Description
Invention field
The utility model relates to a kind of burner, particularly a kind of fuel burner nozzle.
Background technology
Existing fuel burner nozzle adopts the structure of sleeve pipe, the i.e. structure of sheathed combustion-supporting gas pipe outside the cartridge of internal layer, combustion-supporting gas (being generally air) mixes with fuel gas after the conveying in looped pipeline space, and spray into burner hearth with the form of swirling eddy, the two burns on burner hearth inner edge mixing limit, and in combustion-supporting gas sleeve pipe, needs to arrange spinning disk to guarantee that fuel gas mixes fully with combustion-supporting gas.In industry, natural gas or coke-stove gas are used in combustion gas more, natural gas be clean energy resource that efficiency is higher so but it needs outsourcing, use cost is high, the more important thing is, during natural gas Yong Qi peak, there will be the not good situation of supply, at this moment industrial gas can be limited use amount, civilian to guarantee, visible gas only burner adds thermal material and is subject to the restriction of industry limit gas larger.Meanwhile, existing iron and steel enterprise gaspipe network consumption is unstable, and user Dian Duo， enterprise only depends on self-produced coke-stove gas to be difficult to guarantee sufficient supply.Moreover, existing fuel burner nozzle is owing to adopting individual layer sleeve structure, air and natural gas (or coal gas) enter burner hearth with eddy flow form, because eddy flow is larger from producing resistance in nozzle, the flame that throughput is on the low side causes spraying into burner hearth can produce and waft, flame rigidity is unstable, the phenomenon that the length of flame is partially short.On the wider stove of burner hearth, use and there will be burner hearth center to have cold-zone, thereby cause burner hearth center and the burner hearth periphery temperature difference cannot meet more greatly the heating process requirement of material in stove.
Utility model content
For overcoming above-mentioned defect, the utility model provides a kind of use not to be subject to the fuel burner nozzle of industry limit gas restriction.
The utility model fuel burner nozzle comprises one-level cartridge; Described one-level cartridge exit is provided with one-level fuel nozzle ports; Also comprise secondary fuel sleeve pipe and centre wind sleeve pipe; Described secondary fuel sleeve pipe and central air hose are sheathed on outside described one-level cartridge successively; Described secondary fuel sleeve pipe tube wall is provided with secondary fuel inlet pipe, and described secondary fuel sleeve pipe discharging opening place is provided with secondary fuel spout, in described secondary fuel sleeve pipe, is provided with secondary fuel spinning disk; Described centre wind sleeve pipe tube wall is provided with centre wind inlet pipe, and described centre wind sleeve pipe exit is provided with centre wind spout, in described centre wind sleeve pipe, is provided with centre wind spinning disk.While adding thermal material, can, by regulating the pressure of the high speed combustion-supporting gas of carrying to central air hose to adjust rigidity and the length of flame of flame, control the shape of flame, better material is heated.
Particularly, also comprise wind sleeve pipe and the outlet secondary air channel adjacent with described one-level fuel nozzle ports being sheathed on outside described centre wind sleeve pipe; A described wind sleeve pipe tube wall is provided with wind inlet pipe one time, and a described wind sleeve pipe exit is provided with wind snout one time, in a described wind sleeve pipe, is provided with wind spinning disk one time.
Particularly, also comprise described one-level fuel nozzle ports and secondary fuel spout are wrapped in to interior burner block, and the ignitron of being located at described one-level fuel nozzle ports place; The exit that burner block is located at fuel mixture forms the space that isolation is heated.
Particularly, in described one-level cartridge, secondary fuel sleeve pipe, centre wind sleeve pipe, wind sleeve pipe and secondary air channel, be equipped with manograph.
Particularly, between described secondary fuel sleeve pipe and centre wind sleeve pipe, be arranged with three grades of fuel sleeve pipes.
The utility model has been realized following beneficial effect: first, by setting up secondary fuel sleeve pipe outward at one-level cartridge pipe, realized the flexible control of combustion gas distribution, can consider a kind of more cost-saving distribution scheme according to the condition of production and natural gas supply, overcome gas only burner and be subject to the high defect of industry limit gas restriction degree, made enterprise not be subject to the restriction of " natural gas is waste "; Secondly, by using multistage combustion-supporting gas pipeline and Multi-stage spiral chip technology, make burning gases larger at the pressure of nozzle, combustion flame can form stable cylindrical flame, make the intensity of flame larger, flame is longer, the parallel burner hearth that sprays into of flame, cover blank surface, RADIATION ANGLE COEFFICIENT is large, has effectively improved radiant heat transfer effect and heating quality to blank, overcome on fuel burner nozzle flame waft, the length of flame is short with the defect of flame poor rigidity, solved the problem that cold-zone appears in burner hearth center, made the heating process obtain good improvement.
