Description

PORTABLE BURNER USING BIOMASS NATURAL GAS}

The present invention uses biomass (herbaceous, woody plant) containing wood, which is easily available in the surrounding area, as a fuel, but the thermal decomposition products of these components and the oxygen and fuel in the air during the combustion of biomass mainly composed of cellulose and lignin. The present invention relates to a portable biomass natural gas combustor having high thermal efficiency and low fuel cost by generating natural gas formed by combining water contained therein and burning it again.

In general, fossil fuels such as electricity, gas, briquettes, and petroleum are used for the combustion device. However, due to the surge in international oil prices, interest in the development of alternative fuels has recently increased. In particular, the Kyoto Convention regulating greenhouse gas emissions due to global warming Alternative fuels are urgently needed due to fermentation.

Biomass (herbaceous, woody plants) containing wood is not only able to meet the demand from fuels that are readily available in the surroundings or traditional combustion methods (firewood stoves, firewood, incinerators), but also the only carbon absorption of greenhouse gases. Cause Its use is very limited in that it can damage the forest. In addition, in the case of alternative fuel, there was a problem that a new expensive infrastructure facility should be newly invested for supply, production, and supply of raw materials.

Thermal decomposition of cellulose ((C 6 H 10 O 5 ) n) and ligrin (C 18 H 24 O 11 ), the main components of biomass, at 400 ℃ ~ 600 ℃ generates hydrogen, carbon dioxide and carbon monoxide. H 2 O (water) and O 2 (oxygen) are artificially supplied to H 2 (hydrogen), CO (carbon monoxide) and CO 2 (carbon dioxide) generated by pyrolysis, and thus H 2 (hydrogen) and CH 4 Can produce natural gas on the principle of (methane) gas (Anil K. Rajvanshi. Chapter (No. 4) in book “Alternative Energy in Agriculture”, Vol. II, Ed.D. Yogi Goswami, CRC Press, 1986, pgs. 83-102.)

C + CO 2 = 2CO (-164.9 MJ / kg mole),

C + H 2 O = CO + H 2 (-122.6 MJ / kg mole)

CO + H 2 O = CO + H 2 (+ 42 MJ / kg mole)

C + 2H 2 = CH 4 (+ 75 MJ / kg mole)

CO 2 + H 2 = CO + H 2 O (-42.3 MJ / kg mole)

Accordingly, the present invention proposes a high-efficiency biomass combustion technology that can be used for heating or cooking in order to solve environmental problems caused by the use of fossil raw materials and to weaken the production and dissemination facilities for alternative fuels.

The upper part is provided with a combustion cylinder having a perforated inlet for introducing natural gas discharged from the throughhole to the upper side of the combustion chamber, and a transfer passage for accommodating the combustion cylinder therein and guiding the natural gas discharged from the throughhole into the inlet. The air inlet hole communicated with the outside at the bottom is perforated and the bottom plate is coupled to the bottom plate to provide convenience of maintenance at the bottom, and the bottom plate of the outer cylinder to suck the outside air through the air inlet hole and blow it to the combustion cylinder side. Characterized in that the blower is installed.

In addition, the outer cylinder is characterized in that the heat sink is further provided in the center of the blower in the center so as to protect the blower from the heat generated from the combustion cylinder between the blower and the combustion cylinder.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of a portable biomass natural gas combustion apparatus according to the present invention.

1 is a perspective view of a portable biomass natural gas combustion device according to the present invention, Figure 2 is a cross-sectional view of a portable biomass natural gas combustion device according to the present invention, Figure 3 is a principle of a portable biomass natural gas combustion device according to the present invention 4 is another embodiment of a portable biomass natural gas combustion apparatus according to the present invention.

First, the portable combustion device according to the present invention is largely composed of a combustion cylinder 10, an outer cylinder 20, and a blower 30.

Combustion cylinder 10 is installed in a spaced state inside the outer cylinder, the combustion chamber 11 for accommodating the biomass as fuel is provided, the lower portion of the intake of air required for combustion and discharge of natural gas generated during biomass combustion A through-hole 12 is drilled, and an inflow hole 13 for injecting natural gas discharged from the through-hole 12 into the combustion chamber 11 is provided above.

The outer cylinder 20 is provided with a transfer passage 40 for guiding the natural gas discharged from the through hole 12 of the combustion cylinder 10 to the inlet hole 13 in a state where the upper end thereof is closed. Communicating air inlet 21 is drilled, the bottom plate 50 is detachably coupled to provide the convenience of the bottom.

In detail, the flange 14 formed at the periphery of the combustion cylinder 10 is seated on the upper end of the outer cylinder 20 to seal the upper portion of the outer cylinder 20, and the combustion cylinder 10 is spaced apart inside the outer cylinder 20. Since it is installed in a state in which it is installed, a transfer passage 40 of natural gas is provided between the combustion cylinder 10 and the outer cylinder 20.

The blower 30 is installed on an upper surface of the bottom plate 50 of the outer cylinder 20 so as to suck the outside air through the air inlet 21 to blow the air toward the combustion cylinder 10.

Next, the outer cylinder 20 is a blower in the center to protect the blower 30 from the heat generated from the combustion cylinder 10 between the blower 30 and the combustion cylinder 10 as shown in FIG. A heat sink 60 having a perforated 61 is provided.

That is, the outside air due to the driving of the blower 30 is blown to the combustion cylinder 10 side through the blower 61, the heat generated from the combustion cylinder 10 during the biomass combustion is blocked by the heat sink 60 It is possible to prevent the blower 30 from being damaged by heat.

And the bottom plate 50 is mounted on the bottom of the battery 31 for supplying power to the blower 30, the operation unit 32 for adjusting the fire power by controlling the rotational speed of the blower 30 is the outer cylinder ( 20) It is provided at a predetermined part.

Here, the operation unit 32 controls the rotational speed of the blower 30 by varying the power applied to the blower 30. That is, by controlling the rotational speed of the blower 30 to strong, medium, or weak, the amount of air supplied during combustion is changed, so that the thermal power is also adjusted to strong, medium, or weak. The operation unit 32 can be preferably implemented as a variable resistor.

Hereinafter, with reference to Figure 3 will be described in detail the effect of the portable combustion device according to the present invention.

First, put biomass such as rice straw, rice hulls, twigs, sawdust, pellets (firewood), firewood, etc. in the combustion chamber 11 of the combustion cylinder 10, and then lights the fire blower 30, the outer cylinder 20 Air is introduced from the outside through the air inlet hole 21 and is supplied to the combustion cylinder 10 side through the air vent 61 of the heat sink 60.

Part of the air supplied to the combustion cylinder 10 is supplied to the combustion chamber 11 through the through hole 12 of the combustion cylinder 10 and another part of the air is passed through the transfer passage 40 to the combustion cylinder 10. Through the inlet hole 13 of the combustion chamber 11 is discharged to the upper side.

On the other hand, during the biomass combustion, cellulose and ligrin, which are the main components of biomass, are thermally decomposed to produce hydrogen, carbon dioxide, and carbon monoxide, and they are combined with water vapor vaporized from biomass and air to produce natural gas composed of flammable hydrogen and methane gas. Will occur.

Natural gas generated by the combustion of the biomass is discharged to the transfer passage 40 through the through-hole 12 of the combustion passage 10, the inlet hole of the combustion cylinder 10 through the air flowing through the transfer passage 40 ( 13 is introduced into the combustion chamber 11 above and combusted. Here, the inflow hole 13 of the combustion cylinder 10 is made larger than the through hole 12. For example, when the diameter of the through hole 12 is 2.5 to 3.5 mm (preferably 3 mm), the inflow hole 13 has a suitable diameter of 5 to 7 mm (preferably 6 mm).

As a result, not only the heat of combustion of biomass but also the heat of combustion of natural gas can be used, thereby improving thermal efficiency.

Here, the combustion cylinder 10 is formed such that the perforated portion 13 ′ of the inlet hole 13 is inclined outward so that natural gas may be discharged to the upper side of the combustion chamber 11. That is, as the inlet hole 13, the perforated portion 13 ′ is formed to be inclined outward, the inlet hole 13 faces the upper side of the combustion chamber 11 and the natural gas is ejected and combusted above the combustion chamber 11.

In addition, the inlet 13 is circular, as shown in Figure 4, the holes of different sizes are arranged at regular intervals, which is to maintain a wide combustion area by varying the discharge distance of the natural gas. As a result, the thermal efficiency can be further increased.

Next, the user can adjust the fire power by using the operation unit 32.

For example, when the control unit 32 is placed in a strong position so that the thermal power can be adjusted to strong, medium, or weak, the blower 30 rotates at a high speed so that a large amount of air flows into the combustion cylinder 10 and the thermal power is increased. On the contrary, if the operation unit 32 is placed at the weak position, the blower 30 rotates at a low speed, and thus the amount of air is reduced to the combustion cylinder 10, thereby lowering the thermal power.

Accordingly, the user can cook a variety of food through the thermal control.
