Description
Technical field:
The utility model relates to a kind of preheated air wedge burner, the particularly a kind of industry heating of perhydro bell furnace, annealing furnace, metal smelting furnace and burner of fusing of being used for.
Background technology:
For the burner that uses in the existing industrial furnace, the central axis of burner becomes vertical direction with mounting flange, is difficult to allow the flame of burner enter along the tangential direction of industrial furnace, and the air-flow in can't the disturbance furnace chamber can not be realized the uniformity in its temperature field.Burners in prior is difficult for igniting under the cold conditions situation, perhaps flame-out easily under hot situation.Burner is the horn mouth design in the burners in prior, and the shape of flame is not controlled, and flame speed is lower, is unfavorable for flowing of the interior high temperature gas flow of industrial furnace, thereby causes the inhomogeneous of temperature.The thermal efficiency of burners in prior is lower, and the energy has been caused waste.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of preheated air wedge burner, and it is easy for installation, can reduce the energy consumption and the smog discharge temperature of industrial furnace effectively.At normal temperatures reliably the igniting, and after the combustion air preheating until 500 degrees centigrade can both be stable burning.
The utility model technical solution problem adopts following technical scheme:
Preheated air wedge burner, the main pipe that burns with tubular, be coaxially arranged with interior burner at the described main inner chamber that burns pipe, the progressive gathering of an end inner chamber of burner and communicate in described with the inner chamber of its end with described main burning pipe, the other end of interior burner is tightly connected with main end of burning pipe, and the sealing end is provided with the gas connection pipe that communicates with described interior burner inner chamber; Burn near blind end main that radial communication has air intake duct on the outer wall of pipe, offer some air admission holes on the outer wall away from the interior burner of blind end, described air inlet pipe communicates with the inner chamber of interior burner with the interlayer and the described air admission hole of interior burner by the main pipe that burns; Tilt to be connected with mounting flange at the described main outer wall that burns pipe.
Be provided with ignitor and ultraviolet detector in described main blind end end of burning pipe.
The angle that forms between the axis of described mounting flange and main burning pipe is 40-50 °.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model preheated air wedge burner is realized direct-fire or igniting indirectly, can use 500 degrees centigrade warm-up combustion-supporting air and do not influence the operate as normal of burner, even combustion system starts at normal temperatures, this burner also can successfully be put to fight and keep stable burning.
2, the interior burner inner chamber of the utility model preheated air wedge burner uniqueness draws in to design and can improve the flame speed of ejection, and flame speed can reach 80-120m/s, guarantees that the air-flow in the industrial furnace fully mixes, and realizes the temperature homogeneity in the industrial furnace.
3, use ion induction flame to detect or the detection of UV ultraviolet flame.
4, adopt flange to be connected with body of heater, be convenient to the installation and maintenance maintenance.
5, burner can directly big fire burns under cold conditions-need not the preheating burner.
6, design is applicable to high back pressure environment in the furnace chamber.
7, mounting flange and the main axis that burns pipe form 40-45 ° angle, when burner is installed on the circular industrial furnace, the flame of interior burner ejection can enter along the tangential direction of furnace chamber, the flame of burner ejection can fully stir the air-flow in the furnace chamber in making, realizes the uniformity in its temperature field.
Description of drawings:
Fig. 1 is the structural representation of the utility model burner.
Number in the figure: the 1 main pipe that burns, 2 mounting flanges, 3 bolts, 4 thermal insulation casings, 5 ignitors, 6 gas connection pipes, 7 ultraviolet detectors, 8 air intake ducts, 9 air admission holes, 10 interior burners.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment:
Embodiment: in conjunction with Fig. 1, the preheated air wedge burner of present embodiment, the main pipe 1 that burns with tubular, burner 10 in the main inner chamber that burns pipe is coaxially arranged with, one end of interior burner 10 (stretching into main that end that burns in the pipe) the progressive gathering of inner chamber, and this end end of interior burner communicates with the main inner chamber that burns pipe, and the other end of interior burner 10 is tightly connected with main end of burning pipe 1, and the sealing end is provided with the gas connection pipe 6 that communicates with interior burner 10 inner chambers; Burn near blind end main that radial communication has air intake duct 8 on the outer wall of pipe, offer some air admission holes 9 on the outer wall away from the interior burner of blind end, air inlet pipe 8 communicates with the inner chamber of interior burner with the interlayer and the air admission hole 9 of interior burner by the main pipe that burns; Tilt to be connected with mounting flange 2 at the main outer wall that burns pipe 1.Main blind end end of burning pipe 1 is provided with ignitor 5 and ultraviolet detector 7.
