Abstract
The utility model provides a kind of combustion head used for industrial furnace, comprise jet pipe, the gas outlet of this jet pipe is connected with the nozzle of band flame spray orifice, the inner chamber of described jet pipe is provided with fire rod, be characterized in that the fuel gas inlet of described jet pipe is communicated with a fuel-air blending bin, this fuel-air blending bin comprises fuel air taking port and air air taking port; The outside of described nozzle is also connected with a boss, and this boss protrudes from described jet pipe, and the size of described boss is little compared with described nozzle, and its shape is corresponding to described nozzle.This technical scheme structure is simple, and combustion gas and air mix, sufficient combustion, and can expand burning area.
Description
Technical field
The utility model relates to a kind of combustion head, especially a kind of combustion head used for industrial furnace, belongs to " F23C uses combustion method or the equipment of fluid fuel " technical field in International Patent Classification (IPC).
Background technology
Combustion head is parts very important in industrial furnace, and affect the firepower size etc. of the Thorough combustion of combustion gas, industrial furnace, and the combustion head kind used at present is more, result of use difference is larger.Part combustion head sufficient combustion, firepower are also comparatively large, but its structure is comparatively complicated, and cost is higher, and the burning area of combustion head is by the impact of its gas outlet caliber size, and effect burning area limits to some extent; Part combustion head structure is simple, but its result of use is poor, compares waste combustion gas, and firepower is uneven simultaneously; In addition, the combustion gas of traditional combustion head and air are in gas outlet mixing, and cause fuel gas buring insufficient, the combustion gas thermal efficiency reduces, and both wastes the energy, again contaminated environment.
Summary of the invention
It is simple that the utility model object is to provide a kind of structure, and combustion gas and air mix, sufficient combustion, and the one that can expand burning area combustion head used for industrial furnace.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of combustion head used for industrial furnace, comprise jet pipe, the gas outlet of this jet pipe is connected with the nozzle of band flame spray orifice, the inner chamber of described jet pipe is provided with fire rod, the fuel gas inlet of wherein said jet pipe is communicated with a fuel-air blending bin, and this fuel-air blending bin comprises fuel air taking port and air air taking port; The outside of described nozzle is also connected with a boss, and the size of described boss is little compared with described nozzle, and its shape is corresponding to described nozzle.
Preferably, above-mentioned combustion head used for industrial furnace, capping place of wherein fuel-air blending bin is also provided with flame eye.
Preferably, above-mentioned combustion head used for industrial furnace, wherein said jet pipe is cylindrical.
Again preferably, above-mentioned combustion head used for industrial furnace, the center of wherein said boss and described nozzle on the same axis.
More preferably, above-mentioned combustion head used for industrial furnace, the sectional area size of wherein said boss is 4: 5 with the ratio of the sectional area size of described nozzle.
More more preferably, above-mentioned combustion head used for industrial furnace, the length of wherein said jet pipe is 300mm.
In addition, above-mentioned combustion head used for industrial furnace, wherein said boss is carborundum or silicon nitride or heat resisting steel goods.
Technique effect of the present utility model is mainly reflected in following two aspects:
(1) in the utility model, the fuel gas inlet of jet pipe is communicated with a fuel-air blending bin, this fuel-air blending bin comprises fuel air taking port and air air taking port, fuel air taking port and air air taking port are supplied gas simultaneously, combustion gas and air were carried out premix before entering jet pipe, in addition, the jet pipe length of traditional combustion head is at 150mm, and the length of jet pipe expands and grows to 300mm by the utility model, further ensure the stability that combustion gas and air mix and flow, make fuel gas buring abundant.
(2) in the utility model, the outside of nozzle is also connected with a boss, the sectional area size of boss is 4: 5 with the ratio of the sectional area size of nozzle, mix sufficient combustion gas and light flame under fire rod effect, flame under the effect of boss along boss edge to external diffusion, and then expand the active area of fuel gas buring, the insufficient combustion gas of burning can keep off back jet pipe and carries out second-time burning by this boss simultaneously, makes to burn more cmpletely, greatly improves efficiency of combustion.
Accompanying drawing explanation
Fig. 1: the utility model structural representation.
In figure, the implication of each Reference numeral is: 1-jet pipe, the blending bin of 2-fuel-air, 3-fuel air taking port, 4-air air taking port, 5-fire rod, 6-nozzle, 7-boss, 8-flame eye.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, is easier to make technical solutions of the utility model understand and grasp.
As shown in Figure 1, a kind of combustion head used for industrial furnace, comprise cylindrical, length is the jet pipe 1 of 300mm, and the gas outlet of jet pipe 1 is connected with the nozzle 6 of band flame spray orifice, and the inner chamber of jet pipe 1 is provided with fire rod 5, and coupling has flame eye 8, this flame eye 8 is arranged on capping place of fuel-air blending bin, and the fuel gas inlet of jet pipe 1 is communicated with a fuel-air blending bin 2, and fuel-air blending bin 2 comprises fuel air taking port 3 and air air taking port 4; The outside of nozzle 6 is also connected with a boss 7, the sectional area size of boss 7 is 4: 5 with the ratio of the sectional area size of nozzle 6, and protrudes from jet pipe 1, and its shape is corresponding to nozzle 6, on the same axis, boss 7 is carborundum or silicon nitride or heat resisting steel goods at the center of boss 7 and nozzle 6.
By describing above and can finding out, fuel air taking port and air air taking port are supplied gas simultaneously, combustion gas and air were carried out premix before entering jet pipe, in addition, the jet pipe length of traditional combustion head is at 150mm, the length of jet pipe expands and grows to 300mm by the utility model, further ensure combustion gas and air mixes, make fuel gas buring abundant, in addition, the outside of nozzle is also connected with a boss, the sectional area size of boss is 4: 5 with the ratio of the sectional area size of nozzle, mix sufficient combustion gas and under fire rod effect, light flame and flame is simultaneously monitored, flame under the effect of boss along boss edge to external diffusion, and then expand the active area of fuel gas buring, the insufficient combustion gas of burning can be kept off back jet pipe and carries out second-time burning by this boss simultaneously, make burning more cmpletely, greatly improve efficiency of combustion.
Certainly, the exemplary illustration of the above only the utility model typical apply, by the combination of same or similar technical characteristic and replacement, can form multiple concrete scheme, these schemes all drop within protection domain of the present utility model.
