Embodiment
Illustrate the content of the utility model below in conjunction with specific embodiments.
As depicted in figs. 1 and 2, it is eddy flow microring array burner structure schematic diagram described in the utility model.
Please refer to Fig.1 and Fig. 2, the structure of the utility model embodiment are as follows：
Fuel conduit is gone out to fire branch pipe 3 and formed for 1, one into combustion branch pipe by the six roots of sensation into combustion distribution header 2 and 12, into combustion branch
The downstream connection of pipe 1 is uniformly distributed, under combustion distribution header 2 into combustion distribution header 2 along the circumferential direction into combustion distribution header 2
Trip connects out combustion branch pipe 3, goes out to fire branch pipe 3 and is uniformly distributed along the circumferential direction into combustion distribution header 2；Going out to fire branch pipe 3, there is provided four
The longer torch on duty of length goes out to fire the shorter main combustion torch of 4 and eight root long degree of branch pipe and goes out to fire branch pipe 5, and torch on duty goes out to fire branch pipe
4 and main combustion torch go out to fire that branch pipe 5 is alternate is evenly arranged；Torch on duty go out to fire branch pipe 4 and it is main combustion torch go out to fire branch pipe 5 open up it is more
Discharge combustion hole 6, is evenly arranged in out on the downstream semi circular surface of combustion branch pipe.
Air pipe line into empty passage 7, air cyclone 8 and steady hungry ghosts who spit fire 9 by forming；Air cyclone 8 is disposed radially two
Cyclone is enclosed, the cavity 10 that the cyclone often enclosed is made of inner and outer ring is formed with the swirl channel 11 being arranged in cavity；Eddy flow
Passage 11 can be leaf structure, beveling cellular type structure either both combining structures, and blade is employed in the present embodiment
