Description

Exclusive use burner of brown gas

The present invention relates to a burner using brown gas, and more particularly, to a brown gas-only burner in which a large amount of brown gas is introduced and combusted and inserted into an incinerator or a melting furnace to improve combustion efficiency.

A burner is a device that spouts gas, liquid, or powdered fuel such as gas, oil, or fine powder at high speed. In general, a large industrial burner wastes gas or air. It is often preheated by the heat of gas. At this time, the combustion of heavy oil, kerosene, etc. is called an oil burner, and acts as a kind of sprayer that sprays oil like fog with compressed air or high pressure steam.

As such, the fuel emitted through the burner is ignited by an ignition means such as an ignition plug to generate a high temperature flame.In the industrial field, such as incineration / melting of industrial waste by using a high temperature flame. It is used throughout.

However, bunker-C oil, which is generally used in the fuel used in the burner, regulates its use due to the environmental pollution that is seriously increasing, and recommends gas fuel having less pollution than oil, but gas fuel has a high price. The situation is reluctant to use because it is expensive.

In particular, incinerators or smelters used in industrial sites have a large capacity, which inevitably leads to high fuel costs, resulting in cost competitiveness.

Therefore, the importance of alternative energy has been emphasized, and it has been invested enormously in developing alternative energy such as solar, wind, geothermal, etc., but there is no progress yet, and it is only supplementary heating means. It is no exaggeration to say that no alternative energy is available.

The use of Brown gas as a way to overcome this has been in the spotlight in recent years.

The brown gas is a gas obtained by electrolysis of water and is a mixed gas having a content ratio of hydrogen and oxygen of 2: 1. Usually, when water is electrolyzed, hydrogen is obtained at the cathode and oxygen is obtained at the anode. Brown gas is collected at once without collecting these gases separately.

Brown gas, unlike ordinary gas, has the unique property of causing an impingement phenomenon on combustion. In other words, it does not exhibit an explosion phenomenon during combustion, but rather a flame gathers inside to form a focal point and vacuum the surroundings.

That is, the brown gas flame continues to be in an implosion state. As a result, the brown gas flame forms a pinpoint flame so that the shape of the flame is long and the heat accumulation is small, but the ceramic, which is a heat-resistant material, is also used in the pinpoint portion. As it melts, it shows off a powerful firepower that can be used for flame drilling.

In addition, the flame of the Brown gas has a unique characteristic in which hydrogen and oxygen in an atomic and molecular state react. Since hydrogen atoms and oxygen atoms penetrate into the atomic nucleus of the material to be heated, the material that is heated by thermonuclear reaction by hydrogen and oxygen is heated by a flame that is much hotter than when the gas burns alone in air.

In addition, since there is no energy loss due to radiant heat because the hot wire is not emitted to the outside, it has excellent energy efficiency, and since it contains oxygen itself, no oxygen supply is needed during combustion, and only water is generated as a combustion product, thus polluting pollution. There is no.

Brown gas, which has such unique characteristics, is composed of the best burning fuel hydrogen and the supporting oxygen, so that the burner using it can get great efficiency and cost.

In order to construct a burner using the brown gas and use it in an industrial site such as incineration / melting of the waste described above, an apparatus for generating and supplying a large amount of brown gas is required, which is a brown gas generator (filed by the applicant) No. 10-2002-0006146).

However, in the related art, a brown gas burner using such a large amount of brown gas has not been developed.

The present invention is a large brown gas flows through the central passage is discharged at high speed, a part of the burner is inserted into the incinerator or the melting furnace, Brown to improve the combustion efficiency by forming a cooling unit for cooling the brown gas central passage and outlet The purpose is to provide a gas-only burner.

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

1 is a lateral cross-sectional view of a burner for exclusive use of Brown gas according to the present invention.

Referring to FIG. 1, the brown gas burner according to the present invention includes a brown gas inlet 10 through which a large amount of brown gas is introduced, a central passage 12 through which the brown gas is introduced, and the brown gas at high speed. The brown gas inlet 10, the brown gas outlet 14 formed to a diameter smaller than the diameter of the central passage 12 and the central passage 12 and the brown gas outlet 14 to cool the discharge The cooling passage 16 formed above the central passage 12 and the housing 18 surrounding the central passage 12, the brown gas outlet 14, and the cooling passage 16 are included.

At this time, the housing 18 is made of stainless metal, and the interior of the housing 18 is empty except for the central passage 12, the brown gas outlet 14, and the cooling passage 16 configured inside the housing 18. Consists of

Such a brown gas burner not only solves the pollution problem by using brown gas as a fuel of the burner, but also has excellent energy efficiency because there is no energy loss due to radiant heat because the heating wire is not emitted to the outside, and oxygen is used in itself. It has the advantage that it does not need a separate oxygen supply during combustion.

In addition, in order to configure the brown gas burner and use it in an industrial site such as incineration / melting of the waste described above, an apparatus for generating and supplying a large amount of brown gas is required, which is a brown gas generator device filed by the present applicant ( Application No. 10-2002-0006146.

Hereinafter will be described the operation of the brown gas burner as follows.

First, a large amount of brown gas is introduced through the brown gas inlet 10 provided in the brown gas dedicated burner. At this time, the brown gas inlet 10 is formed to rotate at least one or more turns, which is to allow the large amount of brown gas to be introduced while maintaining a constant speed.

That is, even when the brown gas inflow rate is suddenly increased, since the brown gas inlet 10 is formed to be rotated by one or more turns, as the brown gas passes through the brown gas inlet 10 and the friction increases, etc. The speed is somewhat reduced to maintain a constant speed and pressure.

As such, the large amount of brown gas introduced through the brown gas inlet 10 passes through the central passage 12 inside the burner and is discharged through the brown gas outlet 14.

At this time, the brown gas outlet 14 is formed with a diameter smaller than the diameter of the brown gas inlet 10 and the central passage 12 in order to discharge the brown gas at high speed.

This is because the Bernoulli theorem makes use of the property that the speed of the fluid (air, liquid) moves from a large area to a narrow area is increased, and the end of the Brown gas outlet 12 As shown in Figure 1 is formed in a streamline to prevent the vortex of the brown gas discharged.

That is, by treating the end portion of the brown gas outlet 14 in a streamlined manner as described above, the region having a relatively low pressure is removed to prevent the flame formed by the brown gas from being backfired toward the brown gas outlet 14. You can do it.

As described above, the brown gas discharged at high speed by the brown gas outlet 14 is ignited by an ignition means (not shown) such as a piezoelectric element formed on the outside of the brown gas burner to generate an ultra high temperature flame.

In the case of the present invention, when the brown gas flame is formed by the burner as described above, a part of the burner is directly inserted into various combustion chambers or in an incinerator (not shown) or a melting furnace (not shown) to incinerate or incinerate the incinerator or the furnace. Increase the melting efficiency.

Here, since the inside of the incinerator or the melting furnace maintains a high temperature, in the case of the burner for brown gas according to the present invention, the outer wall of the housing 18 of the burner may be ceramic coated, metal or nonmetal plated, for example, nickel plating or nickel / By treatment with chromium plating, it is possible not only to withstand the high temperature of the incinerator or the melting furnace, but also to prevent erosion of the burner outer housing due to the corrosive gas, thereby extending the life of the burner.

In addition, the central passage 12 and the brown gas discharge port 14 configured inside the housing 18 of the burner should be cooled, and in the present invention, the cooling passage 16 formed on the upper side of the central passage 12. Cooling the central passage 12 and the brown gas outlet 14 through.

At this time, the cooling passage 16 is formed before the Brown gas outlet 14, and water or air flowing through the cooling passage 16 is distributed and supplied to the empty space inside the housing 18 to supply the central tube. The furnace 12 and the Brown gas outlet 14 are cooled and discharged through an outlet formed in the lower portion of the housing 18.

2A and 2B are cross-sectional views A-A 'and B-B' of a particular portion of the brown gas dedicated burner shown in FIG.

That is, FIG. 2A is a longitudinal cross sectional view (A-A ') of the brown gas exclusive burner for the region where the cooling passage is formed, and FIG. ')to be.

Referring to FIG. 2A, a central passage 12 and a cooling passage 16 through which Brown gas passes are formed in the housing 18 of the burner, and the other regions are made up of empty spaces. Referring to 2b, only the brown gas outlet 14 extending from the central passage 12 is formed in the housing of the burner at this time, and the other area is made up of an empty space.

Referring to FIGS. 1 and 2A and 2B, the process of cooling the central passage 12 and the brown gas outlet 14 through the cooling passage 16 will be described below.

First, water or air is introduced through the inlet 20 formed in a part of the upper side of the housing 18. That is, the burner dedicated to brown gas according to the present invention may be water-cooled or air-cooled, and the inlet 20 is connected to the cooling furnace 16.

Accordingly, water or air introduced through the inlet 20 passes through the cooling passage 16, and the water or air passing through the cooling passage 16 is entirely dispersed in the housing 18. The inner wall of the housing 18 and the central passage 12 and the brown gas outlet 14 are cooled.

At this time, the cooling path 16 is formed before the brown gas outlet 14, which is to cool the brown gas outlet 14 more efficiently. This is because water or air is transported in a less heated state through the cooling furnace 16 until the Brown gas outlet 14, which directly cools the Brown gas outlet 14.

As such, water or air introduced through the cooling path 16 is distributed and supplied into the housing 18 to cool the inner wall of the housing 18, the central passage 12, and the brown gas outlet 14 to burner. By protecting the brown gas supply line of the burner due to the external high temperature, that is, the central passage 12, etc., the spontaneous ignition and deterioration is prevented when the brown gas is supplied to the burner, and the outlet 22 formed in the lower part of the housing 18 is provided. Is discharged through.

At this time, the outlet 22 is formed in a region corresponding to the up and down and the inlet 20 formed in the upper portion of the housing 18, which is connected to the Brown gas inlet 10 and the housing 18 It is preferable to be formed in the part to become.

According to the brown gas dedicated burner according to the present invention as described above, by using a large amount of brown gas as fuel, not only does not cause environmental pollution, but also improves combustion efficiency by inserting a part of the burner into an incinerator or a melting furnace. There is an advantage in that the burner is prevented from being overheated by forming a cooling part inside the burner to cool the part inserted into the incinerator or the melting furnace and the brown gas is discharged to form a flame.
