 15, and the soot discharge pipe 20 in communication with the second combustion chamber 15 and exposed to the outside.

The soot discharge pipe 20 may be formed to extend down to be immersed in the water tank 90, wherein the high heat is a blower 21 for blowing the soot into the water tank 90, the upper bent portion of the soot discharge pipe 20 Is installed in the but has a structure in which the blow pipe (21a) for blowing the soot down inserted into the soot discharge pipe (20). Thus the soot entering the water tank 90 is passed through the water filled in the water tank 90 and in this process the soot is dissolved or washed in water and the smoke 91 is discharged to the atmosphere.

In this case, the reason why the narrow passage 13 is formed between the first combustion chamber 11 and the second combustion chamber 15 is that the fuel that is not completely burned in the first combustion chamber 11 is the first combustion chamber 11 and the first combustion chamber 11. It is a structure for completely burning by the Venturi effect while passing through the narrow passage 13 having a diameter considerably narrower than the diameter of the combustion chamber 15. At this time, the internal volume of the second combustion chamber 15 is preferably smaller than the volume of the first combustion chamber (11).

The air supply device is a device for supplying the external air required for combustion, one end is exposed to the outside of the housing 10 and the other end penetrates the second combustion chamber 15 in the longitudinal direction, to the bottom of the second combustion chamber 15 As an apparatus for extending and inducing external air, the apparatus includes an air supply pipe 55 capable of supplying air (oxygen) around the rotor 30. At this time, one end of the air supply pipe 55, that is, the air inlet to form a blower 50 that can supply a large amount of high-pressure air to allow more oxygen to be introduced to facilitate the combustion.

At this time, the air supply pipe 55 located inside the housing 10 is formed with a ventilation hole 56 along the circumference, so that four ventilation holes perforated in all directions at a 90-degree angle are formed at regular intervals from the top to the bottom. , It is preferable to be formed to be twisted in a right angle direction, 45 degrees direction once.

This allows the air in the combustion chambers 11 and 15 to flow into the plurality of vent holes 56 to induce a more active flow of air, while the incompletely burned fuel and gas descends once again while the outside air is introduced. To induce combustion.

The fuel supply device includes a fuel tank 60 in which liquid fuel such as gasoline, diesel oil, kerosene, bunker C oil, and refined waste oil is stored, one end of which extends from the fuel tank 60 and the other end of the combustion apparatus will be described later. It is formed between the fuel supply pipe 65 and the fuel tank 60 and the fuel supply pipe 65 introduced into the first combustion chamber 11 so that the liquid fuel is supplied to the entire upper portion 30, and installed according to the type of liquid fuel. It includes a preheater 62 and a fuel pump (not shown) to be operable.

The preheater 62 serves to induce complete combustion of the fuel by melting the highly viscous fuel such as bunker C oil to facilitate flow, or preheating the liquid fuel in advance.

The combustion device comprises a rotating body (30) rotatably supported together with the shaft (31) by a bearing (33) on the lower surface of the first combustion chamber (11). At this time, the upper surface of the rotating body 30 is formed to be concave to be inclined upward, the cross section is preferably configured to have a dish shape.

At this time, the fixed body 40 to prevent the fuel falling on the rotor 30 to splash in a random direction and to allow the fuel to be scattered in a fine constant direction with a constant pressure, a certain size, a certain amount, It is preferably formed on the top of the rotating body (30).

At this time, the fixing body 40 has an inverted dish shape and is disposed coaxially with the rotating body 30 to cover the upper portion of the rotating body 30. The center of the fixed body 40 is disposed downward in the state where the fuel supply pipe 65 penetrates and is configured to face the center of the rotating body 30.

At this time, the edges of the fixed body 40 and the rotating body 30 should maintain a gap spaced apart from each other, because the fuel flying from the edge of the rotating body 30 does not scatter to other places. To be injected into the gap.

The gap between the edge of the rotor 30 and the edge of the fixture 40 is preferably to have a gap of about 2 ~ 20mm. This is because when the gap between the rotor 30 and the fixed body 40 is smaller than 2 mm, the gap between the rotor 30 and the fixed body 40 is difficult, and the gap between the rotor 30 and the fixed body 40 is more than 20 mm. In the wide case, the combustion range is wide and the flame is not concentrated, resulting in poor combustion efficiency.

The upper surface of the fixed body 40 is preferably inclined downward to guide the air supplied from the other end of the air supply pipe 55 to the edge of the rotating body 30.

As such, the liquid fuel dropped from the end of the fuel supply pipe 65 falls along the center of the rotating body 30 and moves along the upper surface 30a inclined upward by the centrifugal force generated while the rotating body 30 rotates. do.

In the present invention, the structure of the upwardly inclined top surface 30a is a very important technical configuration. When the top surface 30a is flat, the fuel spreading direction and the centrifugal force acting direction coincide so that the fuel is easily dispersed. It is not thin and wide evenly spread and thus not finely crushed, resulting in poor combustion efficiency.

However, as shown in the present invention, the upwardly inclined top surface 30a is staggered with the direction in which the fuel flows in the direction in which centrifugal force and gravity act, so that the fuel spreads evenly and very thinly on the top surface 30a and eventually scatters in a very fine particle state. (飛散) It is a structure that must be.

As such, the rotor 30 may maximize the combustion efficiency by scattering the liquid fuel uniformly and very finely, and also may achieve an optimal combustion state due to sufficient air supply by the air supply device.

At this time, as shown in Fig. 6a, the radially linear protrusions 30a are formed on the upper surface 30a of the rotating body 30 in the circumferential direction from the center, or as shown in Fig. 6b. Spiral protrusions 30b may be formed, and may be replaced by grooves instead of the protrusions 30a and 30b so that the dropped liquid fuel may move along the protrusions 30a and 30b, thereby providing stable fuel for combustion. The supply is possible and the vortex diffusion action of the fuel and air ensures a uniform mixing for ideal complete combustion.

The motor 70 is fixed to the frame mounted on the lower side of the housing 10 with a screw, the rotating shaft 30 performs the above functions and to transmit a rotational force transmitted to the rotating body 30 The motor pulley 71 is inserted into the pulley 32, the pulley 32 is fitted to the shaft 31 of the rotating body 30, and the belt 75 connecting the motor pulley 71 and the pulley 32 is connected thereto. do. In this case, the rotating shaft may be supported by a bearing or a bush.

The scattered fuel is ignited by the igniter 80, and the igniter, the motor, the blower, and the like are controlled by a controller (not shown).

The combustion device 100 of the present invention may also be used as a combustion device of a boiler, and the structure of the boiler 200 using the combustion device of the present invention is as follows.

The hot water storage space 19 may be formed with a plurality of flow paths (12, 16) connected to the hot water storage space (19) in the vertical direction in order to increase the heat exchange area.

An example in which a combustion apparatus using the high efficiency combustion apparatus for liquid fuel according to the present invention composed of such components is mounted on a combustion apparatus will be described as follows.

First, the preheater 62, which may be selectively provided, operates by a signal from the controller so that the liquid fuel preheated by the fuel pump is transferred to the other end of the fuel supply pipe 65 so that the upper surface 30a of the rotor 30 may be transferred. The fall to) begins. At the same time, the motor 70, which is powered by the control unit, operates to transmit the rotational force through the shaft 31 through the motor pulley 71, the belt 75, and the pulley 32 in order to rotate the rotor 30. The fuel is scattered while rotating, and the blower 50 operates by the signal of the controller to introduce external air into the combustion chambers 11 and 15 through the air supply pipe 55.

Next, the liquid fuel dropped on the rotating rotor 30 is scattered evenly and thinly spread in the circumferential direction from the center of the rotor 30 by centrifugal force, and the igniter 80 is driven by the ignition signal of the controller. In operation, combustion is started by sufficient air introduced through the air supply pipe 55.

The other end of the soot discharge pipe 20 is configured to be immersed in the water in the water tank 90, so that fine combustion particles or dust is immersed in the water, so that almost water vapor is discharged to the outside, thereby causing an environmental hormone such as dioxin And it can block the source of pollution, it is possible to reduce the noise due to combustion.
