FIG.

The present invention relates to an oxygen burner. As shown in FIG. 2 and FIG. 3, the oxygen burner includes a combustion block 100 installed on a wall surface of a furnace, a fuel pipe 100 disposed in a central portion of the combustion block 100, A first oxygen pipe 120 provided to surround the fuel pipe 110 and the fuel pipe 110 so as to inject pure oxygen first and a second oxygen pipe 120 provided at upper and lower portions of the outer side of the first oxygen pipe 120, A second oxygen pipe 130 for injecting oxygen, and a third oxygen pipe 140 provided at upper and lower portions of the second oxygen pipe 130 for injecting second pure oxygen.

The fuel pipe 110 and the first oxygen pipe 120 pass through the combustion block 100 so that the fuel pipe 110 is connected to the first oxygen pipe 120 through pure oxygen And the flame is generated in the furnace by spraying the gas into the furnace. Unlike the second and third oxygen pipes 130 and 140, pure oxygen is continuously injected to generate a flame.

As shown in FIGS. 2 and 3, the second oxygen pipe 130 and the third oxygen pipe 140 may be formed only on the upper portion and the lower portion of the first oxygen pipe 120, But may be formed at predetermined intervals in the circumferential direction on the outside of the first oxygen pipe 120 as needed.

Here, the second oxygen pipe 130 and the third oxygen pipe 140 inject pure oxygen in the direction of the fuel pipe 110 to prevent the temperature from rising during the auto-ignition and to increase the length of the flame The inside of the furnace can be stably heated.

More specifically, the second oxygen pipe 130 is formed at an angle of 5 to 60 ° with the fuel pipe 110, and the third oxygen pipe is formed at an angle of 15 to 70 ° with the fuel pipe, The oxygen is sprayed toward the flame formed on the entire fuel pipe 110 in the second and third oxygen pipes 130 and 140 to prevent the flame from spreading in the width direction and to form the long length, I can do it.

At this time, the second oxygen pipe 130 and the third oxygen pipe 140 inject pure oxygen. When oxygen is injected, oxygen is injected sequentially over time to form a longer length of the flame do.

That is, as shown in FIG. 4, pure oxygen is injected preferentially through the second oxygen pipe 130 so that the flame is prevented from diffusing by colliding with the flame first, and then the third oxygen pipe 140 Pure oxygen is injected to make a second collision with the flame to form a longer flame.

Thus, the entire length of the furnace can be stably heated by increasing the length of the flame, and the heat generated at the time of auto-ignition can be prevented from exceeding a predetermined value to suppress generation of soot or NOx gas by combustion Thereby reducing environmental pollution.

The second oxygen pipe 130 and the third oxygen pipe 140 may sequentially inject pure oxygen with a time difference, and the second oxygen pipe 130 and the third oxygen pipe 140 may be sequentially injected, At the same time, the length of the flame can be controlled by injecting pure oxygen.

Also, depending on the size of the furnace to be used, the length of the flame may be long or the length of the flame may need to be kept short. The length of the flame can be increased by using both the second and third oxygen pipes 130 and 140 The length of the flame may be shortened by using only the second oxygen pipe 130 as shown in FIG. 5, or the length of the flame may be shortened by using only the third oxygen pipe 140 as shown in FIG. 6, The length of the second oxygen pipe 130 and the length of the second oxygen pipe 130 may be shorter than the length of the flame using only the second oxygen pipe 130.

When the length of the flame and the temperature of the flame are controlled, the amount of fuel may be controlled, but the amount of oxygen injected from the first oxygen pipe 120 and the amount of oxygen injected from the second and third oxygen pipes 130, So that the temperature and length of the flame can be controlled.

If the ignition temperature in the furnace is 700 ° C or less, the amount of oxygen injected through the first oxygen pipe 120 is 30 to 70%, the amount of oxygen injected through the second and third oxygen pipes 130 and 140 is 30 To 70%, so that the temperature in the furnace can be stably maintained.

If the ignition temperature in the furnace is 700 ° C or higher, the amount of oxygen injected through the first oxygen pipe 120 is set to 1 to 30%, and oxygen injected through the second and third oxygen pipes 130 and 140 is set to 70 To 99% so that the temperature inside the furnace does not become too high and the temperature is stably maintained.

Therefore, when only the air pipe 3 is formed outside the fuel pipe as in the prior art shown in FIG. 1, the auto-ignition temperature is increased as shown in FIG. 8 to increase the amount of the rust gas generated, When used, the auto-ignition temperature is lower than the conventional one, so that the generation amount of the rust gas is reduced, thereby preventing environmental pollution.

7, a combustion block 100 installed on a wall surface of a furnace, a fuel pipe 110 provided at a central portion of the combustion block 100 to inject fuel, A first oxygen pipe 120 for injecting pure oxygen to surround the pipe and a fourth oxygen pipe 150 provided outside the first oxygen pipe 120 for injecting pure oxygen in the fuel pipe direction And a branch pipe 155 is further formed in the center of the fourth oxygen pipe 150 in the fuel pipe direction.

Thus, air is injected into the fourth oxygen pipe 150, and pure oxygen is simultaneously injected into the fourth oxygen pipe 150 and the branch pipe 155 to form a long flame.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the scope of the present invention is not limited to the disclosed embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
