Abstract
The utility model provides a combustible gas combustion device, which includes a nozzle, a flame stabilizing tube, and an ignition-flame detection electrode. An orifice of the nozzle extends into the interior of the flame stabilizing tube, a multi-orifice plate is arranged in a position adjacent to the top end inside the flame stabilizing tube, a plurality of gas inlets are formed on a side wall of the flame stabilizing tube, and the ignition-flame detection electrode is used for igniting the combustible mixed gas in the flame stabilizing tube through electric discharge, and detecting the combustion flame. Through the reasonable structural design, the combustion device dispenses with a combustion air conveying and supplying system necessary for present flame combustion, not only lowers equipment cost but also saves the device installation space, and further greatly reduces the difficulties in manufacture, installation, operation and maintenance of the combustion device.
Description
Technical field
The utility model relates to a kind of gas fuel burning device.
Background technology
In some industrial processes, tend to produce some poisonous combustible waste gas.When these exhaust gas discharging amounts are bigger, the value of recycling is just arranged.When these exhaust gas discharging amounts were smaller, the cost of recycling will be higher than the value that utilization again brings far away, and the waste gas of this moment is just directly discharged.But the flammable composition in the waste gas often all contains severe toxicity, directly discharges not only contaminated environment, and can influence the safety of production.Just need carry out ignition to these waste gas this moment handles.Contain the influence of the toxic emission of fuel gas to environment in order to reduce as much as possible, the exhaust gas discharging mouth is general all in tens meters high high-altitudes, and this has just increased the difficulty of these waste gas being carried out the ignition harmless treatment.
At present, the device that is widely used in combustible exhaust gas discharging igniting is a kind of fuel gas igniter burner.The complex structure of fuel gas igniter burner needs special combustion air supply again simultaneously, and its auxiliary device is huge, and weight is bigger, causes difficulty is installed, and Operation and Maintenance is difficult for waiting not enough.
The utility model content
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, provide a kind of do not need the specialize in supply combustion air, simple in structure, the flame stabilization performance is good, the flame adjusting range is wide, flue-gas temperature is high, equipment is installed gas fuel burning device simple, convenient operating maintenance.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:
A kind of gas fuel burning device, it comprises nozzle, steady flame tube, reaches igniting-flame detection electrode, the spout of described nozzle stretches to the inside of described steady flame tube, position near the top in the described steady flame tube is equiped with a porous plate, offer a plurality of air admission holes on the sidewall of steady flame tube, described igniting-flame detection electrode is used for the combustion mixture body in the described steady flame tube of discharge igniting, and combustion flame is detected.
In the such scheme, the inwall of the outer wall of nozzle and steady flame tube is by being threaded, and the spout that is used to regulate nozzle stretches to the degree of depth of steady flame tube.
The beneficial effect of this gas fuel burning device is:
1, passes through reasonable structural design, omitted the supply system of the prerequisite combustion air conveying of flame combustion in the past, not only reduce equipment cost, and saved the Unit Installation space, thereby greatly reduced the difficulty that it is made, installs, operates, safeguards.
2, self flameholding, the fired state adjusting range is extensive.
3, ignition operation is in stable condition, and it is little influenced by external environment.
Description of drawings
Fig. 1 is the structural representation of gas fuel burning device of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is that the A-A of Fig. 2 is to view.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of gas fuel burning device that it provides for the utility model embodiment, it comprises nozzle 1, steady flame tube 2, reaches igniting-flame detection electrode 3.The spout 4 of nozzle 1 stretches to the inside of steady flame tube 2, and the inwall of the outer wall of nozzle 1 and steady flame tube 2 is by being threaded, and the spout that can regulate nozzle 1 stretches to the degree of depth of steady flame tube 2, is preferably the middle part that stretches to steady flame tube 2.Position near the top in the steady flame tube 2 is equiped with a porous plate 5, makes that flame can smooth combustion in steady flame tube 2.Steady flame tube 2 offers a plurality of air admission holes 6 near on the sidewall of bottom, is used for air and enters.Igniting-flame detection electrode is used for the combustion mixture body in the steady flame tube 2 of discharge igniting, and combustion flame is detected.
The size of steady flame tube 2 port combustion flames can realize by the fuel gas pressure that adjusting enters nozzle 1.The temperature of the temperature of steady flame tube 2 termination flue gases and steady flame tube 2 itself can stretch into the degree of depth of steady flame tube 2 inside by the spout 4 of regulating nozzle 1 and adjust during no flame heat.
Be understandable that, can utilize a flame controller control igniting-flame detection electrode 3, realize remote-controlled operation.
The operation principle of this gas fuel burning device is: fuel gas enters in the steady flame tube 2 by the spout of nozzle 1, and and the air of steady flame tube 2 inside mix, mist is lighted in 3 discharges of igniting-flame detection electrode then, flame is in steady flame tube 2 internal combustion, and to the top jet of steady flame tube 2.When the flue gas of combustion flame and formation thereof sprays steady flame tube 2, cause the pressure at nozzle 1 spout 4 places in the steady flame tube 2 to reduce, air in the environment is drawn into its inside from the air admission hole 6 of steady flame tube 2, and fuel gas constantly from nozzle 1 ejection, has just formed the retention flame continuously in a steady stream.The temperature of steady flame tube 2 improves, and also makes the temperature of its top flue gas be higher than 1000 ℃ simultaneously, and partial combustion flame is pulled to the termination smooth combustion of steady flame tube 2.If have combustible exhaust gas in the surrounding environment at this moment steady flame tube 2 tops, the flame or the high-temperature flue gas of steady flame tube 2 ejections just can be lighted these fuel gas, reach the purpose of exhaust-gas treatment.The steady flame tube 2 that is burnt red has well guaranteed the environment temperature of flame region, thereby has guaranteed flame burning stability.Stability and reliability with its flame ignition external environment combustible exhaust gas have been guaranteed in the smooth combustion of flame in the steady flame tube 2.Fuel gas can be coke-stove gas, mixed gas, town gas, also can use natural gas, liquefied petroleum gas etc.
Be understandable that this gas fuel burning device also can be used for the small-power heating in the industrial production, direct trustworthy flame tube 2 can be widely used in fields such as iron and steel, food, chemical industry near being heated equipment or parts just can be realized during use.For example, in the process that some iron and steel enterprises produce, limit portion crackle appears easily in the expansion process of thicker band coil of strip.By this gas fuel burning device the limit portion to these coil of strips is carried out small-power heating, can reduce the generation of this limit portion crackle.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
