Embodiment 1
[0031] combine figure 1 , figure 2 and image 3 , a natural gas channel circumferentially distributed burner in this embodiment is mainly composed of a burner brick body 1, a combustion air channel 2 and a natural gas channel 3, and the natural gas channel 3 includes two parts: the nozzle section 31 and the insertion section 32.
[0032] The combustion-supporting air channel 2 in this embodiment is a quadrangular hollow structure and is arranged horizontally, and is located inside the burner brick body 1 . As an outstanding improvement of the present invention, the natural gas passages 3 of the burner are evenly distributed on the four sides of the quadrilateral combustion air passage 2, which plays a role in finely splitting the natural gas fuel. It is worth noting that the natural gas passages in the present invention 3 can adopt other shape structures such as circles in the prior art. As long as there are two or more natural gas channels 3 distributed along the outer pe...
Embodiment 2
[0035] The basic structure of this embodiment is the same as that of Embodiment 1, except that the natural gas passages 3 of the burner are only distributed on two opposite sides of the quadrilateral combustion air passage 2 periphery, and the distance between two adjacent combustion air passages 2 on the same side is 60 mm, the diameter of the natural gas channel 3 is Φ20 mm; the angle α between the nozzle section 31 at the front end of the natural gas channel 3 and the central axis of the combustion air channel 2 is 20°, and the angle α between the insertion section 32 and the central axis of the combustion air channel 2 The angle β is 30°.
Embodiment 3
[0037] The basic structure of this embodiment is the same as that of Embodiment 1, except that the natural gas passages 3 of the burner are only distributed on three sides of the quadrilateral combustion air passage 2 periphery, and the distance between two adjacent combustion air passages 2 on the same side is 40 mm, the diameter of the natural gas channel 3 is Φ5 mm; the angle α between the nozzle section 31 at the front end of the natural gas channel 3 and the central axis of the combustion air channel 2 is 3°, and the angle α between the insertion section 32 and the central axis of the combustion air channel 2 β is 60°.
[0038] After the burners in Examples 2 and 3 are applied to natural gas regenerative forging furnaces, the energy-saving effect is obvious, the emission of CO in the flue gas is reduced by about 8%, and the coal consumption per ton of steel is about 75Kg standard coal / t steel.
