Description

Burner for burning system {a burner for burning system}

The present invention relates to a burner combustion apparatus that is installed on the burner side of various burners used for boiler or other heating to reduce the emission of harmful gas of the burner, and to increase the combustion efficiency.

Bunker C oil, diesel, LPG, kerosene, etc. used in the burner as a fuel emits a lot of pollutants due to unburned, and unburned gas in the gas emitted to the atmosphere during operation in the combustion device is relatively harmful. Therefore, harmful gases such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOX), which are the main causes of air pollution, are released into the atmosphere, causing serious damage to the natural environment.

Of these, carbon monoxide (CO) binds to hemoglobin in the blood and becomes CO-Hb (carbon monoxide hemoglobin), and when the concentration is 20%, headache or dizziness occurs, and if it is over 60%, it loses consciousness and it causes fatal damage. Together, HC (hydrocarbon) stimulates the mucous membranes and destroys tissue. In addition, when olefin-based aromatic hydrocarbons and NOX (nitrogen oxides), etc., are reacted by the energy of sunlight, among the CO (carbon monoxide), they produce complex compounds called oxidants, causing photochemical smog that causes visibility disorders, and chronic lung diseases. It is well known that the exhaust gas, which causes the back disease, has a harmful effect on the living environment of a person.

In other words, in order to reduce the generation of harmful gas contained in the unburned gas discharged from the burner, the oxygen supply is smoothed to increase the combustion efficiency, thereby reducing the emission of harmful gas. In addition, in order to reduce the amount of pollution with this, unburned gas reburn apparatus is installed and used.

An unburned gas generated by attaching an exhaust gas reburn apparatus registered in Korean Patent No. 189320, which is recently developed, is burned while passing through a combustion network.

When combustion of unburned gas is combusted by contact with the mesh, the contact area becomes an important factor, so that the unburned gas is brought into contact with the mesh while passing through the guide vanes and hemispherical mesh made of mesh to widen the contact area.

However, since combustion occurs while passing through the net, the unburned noxious gas passes through and the contact surface is narrow, which reduces the combustion efficiency.Induction wings are made of net and do not generate vortex, and the gas passing time is short. Meaning The combustion efficiency by recombustion of combustion gas is not shown.

Therefore, the main object of the present invention is to overlap the porous combustion tube having a plurality of gas port so as to maintain several equal intervals to be installed on both sides of the support, but the gas guide is installed on the outer periphery of the porous combustion tube to generate vortex Burner that purifies exhaust gas and improves combustion efficiency of unburned gas with catalyst by plating of catalytic metal with reburning of unburned gas, because unburned gas has a long contact path with multi-combustion pipe.

In order to achieve the above object, the present invention provides a combustion apparatus coupled to the burner side of the burner to increase the combustion efficiency,

It is installed so as to be supported on both supports by overlapping several porous combustion pipes having a plurality of gas movement holes at equal intervals so that the contact area is widened with the long moving path so that the combustion efficiency of the gas is increased. will be.

The present invention is installed so as to be supported on both sides by overlapping the porous combustion tube having a plurality of gas moving holes so as to maintain several equal intervals, the installation of several gas guides on the outer periphery of the porous combustion pipe to generate vortex in one direction Since the contact area of the porous combustion pipe is increased by increasing the momentum of the exhaust gas with a longer moving path, the combustion efficiency of the gas is increased.

The present invention also provides a catalyst for plating a burner combustor composed of a porous combustion tube installed on both sides of a support by overlapping a porous combustion tube having a plurality of gas moving holes, thereby regenerating harmful combustion gases as a catalyst along with reburning of unburned gas. It is characterized by having a burner combustion apparatus for minimizing the discharge.

Referring to the burner combustion apparatus according to the present invention as described above in detail on the basis of the accompanying drawings as follows.

Burner combustion apparatus 10 according to a preferred embodiment according to the present invention is positioned by screwing the fastener 16 to be located at the front end of the burner (E) of the burner, as shown in Figure 1 and 2, The burner combustion apparatus 10 is easily heated by unburned gas, and the gas moving holes 12 are drilled at equal intervals so that the gas can be easily moved from inside to outside and from outside to inside, so that the unburned gas may be smooth. The movement is made.

Since the gas moving holes 12 are installed so that the plurality of perforated combustion pipes 11 are opened at equal intervals so that several equal intervals are maintained so as to be supported by the support 13 on both sides, the unburned gas heats the porous combustion pipe 11. While moving through the gas movement path 15 between the porous combustion pipes 11 installed so as to maintain a uniform spacing of a large surface area, the contact with the porous combustion pipes 11 is made, and the gas movement holes 12 are rapidly moved. Some resistance is generated, resulting in an irregular flow.

Irregular and rapid flow of unburned gas causes contact with the surface of each of the multi-combustion pipes 11 by the movement of the long gas moving path 15, and the irregular flow increases the contact rate with the multi-combustion pipe 11. The increase in fluidity of the unburned gas increases the combustion efficiency of the gas because the contact area of the unburned gas becomes wider while maintaining the high temperature in the porous combustion pipe 11.

Here, the support 13 installed on both sides of the burner combustion apparatus 10 is installed so that several porous combustion pipes 11 overlap each other, so that the appropriate space is maintained between the combustion pipes 11, respectively, so that the gas flow path (15) is secured, but the parts that are in contact with each other by welding or the like can also be installed by assembling, but fully bonded state is preferable.

As another embodiment according to the present invention, the burner combustion apparatus 20 is positioned by screwing to the fastener 16 so as to be located at the crater E side of the burner as shown in FIGS. 3 and 4. As such, the burner combustor 20 is easily heated by the exhaust gas, and the gas moving holes 12 are drilled at a plurality of equal intervals so as to easily move from inside to outside from outside to inside. Unburned gas is smoothly moved to the inside of 20.

At this time, several gas guides 24 are inclined at the outer periphery of the Nagong combustion pipe 21 so as to effectively move the unburned gas, so that vortices are generated in one direction. Along with the long gas moving path 25, the momentum of the unburned gas is increased to increase the contact area of the porous combustion pipe 21, thereby increasing the combustion efficiency of the gas.

In other words, the gas guide 24 is a state in which the unburned gas is rotated through the gas moving path 25 in the porous combustion tube 21 while being in contact with the surface of the porous combustion tube 21 by centrifugal force. Significantly longer, so that the temperature of the combustion device 20 is further increased, the unburned gas is effectively burned.

The gas guide 24 should be gentle inclined so as to have less resistance when discharging unburned gas, and may be attached to the porous combustion tube 21 by welding. Although not shown, the porous combustion tube 21 may be used. Forming a portion of the incision by bending it does not significantly affect the operation of the combustion device (20).

And the gas guide 24 has a spacer function to maintain the interval of the multi-combustion pipe 21 is installed at equal intervals by overlapping several, and with this, a plurality of gas moving holes 12 are drilled at equal intervals. It is preferable that the performance element pipe 21 is installed so as to be supported by both support members 13 so as to be overlapped so that several equal intervals are maintained, and manufactured in a fixed state by welding or the like.

This prevents abrasion and breakage, reduces noise, and heats the unburned gas evenly in the high temperature state, while heating the porous combustion tube 21 evenly, while providing a gas guide between the porous combustion tubes 21 having a wide surface area. 24 is guided to the porous combustion tube 21 while moving through the gas movement path 25 as described above, and a slight resistance occurs in the gas movement port 12 due to the rapid movement, thereby causing an irregular flow.

Irregular and rapid flow of unburned gas is guided to the gas guide 24 to cause contact with the gas guide 24 and the surface of each of the multi-combustion pipe 21 by the movement of the long gas flow path (25). Irregular flow increases the contact rate to the porous combustion tube 21 and increase in fluidity of the unburned gas enables maintaining the high temperature state in the porous combustion tube 21 while increasing the contact area of the unburned gas. It will increase the combustion efficiency of the gas.

Here, the support 13 installed on both sides of the burner combustion apparatus 20 as described above is installed so that several porous combustion pipes 21 overlap each other, so that the appropriate spacing is maintained between the porous combustion pipes 21, respectively. It is possible to secure the gas movement path 25, but it is preferable to join the parts which are in contact with each other by welding or the like, even though they can be installed but there is no flow.

Figure 5 shows the installation state of the porous combustion tube 21, the present invention as described above is a wide contact with the unburned gas in a high temperature state at the time of discharge of the unburned gas is also efficient contact with the plated catalyst metal Since the catalytic action is also effective, the nitrogen oxide contained in the unburned gas in addition to the sulfur oxide is related, so to purify it, the purification device is formed by plating a catalyst containing aluminum oxide-platinum-palladium (or rhodium) By passing through the inside of (10) and (20), oxidation and reduction are carried out to convert harmful gases into harmless gases for combustion and purification of unburned gas.

According to the present invention, since a gas guide is installed at the outer periphery of the porous combustion pipe to generate vortices, the combustion area of the unburned gas increases along with a long moving path, thereby increasing the recombustion efficiency of the unburned gas. Since the unburned gas is purified by the catalyst by plating of the catalytic metal, there is an effect of double purification to reduce environmental pollution.
