Description

Combustion apparatus to maximize thermal efficiency

The present invention relates to a combustion device of a boiler using combustion waste generated from wood or other rural areas. In particular, when the combustion device is first ignited, an oil boiler ignition device or a gas boiler ignition device is used. When the fuel is ignited and the fuel is injected into the combustion apparatus, the fuel is rotated by the rotational force of the screw so that the fuel is introduced into the combustion unit in the smallest order. After the combustion, the discharge port of the combustor is spirally formed at the top of the combustor. In the present invention relates to a combustion device to maximize the combustion efficiency by allowing the combustion of sparks or heat to vortex causing combustion.

Generally

In general, boilers mainly use gas or petroleum as fuel, and in places such as vinyl houses, where fuel consumption is high, it is not practical due to excessive spending of fuel, so solid fuel such as wood or coal is not used. In the case of the boiler using a solid fuel, the ignition part is formed in the lower part of the fuel container, and the upper part of the fuel container is provided with the communication which discharges the gas which is generated when it burns. It has a structure equipped with a hot water circulation pipe on the outside of it, and when the solid fuel such as logs or coal is inserted into the fuel container and ignited in the ignition part, the fire is generated while burning the solid fuel. The generated gas is discharged through the flue, which is generated when burning solid fuel. The hot water is heated by circulating the hot water circulation pipe provided around the outside of the fuel tank by the high temperature to obtain hot water, and the hot water is heated while circulating the inside of the plastic house or the vents. The tuyere is formed.

Therefore, the boiler using the solid fuel as described above has a hassle to continuously input the solid fuel compared to the oil boiler or gas boiler, but can be obtained relatively easily, such as twigs, logs and coal, and can be obtained at a low price Since the use of fuel is helpful to the heating costs of the farmhouse, it is widely spread.

However, in the boiler using the solid fuel as described above, when the solid fuel is put into the fuel container and then ignited in the ignition unit to combust the solid fuel, the lower part of the solid fuel is not burned due to the natural phenomenon in which the spark rises. As the upper part of the solid fuel is also burned by the rising flame, more thermal power is required, and thus, the combustion of the fuel more than necessary causes the disadvantage of increasing the consumption of the solid fuel, and a large amount of heat can be obtained after the solid fuel is injected. However, as time goes by, the amount of solid fuel is consumed to some extent, and a waste end that has a disadvantage of lowering the amount of heat is generated, and when the solid is combusted, the flame rises and is discharged through the communication provided at the top of the fuel tank, thereby consuming waste heat. Many problems have arisen and are not completely burned when burning solid fuel? The problem of the environmental pollution was generated is released.

In order to solve the above problems, the upper part of the fuel container is sealed and a plurality of air vents are formed at the lower part of the fuel container in which the ignition unit is located, and air is introduced through the blower to discharge the air through the discharge hole. When the solid fuel inserted into the fuel container is combusted by the ignition unit, the flame is raised to burn the upper portion of the solid fuel instead of burning the upper part of the solid fuel. The applicant filed a utility model registration application No. 1 of the present application to minimize the combustion of the solid fuel to be discharged through the discharge communication formed on the lower side of the boiler through the fire circulation circulation passage provided in the circulation part. The design of the first application is to keep the fuel container closed and By forming a vent hole through which the air introduced into the air is discharged so that the fire is discharged through the vent hole, when the solid fuel is combusted, the fire is raised and the entire solid fuel is prevented from being burned in a short time. It is possible to easily predict the fuel input time by burning the fuel for a long time, and it is possible to prevent the deterioration of thermal efficiency as well as preventing the fire efficiency generated by burning solid fuel from being discharged into the exhaust pipe. When combusting, the pollutants generated by incomplete combustion are recirculated and combusted, which has the advantage of preventing environmental pollution by discharging the completely combusted materials, but has the disadvantage of not being able to use fuel such as small pieces. There are disadvantages that have limitations.

The present invention is designed to solve the problems caused in the conventional boiler combustion apparatus as described above, when the first ignition of the flame in the combustion device is ignited through a separate ignition device, such as an oil boiler or gas boiler, When fuel is injected into the combustion part of the combustion device, it is supplied through a screw, but rotates inside the combustion chamber to allow small particles to be introduced, and large particles are to be injected as they are burned through the input to enable complete combustion of the fuel. In the upper part of the combustion device, a combustion device is provided to maximize the thermal efficiency by forming a discharge outlet of light weight of the burned fuel and a discharge outlet of heat generated by the combustion of the fuel separately. I would like to.

Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention in detail as follows.

In the combustion device (2) is formed in the center of the main body (1), one side is formed with an inlet () for injecting ignition and fuel, and in the lower combustion device formed with an outlet (7) for discharging the digested ash,

A fuel input unit 3 configured to spirally input a solid fuel obtained by fueling wood, sawdust or waste into the combustion chamber 2 in the center of the main body 1 at the lower part of the main body 1, and formed at the center of the main body 1; An ignition unit 4 is formed in the combustion chamber 2 to ignite the fuel introduced through the fuel inlet unit 3 through the fuel inlet unit 3 and to ignite the liquid fuel such as oil, and a combustion chamber 2 is formed below the main body 1. In order to discharge the ash of the solid fuel burned in the) ash outlet (5), the communication connection portion 6 for transmitting the heat generated by burning the solid fuel in the combustion chamber (2), and in the combustion chamber (2) The specific gravity of the combusted solid fuel is made of a small discharge port 7 for discharging the elevated ash with the heat to the outside.

In this case, as shown in FIG. 2, the fuel inlet 3 is formed in a shape in which the fuel passage 11 spirally surrounds the main body 1, and a fuel having small particles is preferentially provided on the bottom surface of the fuel passage 11. The fuel insertion holes 14 are arranged at regular intervals so as to be introduced into the combustion chamber 2, and a fuel inlet 12 for inserting fuel into one side of the fuel inlet 3 is formed. The inside is provided with a feed screw 13 to smoothly inject fuel.

The ignition unit 4 communicates with the combustion chamber 2 provided at the center of the main body 1 at one lower side of the main body 1 and has a separate ignition means using oil or gas from the outside. (2) Combustion of the fuel injected into the inside, and when there is no fuel to be burned in the combustion chamber (2) through the ignition unit (4) is to input the oil or gas, not the solid fuel to be burned.

In addition, the ash discharge port 5 formed in the lower part of the main body 1 discharges ash generated when the fuel is combusted in the combustion chamber 2 to the outside. When the fuel is completely combusted in the combustion chamber 2, the ash having a high specific gravity is combusted. The ash is discharged to the ash outlet 5 without rising by the heat, and the ash is discharged to the outside by the discharge screw 15 provided in the ash outlet (5).

In addition, the communication connecting portion 6 and the outlet 7 formed at the upper portion of the main body 1 heat transfer the heat generated by burning the fuel in the combustion chamber 2 to the outside, or the specific gravity generated by burning the fuel is small As for discharging the ash, the communication connecting portion 6 is formed in the upper center of the main body 1 to be in direct communication with the combustion chamber 2 to be connected to the external communication, the discharge port 7 of the main body 1 A spiral discharge passage 16 is formed in the upper portion to discharge ash, but when the communication connecting portion 6 is closed, heat is also discharged through the discharge port 7 by burning the fuel in the combustion chamber 2 to ascend. The hot air is to cause the vortex phenomenon inside the body (1), so that the combustion is made to enable the complete combustion of the fuel.

Referring to the operation of the present invention configured as described above are as follows.

After inserting a small amount of fuel such as oil or gas through the ignition unit 4 provided on one side of the lower part of the main body 1 and igniting the fuel inserted through the ignition unit 4, wood chips, sawdust or wastes are When the fuel is molded into fuel and the solid fuel in the form of small pieces is inserted into the fuel inlet 12, the solid fuel is inserted into the fuel inlet 3 by the injection screw 13 provided in the fuel inlet 12. When the solid fuel introduced into the fuel inlet 12 is continuously introduced by the continuous movement of the input screw 13, the solid fuel is inserted while being pushed into the fuel passage 11 of the fuel input unit 3 and the fuel passage is inserted. A plurality of fuel insertion holes 14 are formed in the bottom surface of the 11, and the fuel passage 11 is spirally formed in the main body 1, and the width thereof becomes narrower gradually. Fuel formed in the bottom surface of the furnace 11 The solid fuel, which is inserted into the combustion chamber 2 through the insertion hole 14 and has a large particle, is inserted into the combustion chamber 2 while continuously proceeding.

Therefore, the solid fuel inserted into the combustion chamber 2 is already ignited through the ignition unit 4 in the combustion chamber 2 through the fuel injection unit 3 as described above. This combustion flame rises and the particles of the solid fuel moving to the fuel passage 11 become smaller by burning the solid fuel having a larger particle moving through the fuel passage 11 without being injected into the combustion chamber 2 yet. The solid fuel that is inserted into the fuel insertion hole 14 and not dropped into the fuel insertion hole 14 is finally inserted into the combustion chamber 2 while continuing.

Therefore, the solid fuel combusted in the combustion chamber 2 is not burned all at once, but is gradually burned by a constant amount of the solid fuel, which is caused by the combustion of the solid fuel, and is caused by the combustion of the solid fuel in the combustion chamber 2. The heavy ash of the combusted solid fuel is not affected by the flame rising from the combustion chamber 2 and falls to the ash outlet 5, and the ash of the solid fuel with a small specific gravity is raised like the flame of the combustion chamber. Ash dropped in the discharge port (5) is discharged to the outside through the discharge screw (15) provided in the ash discharge port (5), the raised ash, such as flame is discharged to the discharge port (7) provided on the upper portion of the main body (1) Will be.

At this time, since the discharge passage 16 of the spiral shape is formed in the upper portion of the main body 1, the heat or ash generated in the combustion chamber 2 causes the vortex phenomenon inside the main body 1. When the communication is connected to the communication connecting portion 6 formed on the upper part of the main body 1, the heat generated while burning the solid fuel in the combustion chamber 2 is heat transferred to the outside through the communication. When the connection part 6 is closed, the heat generated in the combustion chamber 2 is discharged to the outside through the discharge port 7 so that the heat generated while burning the solid fuel in the combustion chamber 2 communicates with the connection part 6 or the discharge port 7. It can be used optionally.

As such, the present invention does not input a large amount of fuel at a time when the fuel is injected into the combustion chamber, but the small particles are introduced through the fuel insertion hole, and the large particles are gradually burned by the flame generated in the combustion chamber. The fuel is completely burned by reducing the particle size into the combustion chamber, and the ash of the solid fuel burned in the combustion chamber has a high specific gravity and is discharged through the ash outlet provided below the main body. As it rises as described above and is discharged to the outlet formed spirally in the upper portion of the main body, the flow of air in the combustion chamber is able to have a high temperature due to the vortex phenomenon such as vortex phenomenon occurs.
