Description

Technical Field [0001] The present invention relates to a solid fuel using oak,

More particularly, the present invention relates to a solid fuel using an oak, and more particularly, to a method for manufacturing a solid fuel using an oak, The present invention relates to a solid fuel using an oak and a method for producing the solid fuel, which is capable of easily igniting and completely burning owing to the nature of the ring and not allowing the fermentation alcohol to easily volatilize during the distribution process.

Generally, solid fuel made of materials such as charcoal, firewood, and briquettes is difficult to carry or store due to the characteristics of materials, and is liable to be broken during handling, and is inconvenient when camping.

In addition, since conventional solid fuels are difficult to self-ignite, an ignition means such as a lightning bolt is used. In the case of a lightning bolt, in addition to the additional cost, it is a reality that the use of the heavy metal component contained in the lightning is avoided.

In order to solve the above problems, a solid fuel produced by molding a material such as sawdust into a certain shape has been partially disclosed. However, the solid fuel made of sawdust or the like is easy to carry, store and handle, and is easily ignited as compared with the conventional solid fuel, but still has a limitation that a separate ignition means such as a lightning bolt must be used.

In addition, in order to produce the solid fuel from the sawdust or the like, a complicated process such as cutting and pressing of the wood must be performed. This causes not only the productivity of the product but also the price to rise.

On the other hand, the conventional solid fuel is difficult to completely burn the whole of the solid fuel, so that even if the ignited flame is turned off, a part of the solid fuel remains unburned.

In addition, when a conventional solid fuel is burned, a large amount of smoke and ashes may be generated, thereby harmful components to the human body may enter the body through the respiratory system, and air pollution may occur. In addition, Lt; / RTI >

FIG. 5 is a view illustrating a procedure of manufacturing a solid fuel using an oak according to a second embodiment of the present invention.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

According to an embodiment of the present invention, the solid fuel (1) according to the present invention is a solid fuel base (100) made of oak which is light and combustible as an environment-friendly material for easy storage and transportation in the outdoors such as camping, ).

Since the oak which is a raw material of the solid fuel (1) is a hard wood which is hard, hard and does not easily decay, including oak, oak, oak, and oak, (1).

In addition, oak does not emit harmful substances to the human body during combustion, and can generate and emit far-infrared rays, which is a substance beneficial to the human body.

The solid fuel base 100 may be formed as a cut wood having a thickness of 1-5 cm by using a cutter in a direction perpendicular to the longitudinal direction of the wood, The upper and lower surfaces of the solid fuel base 100 thus formed are flat.

In this case, the solid fuel base 100 is formed to have a thickness of 1-5 cm for a sufficient thermal power when burning. When the solid fuel base 100 is formed to be less than 1 cm, the solid fuel base 100 is burned in a short time If it is formed over 5cm, the fermentation alcohol can not permeate to the inside, so it can not burn to the inside when burning and can not become charcoal.

The solid fuel base 100 may be cut radially in a radial direction with reference to the depth 110 of the solid fuel base 100 to form the fuel chip 200 having the radius surface 210 formed therein The radiused surface 210 may be formed by cutting along the shape of a tree and may be formed not to be flat.

In other words, the solid fuel base 100 is cut in a direction perpendicular to the longitudinal direction of the tree, and the tree is cut in the form of a tree so that a straight line pattern of the rings appears. Thus, the solid fuel base 100 ) Can be used without discarding, and it is possible to prevent deformation of the wood.

In addition, the fuel chip 200 can be cut differently depending on the diameter of the solid fuel base 100. Since the diameters of the circle, chest, and tail portions of the log are different from each other, It is desirable to do differently.

Here, the fermentation alcohol is permeated into the fuel chip 200, so that the solid fuel 1 can be easily ignited without any additional ignition material, and the entire combustion can be performed.

In the present invention, as the volatile agent for ignition, a fermentation alcohol, which is harmless to the human body, is used, and the solid fuel base 100 (100) is used as the volatile agent, since formaldehyde, which is harmful to the human body, ) Or the fuel chip 200 is immersed in the fermentation alcohol as such a volatile agent.

That is, the fermentation alcohol is allowed to penetrate deeply into the solid fuel base 100 or the fuel chip 200 to be able to ignite, and the fermentation alcohol is preferably ethanol alcohol of about 96% alcohol, The invention is not limited thereto.

When the fermentation alcohol permeates the solid fuel base 100 or the fuel chip 200, the fermentation alcohol penetrates deeply into the solid fuel base 100 or the ring-shaped portion formed in the fuel chip 200, The fermented alcohol penetrated by it is not easily volatilized.

Specifically, the fermentation alcohol permeates into a portion of the solid fuel base 100 or the fuel chip 200, which is composed of a ring-shaped structure between the ring and the ring that is firmly formed in the structure, and most of the fermentation alcohol The solid fuel base 100 or the fuel chip 200 according to the present invention is surrounded by the ring-shaped structure by the ring, so that the fermentation alcohol is not easily volatilized, and the fermentation alcohol Volatilization can be minimized.

Particularly, when the solid fuel base 100 or the fuel chip 200 according to the present invention is packaged as a final product, the packaging paper uses a silver foil or the like. The solid fuel base 100 or the solid fuel base 100, Both side surfaces cut by the cutter of the fuel chip 200 are brought into contact with each other so that substantially both sides of the solid fuel base 100 or the fuel chip 200 are blocked by the wrapping paper and the other part is blocked by the ring, Volatilization is minimized.

Such non-polar ethyl alcohol, which is a fermentation alcohol, can be obtained mainly by fermenting potato or corn.

Meanwhile, the solid fuel according to the present invention can cause a spark of a desired color in the combustion process as an event. To this end, the solid fuel according to the present invention may contain copper and strontium as the fermentation alcohol.

The mixing ratio of these is 20% by weight of copper per 100 g of fermentation alcohol. If the amount of copper is less than 5%, there is a problem that the color of the flame is not good. If the amount of copper is 20% or more, the production cost is increased and the purchase cost of the consumer is increased. Likewise, it can be mixed at a ratio of 20% by weight of strontium per 100 g of the fermented alcohol. If the strontium content is less than 5%, the color of the flame may not be good. If the content is more than 20% There is a problem of increasing.

The ferric alcohol and the copper sulfate impregnated into the fuel chip 200 and the fine particles of the strontium react when burning the solid fuel 1 to exhibit a color. Specifically, when the copper sulfate is added, And when the above strobilur is added, a red flame is emitted. Therefore, considering the fact that the general flame is yellow, it is possible to make a flame having various colors by the combination of these. This can be used for events on special days.

3, the sedimentation tank 400 is provided with a circulation device 500 below the sedimentation tank 400 to prevent the ferrous sulfate mixed with the fermentation alcohol and the stratospheric fine particles from sinking downward. do.

At this time, the radially cut fuel chip 200 may have a fan shape. The fuel chip 200 is cut with reference to the water depth 110 of the solid fuel base 100, so that the fan- (140), the ornamental material (130), and the bark (120).

The core material 140 is a part close to the water depth 110 and has a small water content but is formed with a dense chain and has the greatest shrinkage percentage and the percolation material 130 is a part of the core material 140 and the bark 120 And the shrinkage percentage is lower than that of the core material 140. The bark 120 is a part of the skin.

Since the core material 140, the sapwood 130, and the bark 120 are all contained in the radial direction, the ring is cut in the horizontal direction, and when the dough is immersed in the fermented alcohol due to the solid structure of the ring, When the alcohol penetrates deeply into the interior of the fuel chip 200, it may not easily volatilize. The radial surface 210 is formed to be short to prevent the fermentation alcohol from easily volatilizing, It is easier to ignite because the part is included.

In addition, when the solid fuel 1 is ignited and burned, it can be used with strong thermal power due to the percolation material 130 and the bark 120. When the burning of the bark 120 and the material 130 is completed The core member 140 having a high shrinkage ratio can maintain a constant temperature thermal power for a long time.

In addition, when the fuel chip 200 is infiltrated into the fermentation alcohol, the surface where the bark 120 is formed so that the fermentation alcohol can penetrate deeply into the interior of the fuel chip 200 The groove 300 may be formed on the other surface. The grooves here include holes as well as the grooves shown in the figures.

The grooves 300 may be formed in the state of the solid fuel base 100 or may be formed in the state of the fuel chip 200, but are not limited thereto.

By forming the groove 300, the fermentation alcohol can permeate into the interior of the solid fuel 1, and the air is introduced in the combustion process, so that a part of the fuel chip 200 is not left at the time of combustion, Can play a role.

The grooves 300 are preferably formed in the lateral and longitudinal directions on the upper and lower surfaces of the solid fuel base 100 or the fuel chip 200 for easy penetration of the fermentation alcohol, The grooves 300 may be formed in the vertical or horizontal direction on the radial surface 210 of the heat radiating plate 210, but the present invention is not limited thereto.

The grooves 300 may be formed differently depending on the size of the solid fuel base 100 or the fuel chip 200 and may be formed in the solid fuel base 100 or the fuel chip 200 As shown in FIG. 2, the upper and lower surfaces are preferably formed of the grooves 300, and the upper and lower surfaces are preferably formed opposite to each other. However, the present invention is not limited thereto. They may be formed to be spaced apart from each other by a predetermined distance.

At this time, the depths of the grooves 300 may be equal to or different from each other, but it is preferable that the depths of the grooves 300 do not exceed 1/3 of the length of each surface. It can not be maintained and it can be destroyed.

In this way, it is possible to ignite without using a separate ignition material by using the solid fuel 1 having a fan shape in which the fermentation alcohol has penetrated into the interior, to maintain a strong thermal power for a long time, The fermentation alcohol can be rapidly infiltrated, and it can act to help complete combustion even when burning.

Hereinafter, a method for producing solid fuel using oak according to the present invention will be described. 4 is a view showing a procedure of manufacturing a solid fuel using oak according to the first embodiment.

First, the extracted oak timber may be cut into a disk shape of 1-5 cm thick using a cutter in a direction perpendicular to the longitudinal direction to form a solid fuel base forming step (S1).

At this time, the solid fuel base 100 may be formed as an oak timber through a step of cutting the oak tree and cutting the oak tree into the solid fuel base 100 to make the wood as a log.

It is preferable to use oak as the raw material of the solid fuel base 100. This is because the material of the wood is hard and the stickiness such as the pine tree does not occur and the heat generation amount is high and the harmful ingredient It is not.

Next, the solid fuel base 100 may include a drying step (S2) of drying the solid fuel base 100 so that the moisture content is less than 10%.

In the state of the solid fuel base (100) before drying, since it has a water content of 30 50% or more on average, it can be dried naturally or in a drying device. In case of natural drying, it is affected by temperature, It may take a long time, and it is preferable to dry it in a drying apparatus, but it is not limited anymore because the water content may change.

In the case of drying in the drying apparatus, the solid fuel base 100 may be put into a drying apparatus and then dried at a temperature of 80 95 for 24 hours or more to lower the water content. This is because, when the water content of the solid fuel base 100 exceeds 10%, the water does not burn well and the alcohol does not easily penetrate.

In addition, if the temperature of the drying apparatus is set to 80 95, the drying time becomes longer if the drying temperature is lower than 80, and the wood in the drying apparatus may be burned if the drying temperature is higher than 95, This is because as the water content of the solid fuel base 100 is lowered, the amount of heat generated increases, so that a strong thermal power and a constant temperature can be maintained for a long time during the combustion.

In the drying apparatus, when the solid fuel base 100 is taken out and worked, the water content in the solid fuel base 100 increases due to the humidity in the air, so that it is preferable to perform the complete drying in the drying apparatus. It is not limited thereto.

Next, the dried solid fuel base 100 may be cut radially in a radial direction with respect to a depth 110 of the solid fuel base 100 to form a fuel chip (S3).

It is preferable that the number of the fuel chips 200 to be cut according to the diameter of the solid fuel base 100 is made different from each other and the fuel chip 200 is cut based on the water depth 110 to form the core member 140, (120).

Also, it is preferable that the cut radial surface 210 is cut naturally according to the grain, in order to facilitate the penetration of the fermentation alcohol along the grain.

Next, the cut fuel chips 200 may be placed in a settling tank before the fermentation alcohol is stored, and the settling tank may be evacuated (S4). The reason for making the vacuum state here is to increase the penetration efficiency because the penetration of the fermentation alcohol by the ring portion having a solid structure as described above is not easy.

After the inside of the settling tank is evacuated, pressure is applied to the fuel chip 200, and then the fermented alcohol is put into the settling tank in a vacuum state, and the fuel chip 200 is immersed in the fermented alcohol And injecting the fermented alcohol into the fuel body (S5). The pressure is preferably about 1.5 to 3 atm. If the pressure is too low, the penetration efficiency is low, and if the pressure is too high, it is costly to pressurize.

That is, the fermentation alcohol is put into a settling tank in a vacuum state to apply pressure once again to the fuel chip 200, thereby allowing the fermentation alcohol to permeate the interior of the fuel chip 200 to the inside in a short time will be.

In addition, the time for immersing the dried fuel chip 200 in the fermentation alcohol is not limited, and it is immersed in the sedimentation tank for 30 to 40 minutes for complete combustion in the combustion, The fermentation alcohol can be infiltrated, and the immersion time is not limited.

Meanwhile, in order to color the flame, the copper sulfate and the strobilized powder may be mixed with the fermentation alcohol, followed by the above procedure.

In another embodiment, FIG. 5 is a view illustrating a procedure of manufacturing a solid fuel using oak according to the second embodiment. (S1) and drying step (S2) are performed in the same manner as described above. Next, the solid fuel base 100 is placed in a settling tank before the fermentation alcohol is stored, and the inside of the settling tank is maintained in a vacuum state (S5) of injecting the fermentation alcohol into the solid fuel base by inserting the fermentation alcohol into the settling tank.

Since the solid fuel base 100 in the form of a disk is put into a settling tank immediately after drying and immersed in the fermentation alcohol without any moisture content, the fermentation alcohol can be more easily introduced into the interior of the solid fuel base 100 And after the fermentation alcohol has permeated, since the fermentation alcohol serves as a coating film, moisture can be prevented from being contained.

Next, the solid fuel base 100 taken out from the settling tank may be radially cut in a radial direction with respect to the water depth 110 of the solid fuel base 100 to form a fuel chip And cut into the fuel chip 200 can be performed in the same manner as in the embodiment described above.

The solid fuel 1 thus completed can be packed through a sealed packaging step S6 in which it is quickly sealed and packaged with a wrapping paper such as a foil or a synthetic resin sheet for smooth sale and transportation. Also, the packaging step should be performed as quickly as possible to prevent volatilization of the fermented alcohol impregnated on the surface and inside of the fuel chip 200.

At this time, when the solid fuel base 100 or the fuel chip 200 is in a state of being formed, the groove 300 may be formed on the flat upper surface and the lower surface of the solid fuel base 100 or the fuel chip 200, And forming a groove with a depth of 1/3 (S7).

The solid fuel produced by the present invention can be used in such a manner that at least 5 10 or more solid fuel is preferably loaded at the time of use and then fire is ignited in one of them. The use of at least 5 10 or more solid fuels at the same time is because the adjacent solid fuels 1 are burned with each other to maintain a temperature equal to or higher than the firing point so that continuous combustion can be performed.
