Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment upper air inlet burner.
Fig. 2 is the overlooking structure diagram of the utility model embodiment upper air inlet burner.
Specific embodiment
As follows in conjunction with attached drawing, application scheme is further described:
Embodiment:
Referring to attached drawing 1-2, a kind of upper air inlet burner, the burner main body 1 including being provided with gas seat 2 is arranged on the gas seat 2
There are multiple nozzles, between the nozzle and the inlet end of burner main body 1 there is spacing to form mixed gas with preliminary mixing air,
Outer ring ejector pipe 12, the centre porosity that the burner main body 1 is provided with center ejector pipe 11, is set to 11 two sides of center ejector pipe
14 and outer ring stomata 13, the outer ring ejector pipe 12 connects outer ring stomata 13, and the center ejector pipe 11 connects centre porosity
14, it is additionally provided with tortuous mixed air cavity 17 between the outer ring ejector pipe 12 and outer ring stomata 13, is drawn by the way that two outer rings are arranged
Pipe 12 is penetrated to improve the soakage of fuel gas supply and primary air and then improve combustion efficiency and efficiency of combustion.
Further, it is provided with the first air inlet 21 and the second air inlet 22 on the gas seat 2, the nozzle includes center
Nozzle 23 and outer ring nozzle 24, first air inlet 21 connect central nozzle 23, and second air inlet 22 connects outer ring spray
Mouth 24.
Further, the outer ring nozzle 24 is corresponding with outer ring ejector pipe 12, the central nozzle 23 and center ejector pipe
11 is corresponding.
Further, the central nozzle 23 is different with the level height of outer ring nozzle 24, the corresponding center injection
The inlet end of pipe 11 and the inlet end of outer ring ejector pipe 12 be not in same level more to fill in different level upper air
Divide the air using solid space, improves air imbibed quantity.
Further, the outer ring ejector pipe 12 and mixed air cavity 17 form J-type and move road to form tortuous mixed gas
Diameter extends incorporation time, and then improves mixed effect.
Further, it is provided with distributor mounting base 15 in the burner main body 1, is arranged in the distributor mounting base 15
There is surrounding edge to install distributor, multiple arcs recess portion 16 is provided on the surrounding edge to form limit, so that distributor installation is more
Adding securely prevents from shifting.
It is that above-mentioned preferred embodiment should be regarded as application scheme embodiment for example, all with application scheme thunder
Same, approximate or technology deduction, replacement, improvement for making based on this etc., are regarded as the protection scope of this patent.
