Description

Combustion apparatus to maximize thermal efficiency

The present invention relates to a combustion apparatus of a boiler using combustion waste generated from wood or other rural areas, and in particular, when igniting the combustion apparatus for the first time using an ignition apparatus of an oil boiler or an ignition apparatus of a gas boiler. 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.

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 as described above, in the case of a 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 a communication for discharging the gas generated when burning. 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, and the high gas generated when burning solid fuel By heating the hot water circulation tube provided around the outer side of the fuel container by heat to obtain hot water, the hot water is heated while circulating the hot water inside the vinyl house or the vents, and at this time, an air outlet for supplying air necessary for combustion to the outer circumferential surface of the ignition unit. 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. Since 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. Many problems have arisen and when burning solid fuel there is a gas that is not completely burned. Exodus is a problem of environmental pollution has occurred.

In order to solve the above problems, the upper part of the fuel container is sealed and a plurality of air vents are formed in the lower part of the fuel container in which the ignition unit is located so that air is introduced through the blower and discharged through the discharge hole. When the ignition unit burns the solid fuel inserted into the fuel container, the flame is not raised to burn the upper portion of the solid fuel, but is discharged through the discharge hole to heat the hot water circulation unit provided at the outside of the fuel container, and the heat is provided in the hot water circulation unit. The applicant filed a utility model registration application No. 99-720 with the boiler to minimize the combustion of the solid fuel which is to be discharged through the discharge communication formed on the lower side of the boiler through the fire circulation passage. The design of the first application encloses the fuel container and flows into the boiler at the bottom of the fuel container. By forming a vent hole through which the gas is discharged, the fire is discharged through the vent hole so that 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 allows for a long time to make the fuel input time easy to predict, and not only does not prevent the fire generated by burning solid fuel to be discharged into the exhaust pipe and lower thermal efficiency, but also incomplete combustion when burning solid fuel. It has the advantage of preventing environmental pollution by releasing the completely burned material because it recycles and burns the pollutant generated by This occurred.

The present invention has been invented to solve the problems occurring 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 a 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. It is for that purpose.

Hereinafter, the configuration and operation of the present invention will be described in detail by the accompanying drawings.

In the present invention, the combustion chamber (2a, 2b) is formed in the center of the main body 1, one side is formed with an inlet for the ignition and fuel is injected, the upper combustion apparatus having a discharge port (7) for discharging the digested ash And a fuel input unit 3 and a main body 1 in which a solid fuel obtained by fueling wood, sawdust or wastes into the lower part of the main body 1 is spirally fed into the lower end of the combustion chamber 2b in the center of the main body 1. An ignition section 4 for igniting a liquid fuel such as oil to ignite the fuel introduced through the fuel injection section 3 into the combustion chamber 2a formed at Ash discharge port 5 for discharging the ash of the solid fuel burned in (2a, 2b), and a communication connection (6) for transmitting heat generated by burning solid fuel in the combustion chamber (2a, 2b) to the outside; Low specific gravity of solid fuel burned in the combustion chamber (2a, 2b) It has been made in a material with an elevated opening in the outlet (7) for discharging 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 formed on the bottom surface of the fuel passage 11. Fuel insertion holes 14 are arranged at regular intervals so that the fuel injection holes 14 are first injected into the combustion chamber 2b, and a fuel inlet 12 for inserting fuel into one side of the fuel inlet 3 is formed. ) Is provided with an input screw 13 to smoothly inject fuel.

The ignition unit 4 communicates with the combustion chamber 2a 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. (2a) When the fuel injected into the interior is to be combusted, and when there is no fuel to be burned in the lower ends of the combustion chambers 2a and 2b, the ignition section 4 is supplied with oil or gas instead of solid fuel to combust.

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 chambers 2a and 2b to the outside. When the fuel is completely burned in the combustion chambers 2a and 2b, the specific gravity The large ash does not rise by the heat of combustion and falls to the ash discharge port 5, and the ash is discharged to the outside by the discharge screw 15 provided in the ash discharge port 5.

In addition, the communication connecting portion 6 and the outlet 7 formed at the upper portion of the main body 1 may transfer heat generated by burning fuel in the combustion chambers 2a and 2b to the outside, or specific gravity generated by burning fuel. As for discharging the small ash, the communication connecting portion 6 is formed in the upper center of the main body 1 so as to be in direct communication with the combustion chambers 2a and 2b so as to be connected to the external communication, and the outlet 7 is the main body. A spiral discharge passage 16 is formed on the upper portion of the upper portion to discharge the ash, but when the communication connecting portion 6 is closed, the heat is discharged through the discharge port 7 together with the combustion chambers 2a and 2b. In the heat rising by burning the fuel in the combustion causing the vortex phenomenon inside the main body (1) 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 Ipgong 14 is inserted to the bottom of the combustion chamber (2b) through which particles will be inserted to the bottom of the combustion chamber (2b), while proceeding with a large solid fuel continuously.

Accordingly, the solid fuel inserted into the lower end of the combustion chamber 2b through the fuel input unit 3 is already inserted into the lower end of the combustion chamber 2b since the solid fuel is already ignited through the ignition unit 4 in the combustion chambers 2a and 2b. The solid fuel is combusted and the combustion flame rises and is not yet introduced into the combustion chamber 2b, but the solid fuel moving to the fuel passage 11 is burned by burning the solid fuel having large particles moving through the fuel passage 11. As the particles become smaller and smaller, the fuel is inserted into the fuel insertion hole 14 and the solid fuel not dropped into the fuel insertion hole 14 is continuously inserted into the lower end of the combustion chamber 2b.

Therefore, the solid fuel combusted in the combustion chambers 2a and 2b is not burned all at once but gradually burned by a constant amount being injected into the lower end of the combustion chamber 2b so that the solid fuel is completely burned, and the solid fuel is the combustion chamber 2a. , The heavy ash of the combusted solid fuel generated by the combustion in the 2b) is not affected by the flame rising from the combustion chamber (2a, 2b) through the mesh 20 formed at the bottom of the combustion chamber (2a, 2b) Ash of the solid fuel falling into the discharge port 5 and having a small specific gravity rises like a flame in the combustion chambers 2a and 2b, and the ash dropped in the ash discharge port 5 is discharge screw 15 provided in the ash discharge port 5. The discharged to the outside through), the ash, such as the flame is discharged to the discharge port 7 provided on the upper portion of the main body (1).

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 chambers 2a and 2b causes vortex phenomena 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, heat generated while burning the solid fuel in the combustion chambers 2a and 2b is transferred to the outside through the communication. When the communication connection part 6 is closed, the heat generated in the combustion chambers 2a and 2b is discharged to the outside through the discharge port 7, so that the heat connection generated while burning the solid fuel in the combustion chambers 2a and 2b is communicated. (6) or can be selectively used as the outlet (7).

As described above, 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 spark 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 on the upper portion of the main body, the air flow may have a high temperature due to the vortex phenomenon such as the flow of air in the combustion chamber.
