Description

COMBUSTION APPARATUS

The present invention relates to a combustion apparatus, and more particularly, to a combustion apparatus capable of efficiently burning a fuel oil having a relatively high flash point, such as liquid animal or vegetable oil, which is difficult to ignite and has a high viscosity and generates a large amount of tar.

Global warming is accelerating with the increase of carbon dioxide generated by the use of fossil fuels. As fossil fuels become depleted, interest in alternative energy that can replace fossil fuels is increasing.

This interest in alternative energy has led to the term green growth.

Green growth means saving energy and resources, reducing climate change and environmental degradation, making energy self-reliance, clearing the economic crisis through research and development of clean energy and green technology, and creating new growth engines and jobs.

The concept of green growth was first mentioned by the Economist in January 2000 and has become widely used throughout the Davos Forum.

In 2005, the Seoul Initiative for Green Growth was adopted at the Ministerial Conference on Environment and Development in the Asia-Pacific (MECD), and the discussions took place at the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP).

The policy direction for green growth is to reduce greenhouse gas emissions, enhance oil independence and self-reliance, enhance adaptation capacity for climate change (climate change adaptation and energy independence), green technology development and growth engineization, greening of industries and green industry development (The creation of a new growth engine), the creation of green land and green transportation, the green revolution of life, and the implementation of a world-class model of green growth (improving quality of life and strengthening national status).

As the interest in green growth grows, efforts are being made to use environmentally-friendly liquid-phase flora and fauna as fuel for combustion devices, rather than conventional fossil fuels.

In the case of fossil fuels, carbon dioxide is emitted when it is burned, and the emitted carbon dioxide is causing global warming. Of course, vegetable oil also releases carbon dioxide when it is burned. However, when the plant that is the raw material of vegetable oil grows, it absorbs atmospheric carbon dioxide. Therefore, when the vegetable oil burns and the carbon dioxide absorbed when the plant grows, The amount of carbon dioxide produced by the reaction can be regarded as zero.

Despite these advantages, liquid flora and fauna has not been used as a fuel for combustion devices. The reason for this is that in order to use the fuel channel generally, the ignitability should be good, and the viscosity should be low enough to cause swelling. However, the liquid animal or vegetable oil has high ignition point because of high ignitability and high viscosity. In order to use liquid or liquid animal or vegetable oil as a fuel flow channel, it is necessary to process the liquid animal or vegetable oil so as to have a low viscosity, and it is not economical to process liquid or liquid animal or vegetable oil.

Therefore, it is inevitable that development of a combustion apparatus capable of using as a fuel oil without processing a liquid animal or vegetable oil having a high ignition property and a high viscosity is desperately needed.

Also, as the outdoor activities such as camping are continuously increasing, there is an increasing demand for portable stoves using gas, such as "Korean Registered Utility Model No. 20-0268993 (Mar. 03, 2002)". However, the conventional portable stove has a problem that it can be used only for the purpose of cooking or heating food, and can not be used for other purposes.

And FIG. 4 is an internal perspective view of a combustion apparatus according to an embodiment of the present invention.

1 to 4, the combustion apparatus 10 according to an embodiment of the present invention may include an upper body 10a and a lower body 10b. The upper body 10a and the lower body 10b are vertically coupled to each other and can be detached. The upper main body 10a includes a combustor 100 for supplying and burning fuel and the lower main body 10b may include a blower 200 for supplying air to the combustor 100. [ Therefore, the fuel supplied to the combustor 100 can be easily burned by the air supplied through the blower 200. [ The upper portion of the upper main body 10a is further provided with a grill 30 for supporting various containers for cooking food so that the thermal power can be safely transferred to the container. 20 can be provided to support the lower main body 10b. At this time, the combustion apparatus 10 can be easily used even on uneven surfaces separated by a predetermined distance from the ground by the support base 20, and it is possible to prevent the lower main body 10b from being damaged or damaged by touching the ground.

The upper body 10a is detachably coupled to the upper portion of the combustor 100 and includes a heating means 300 for completely burning incompletely burnt air in the combustor 100 and a portion of air supplied from the blower 200 And a generator means 400 for generating an electromotive force by a temperature difference.

The heating means 300 includes a ceramic 310 which reheats the incompletely burnt gas in the combustor 100 and completely burns the incompletely burnt gas and a ceramic 310 which is extended from one end of the ceramic 310 to allow the user to remove the heating means 300 from the combustor 100 It is possible to have a handle 320 that can be held as far as possible.

The ceramic 310 may have a ring shape having a discharge port 312 formed at the center thereof and may have a step 311 formed at an edge thereof so as to be seated on the upper end of the combustor 100.

The outer diameter of the upper portion of the ceramic 310 may be larger than the outer diameter of the lower portion of the ceramic 310 to form the step 311. [ Thus, the lower part of the ceramic 310 is inserted into the combustor 100, and the upper part of the ceramic 310 is over the upper part of the combustor 100.

The size of the discharge port 312 formed in the ceramic 310 is much smaller than the size of the opening formed in the upper portion of the combustor 100 so that the gas discharged from the combustor 100 mostly comes in contact with the ceramic 310 And may be discharged through an outlet 312 formed in the ceramic 310.

Since the ceramic 310 is placed in the upper part of the combustor 100 and then heated, the gas discharged from the combustor 100 is once heated by the radiant energy radiated from the ceramic 310, Thereby completely burning the gas.

Therefore, the liquid animal or plant oil can be completely burned even when the fuel flow path of the combustion apparatus 10 is used, so that the amount of tar generated upon incomplete combustion can be reduced.

The combustion wick 330 is formed of a mesh having a perforated hole, 331 may be combined. The combustion wick 330 coupled to the wick support frame 331 is spirally wound and detachably coupled to the combustor 100. The combustion wick 330 is spirally wound so that a certain space is formed in the combustion wick 330 and the thermal decomposition of the high temperature gas can be smoothly performed in the space formed between the combustion wick 330. [ In addition, since the combustion wick 330 is detachably coupled to the combustor 100, the combustion wick 330 can be easily replaced when the combustion wick 330 is to be replaced for a long time.

The extension 340 may extend upward in the combustion wick 330 to engage the handle 320. Accordingly, the combustion wick 330 can be easily pulled out of the combustor 100 by using the handle 320. Although the extension 340 is shown coupled to the handle 320 and pulls the combustion wick 330 out of the combustor 100 using the handle 320, So that the combustion wick 330 can be pulled out of the combustor 100 by gripping the extended portion 340 with a forceps (not shown) or the like.

The power generation means 400 may include a thermoelectric module 420 and a cooling plate 410. Generally, a thermoelectric element is a generic name of a device that uses various effects that are caused by the interaction of heat and electricity. A thermistor, which is a device using temperature change of electric resistance, a device using Jeff Beck effect, which is a phenomenon in which electromotive force is generated by temperature difference, and a Peltier device using Peltier effect, which is a phenomenon in which heat is absorbed .

Particularly, the Hebeck effect is a phenomenon in which an electromotive force is generated when the two ends of two kinds of metals are connected to each other at different temperatures. In the present invention, one surface of the combustor 100 is heated by the combustion of the fuel supplied to the combustor 100 100 and the thermoelectric element plate 420 which is brought into contact with the cooling plate 410 having a low temperature on the other surface. Therefore, unlike conventional portable stoves, which can be used mainly for cooking or heating food, it can be used for electric power supply of electronic products such as charging a battery of a mobile phone by producing electric power, so that it is more effective in outdoor activities such as camping Can be used.

The lower main body 10b may include a battery 500 connected to the power generating means 400 and storing the electric power generated by the power generating means 400. [ Accordingly, electric power can be used separately from the combustion operation of the fuel, so that it is unnecessary to burn the fuel unnecessarily to generate electricity.

The battery 500 is connected to the PCB 600 and the PCB 600 is operated by the power stored in the battery 500. The USB port 800 formed on the side surface of the lower body 10b, So that the electronic product inserted into the USB port 800 and the battery 500 can be electrically connected to each other.

The projecting portion 900a of the plate 900 and the support plate 1000 may be respectively provided with through holes 910 and 1010 serving as passages through which the air discharged from the blower 200 moves to the combustor 100 . The protrusions 900a and the support plate 1000 are provided with the through holes 910 and 1010 so that the air discharged from the blower 200 can be easily supplied to the combustor 100. [

The following will describe the combustor 100 in more detail. In the following description, only different parts from the above-described embodiment will be described in detail and the same or similar parts will not be described in detail.

5 is a view illustrating a combustor of a combustion apparatus according to an embodiment of the present invention.

1 to 5, a combustor 100 of a combustion apparatus 10 according to an embodiment of the present invention includes an inner wall 100a forming a combustion chamber 110 and an air supply chamber 120 formed on the outer wall 100b. The top plate 100c may be continuously connected to the inner wall 100a and the outer wall 100b at an upper end of the air supply chamber 120 formed between the inner wall 100a and the outer wall 100b.

The combustion chamber 110 in which the fuel is received may be provided in a cylindrical shape having an open top. In this embodiment, the combustion chamber 110 has a cylindrical shape. However, the combustion chamber 110 may have various shapes such as a polygonal shape as well as a cylindrical shape.

Fuel oil such as liquid animal or vegetable oil is supplied to the combustion chamber 110 and air discharged from the blower 200 can be supplied to the air supply chamber 120 so that the fuel supplied to the combustion chamber 110 is efficiently burned.

A fuel supply port 140 is formed on the side surface of the inner wall 100a forming the combustion chamber 110 to supply the fuel oil to the combustion chamber 110 and extends from the fuel supply port 140, The fuel supply pipe 160 is provided with a fuel adjusting device 161 for adjusting the amount of fuel flowing into the combustor 100 . At this time, the fuel supply pipe 160 may be integrally formed with the inner wall 100a by welding or the like.

An air inlet 150 is formed at the lower end of the air supply chamber 120 so that the air passing through the through holes 910 and 1010 can be supplied to the air supply chamber 120 through the blower 200.

As described above, by introducing air into the combustion chamber 110, it is possible to rapidly ignite the combustion wick 330 installed in the combustion chamber 110. In addition, by supplying sufficient air into the combustion chamber 110, it is possible to prevent incomplete combustion of fuel such as liquid animal or plant oil with high viscosity.

When air is supplied from the blower 200 to the combustion chamber 110, the air supplied from the blower 200 is first supplied to the air supply chamber 120 through the air inlet 150, and then the air inside the air supply chamber 120 Can be dispersed and supplied to the combustion chamber 110.

A plurality of air holes 130 may be formed in the inner wall 100a to improve the combustion efficiency in the combustion chamber 110 when the air supplied to the air supply chamber 120 is dispersed and supplied to the combustion chamber 110. [ have.

At the bottom of the inner wall 100a, a primary combustion air hole 131 for supplying air for primarily burning the fuel in the combustion chamber 110 may be formed. At this time, the primary combustion air hole 131 may be formed at a position that is 1/2 or less of the height of the combustion chamber 110. And may be formed at a predetermined distance from the bottom of the combustion chamber 110. When air is supplied into the combustion chamber 110 through the primary combustion air hole 131, the air circulates along the inner wall surface of the combustion chamber 110 and flows through the primary combustion air hole 131 at a position lower than the lower end of the primary combustion air hole 131 . Accordingly, air can be supplied to the combustion wick 330 located inside the combustion chamber 110, so that the fuel oil absorbed in the combustion wick 330 can be readily ignited. In addition, by continuously supplying air to the ignited combustion wick 330, the fuel oil absorbed in the combustion wick 330 can be thermally decomposed.

The upper portion of the primary combustion air hole 131 may be provided with a secondary combustion air hole 132 for supplying air for secondary combustion of the primary combusted fuel. At this time, the secondary combustion air hole 132 may be formed at a position that is more than 1/2 of the height of the combustion chamber 110.

On the other hand, the secondary combustion air holes 132 may be formed in the direction facing the primary combustion air holes 131 and in the side direction facing the primary combustion air holes 131. The reason why the secondary combustion air holes 132 are formed in the direction in which the primary combustion air holes 131 are not formed is that the vortexes are generated in the combustion chamber 110, So that the air inside the combustion chamber 110 can be circulated evenly.

The pyrolysis layer D may be formed in the lower portion of the combustion chamber 110 and the combustion layer C may be formed in the upper portion of the combustion chamber 110. [

The thermal decomposition layer (D) is a layer in which the fuel oil absorbed in the combustion wick (330) made of a ceramic fiber is decomposed by heat. The combustion process in the pyrolysis layer (D) will be described. The fuel oil flowing through the ceramic fiber burning wick (330) is heated to lower the viscosity. The fuel oil having a lower viscosity is heated by the capillary phenomenon As shown in FIG. As the temperature of the combustion core 330 increases, the fuel oil is easily pyrolyzed in the pyrolysis layer (D), so that heat recirculation between the combustion core (330) of the ceramic fiber material and the combustion flame is performed, The supply forms a hot flame.

The fuel oil pyrolyzed in the pyrolysis layer (D) by the air supplied from the primary combustion air hole (131) is converted into gas and supplied to the combustion layer (C). The combustion layer C is a layer in which a hot gas is burned. The hot gas supplied from the pyrolysis layer D is mixed with air supplied from the secondary combustion air hole 132, and then burned. Therefore, fuel such as liquid or liquid animal or vegetable oil having high viscosity can be completely combusted and the amount of tar generation can be reduced.

On the inner circumference of the upper side of the inner wall 100a forming the combustor 100, a flame alignment air hole 133 may be formed at a predetermined interval in the circumferential direction. The flame alignment air holes 133 serve to align the flames ejected from the combustor 100 to the center.

Since the primary combustion air hole 131 and the secondary combustion air hole 132 are formed in the combustor 100, the flame does not rise in the vertical direction and is not ejected from the combustor 100, . In order to prevent the flame from being ejected in an oblique direction as described above, air is injected toward the central portion of the combustor 100 through the air hole 133 for flame alignment just before the flame is ejected from the combustor 100, ) In the center of the flame.

Hereinafter, the blower 200 will be described in more detail. In the following description, only different parts from the above-described embodiment will be described in detail and the same or similar parts will not be described in detail.

6 is a perspective view illustrating a blower of a combustion apparatus according to an embodiment of the present invention.

1 to 6, a blower 200 of a combustion apparatus 10 according to an embodiment of the present invention includes a discharge unit 211 for discharging air to the combustor 100, And a plurality of blades 221 provided on one side of the side wall 212 and coupled with the first body 210. The first body 210 has a plurality of blades 221, And a suction unit 231 which is coupled with the first body 210 to seal the inside of the side wall 212 and allows the air to be easily sucked by the rotational force of the fan 220 is formed And a second body 230 may be provided.

The fan 220 may be connected to the motor 240 to generate a rotational force by the force of the motor 240. In addition, the plurality of blades 221 may be formed to have curved surfaces in the same direction and to maintain a constant interval. Accordingly, the air can be sucked along the curved surface by the rotational force of the fan 220 through the suction portion 231 of the second body 230. Since the inside of the side wall 212 is sealed by the side walls 212 and the second body 230 except for the discharge portion 211, the air sucked by the fan 220 is discharged through the discharge portion 211 Can be discharged.
