Embodiment 1
[0023] Such as figure 1 As shown, this embodiment provides a flat wall-attached flame burner heating two-step furnace type double-sided radial spiral coil heating furnace. It is a combined section with a rectangular lower part of a positive trapezoid, including steel structure, flat wall-attached flame burner 1-1, spiral coil 2, pipe frame 3, inner ring radiation wall 4-1, outer ring radiation wall 4-2, Inner ring furnace wall panel 5-1, outer ring furnace wall panel 5-2, flue exhaust duct 6.
[0024] The outer ring furnace wall plate 5-2 is arranged inside the steel structure of the heating furnace. The inner ring radiation wall 4-1 is attached to the outer side of the inner ring furnace wall panel 5-1, the outer ring radiation wall 4-2 is attached to the inner side of the outer ring furnace wall panel 5-2, and the spiral coil tube 2 is formed by the tube The frame 3 is fixedly arranged between the inner ring radiation wall 4-1 and the outer ring radiation wall 4-2; 1 heat...
Embodiment 2
[0028] Such as figure 2 As shown, this embodiment also provides a combination of a flat wall-attached flame burner and a radiant wall-type flameless burner for heating with a double-sided furnace wall spiral coil heating furnace. The cross-section is rectangular, including flat wall-attached flame burner 1-1, radiant wall-type flameless burner 1-2, spiral coil 2, pipe frame 3, inner ring radiant wall 4-1, outer ring radiant wall 4 -2. Inner ring furnace wall panel 5-1, outer ring furnace wall panel 5-2, flue exhaust duct 6.
[0029] The inner ring radiation wall 4-1 is attached to the outer side of the inner ring furnace wall panel 5-1, the outer ring radiation wall 4-2 is attached to the inner side of the outer ring furnace wall panel 5-2, and the spiral coil 2. The pipe frame 3 is fixed between the inner ring radiation wall 4-1 and the outer ring radiation wall 4-2; when the height of the spiral coil furnace tube is above 5-6m, except for the flat wall-attached flame burne...
Embodiment 3
[0033] Such as image 3 As shown, this embodiment also provides a radiant wall-type flameless burner heating double-sided radiant spiral coil heating furnace. Type flameless burner 1-2, spiral coil 2, pipe frame 3, outer ring radiation wall 4-1, inner ring radiation wall 4-2, inner ring furnace wall 5-1, outer ring furnace wall 5- 2. Exhaust flue 6.
[0034] The inner ring radiation wall 4-1 is attached to the outer side of the inner ring furnace wall panel 5-1, the outer ring radiation wall 4-2 is attached to the inner side of the outer ring furnace wall panel 5-2, and the spiral coil 2 is fixed by the pipe frame 3 and placed between the inner ring radiation wall 4-1 and the outer ring radiation wall 4-2; the inner ring radiation wall 4-1 and the outer ring radiation wall 4-2 are flameless The burner 1-2 heats up the radiation wall of the inner and outer rings to a high temperature, and heats the medium to be heated by the heating furnace through the spiral coil 2 that is rad...
