Also, the third oxygen pipe is formed at an angle of 15 to 70 degrees with the fuel pipe.
Then, pure oxygen is injected through the second oxygen pipe to form a short flame, and then pure oxygen is injected sequentially through the third oxygen pipe to form a long flame.
Meanwhile, the second oxygen pipe and the third oxygen pipe simultaneously inject pure oxygen to form a long flame.
If the ignition temperature in the furnace is 700 ° C or lower, the amount of oxygen injected through the first oxygen pipe is set to 30 to 70%, and the oxygen injected through the second and third oxygen pipes is 30 to 70 %.
If the ignition temperature in the furnace is 700 ° C or higher, the amount of oxygen injected through the first oxygen pipe is 1 to 30%, the oxygen injected through the second and third oxygen pipes is 70 to 99 %.
Further, pure oxygen is injected to only one of the second and third oxygen pipes.
An oxygen burner for burning fuel with oxygen to produce a flame, comprising: a combustion block provided on a wall surface of a furnace; a fuel pipe provided at a central portion of the combustion block for injecting fuel; A first oxygen pipe for firstly injecting pure oxygen and a fourth oxygen pipe for injecting pure oxygen into the fuel pipe in the direction of the fuel pipe.

That is, as shown in FIG. 4, pure oxygen is injected preferentially through the
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
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
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
