The low-pressure vortex burner comprises a burner casing, wherein a burner nozzle is arranged in a mixed channel in an inner cavity of the burner casing, a vortex blade is arranged at a gas outlet end of the burner nozzle, an end part of a gas inlet side of the burner nozzle is propped against the inner wall of a gas inlet of the burner casing, a burner gland is in press-fitting on the outer end surface of the gas inlet, a gap is reserved between the burner gland and the end surface of the burner nozzle, a step is arranged on the circumferential surface of the gas inlet end of the burner nozzle, the burner casing is further provided with an air inlet, and the central line of the air inlet is perpendicular to the central line of the gas inlet. The low-pressure vortex burner is simple and reasonable in structure, targeted improvement is made aiming at problems of the conventional low-pressure vortex burner, the burner nozzle is enabled to be arranged in the inner cavity of the burner casing, the burner gland is arranged at the gas inlet of the burner casing, and a through hole in the burner gland communicates with the inner cavity of the burner nozzle.
Description
Technical field
The invention belongs to packing mechanical equipment technical field, is related to a kind of low-pressure vortex formula burner.
Background technology
The architectural feature for having flame burner nozzle is:Fuel and air were unmixed before stove is entered(High combustion rate burner makes an exception).
There is flame burner nozzle species a lot, structural shape is different, its species main according to coal gas, the length of flame, combustion intensity are determining
It is fixed.The conventional flame burner nozzle that has of heating furnace has bushing type burner, low-pressure vortex formula burner, flat seam eddy current type burner, circumferential weld eddy current type
Burner, flat flame burner, the length of flame can regulating burning nozzle, high combustion rate burners etc..
Low-pressure vortex formula burner it is relatively simple for structure, its feature is that coal gas begins to mix inside burner with air
Close, and swirl vane can be installed in air and blast tube, so mixing condition is preferably, flame is shorter.Require coal gas
Pressure it is not high, but because the swirl vane of air duct increased resistance, therefore required air pressure ratio bushing type burner is big
Some, about 1960Pa.
Conventional low-pressure vortex formula burner is positioned in burner shell by gas inlet end, causes burner nozzle and burner shell
It is unreliable to connect between body, and burner nozzle has the possibility for coming off, and there is potential safety hazard in causing the course of work.
The content of the invention
The present invention is directed to the problems referred to above, there is provided a kind of low-pressure vortex formula burner, and the nozzle structure is simple, rationally ingenious, burns
Connect reliable and stable between mouth shower nozzle and burner shell.
According to technical scheme:A kind of low-pressure vortex formula burner, it is characterised in that:It is including burner shell, described
Burner nozzle is set in burner shell inner chamber hybrid channel, and burner nozzle outlet side arranges swirl vane, burner nozzle air inlet side
End is resisted against the inwall of the gas inlet of burner shell, and burner gland press-fits on gas inlet outer face, and burner
Gap is left between gland and burner nozzle end face, the inlet end circumferential surface of burner nozzle is provided with step, and burner shell also sets
There is an air intlet, both the air intlet and gas inlet centrage is mutually perpendicular to.
As a further improvement on the present invention, the integrally formed mounting flange of the burner shell outer surface, mounting flange
End face is provided with positioning step.
As a further improvement on the present invention, the outlet side of the burner shell inner chamber hybrid channel is provided with closing in portion, institute
State mixed zone is formed between closing in portion and swirl vane.
As a further improvement on the present invention, corresponding to formation down draught slope at the lower end of air intlet on the burner shell
Mouthful.
As a further improvement on the present invention, the inlet end internal diameter of the tapered shape of the burner nozzle, and burner nozzle is big
In outlet side internal diameter.
The method have technical effect that:Product structure advantages of simple of the present invention, deposits for existing low-pressure vortex formula burner
Problem carry out specific aim improvement so that burner nozzle is placed in burner shell inner chamber, while in burner shell gas inlet
Place arranges burner gland, the through hole connection burner nozzle inner chamber on burner gland.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further described.
In Fig. 1, including burner shell 1, burner nozzle 2, burner gland 3, air intlet 4, gas inlet 5, mounting flange
6th, swirl vane 7, gap 8, mixed zone 9, closing in portion 10, positioning step 11, down draught groove 12 etc..
As shown in figure 1, the present invention is a kind of low-pressure vortex formula burner, including burner shell 1,1 inner chamber of the burner shell
In hybrid channel arrange burner nozzle 2,2 outlet side of burner nozzle arrange swirl vane 7,2 air inlet side end of burner nozzle against
In the inwall of the gas inlet 5 of burner shell 1, burner gland 3 press-fits on 5 outer face of gas inlet, and burner gland 3
Gap 8 is left between 2 end face of burner nozzle, the inlet end circumferential surface of burner nozzle 2 is provided with step, and burner shell 1 also sets
There is air intlet 4, both centrages are mutually perpendicular to the air intlet 4 with gas inlet 5.
1 outer surface of burner shell is integrally formed mounting flange 6, and the end face of mounting flange 6 is provided with positioning step 11.
The outlet side of 1 inner chamber hybrid channel of burner shell is provided with closing in portion 10, between the closing in portion 10 and swirl vane 7
Form mixed zone 9.
Corresponding to formation down draught groove 12 at the lower end of air intlet 4 on burner shell 1.
2 tapered shape of burner nozzle, and the inlet end internal diameter of burner nozzle 2 is more than outlet side internal diameter.
The course of work of the present invention is as follows:Product purpose of the present invention, operationally can be with burning-out producer coal than wide
Gas, mixed gas, coke-stove gas, it is also possible to burn natural gas.Swirl vane 7 in product of the present invention is used when natural gas is burnt,
Need only install additional at burner nozzle 2 when needing and using, coal gas amount is adapted with air capacity, and improve fuel and air
Mixing.
