Embodiment
Below in conjunction with the accompanying drawings with specific embodiment to a kind of air suspended type middle high-pressure of the present invention from injection smoke-less
Ground flare burner is further described.
As shown in Figures 1 to 5, a kind of air suspended type middle high-pressure of the present invention fires from the ground flare of injection smoke-less
Burner, it includes inlet flange 1, and cylinder 2 is connected using welding manner with inlet flange 1；In cylinder 2, close to inlet flange 1
50~100mm (such as：50mm, 80mm or 100mm) place's setting speed sealer 3, adopted between speed sealer 3 and cylinder 2
Connected with the mode of being intermittently welded, 8 branch center radiant type casting shower nozzles 4, casting shower nozzle 4 and cylinder 2 are directly connected on the top of cylinder 2
Between using plug-in type welding method weld.
As shown in figure 4, the 8 branch center radiant type casting shower nozzle 4 is overall to use casting, by extending centrally out out 8
Casting shower nozzle branch 4-1.Branch's profile uses airfoil structure, reduces the caused injection resistance due to burner itself, ensures
The injection air performance of burner.
On the inside of the casting shower nozzle branch 4-1 with horizontal line counterclockwise α in a certain angle, α spans are 3 °~
8 ° (such as：3 °, 5 ° or 8 °), it make it that torch air-flow stock 1 and torch air-flow stock 2 produce low-angle mixed interference in Fig. 5, reduce
Torch gas injection flow velocity, realizes steady flame, ensures burner during oepration at full load, not de- fire.The casting shower nozzle
On the outside of branch 4-1 with horizontal line β in a certain angle clockwise, β spans be 8 °~12 ° (such as：8 °, 10 ° or 12
°), it make it that torch air-flow stock 3 and torch air-flow stock 4 are to greatest extent to circumferential scattered, raising space availability ratio in Fig. 5.
The casting shower nozzle branch 4-1 uses two STHs, and perforate ensures that perforate spacing exists along axis both sides Heterogeneous Permutation
In certain spacing range, ensure not de- fire under higher emissions pressure condition.The ratio between opening diameter d and pitch of holes L d/L are along burner
Radially gradually increase, during both can guarantee that high-pressure discharge, torch air-flow mutually ignites, while meets in burner region
Even air distribution requirement.Such as：Opening diameter is d=4.5mm, and homonymy adjacent apertures spacing L is gradually decreased to 26mm by 36mm, from
And realize Even air distribution purpose.
Described speed sealer 3 is taper, speed blanket gas outlet stream area take standpipe sectional area 0.6~
0.8, speed sealer, which prevents from pouring in down a chimney, is mixed into upstream torch pipe network.The present invention utilizes negative pressure caused by combustion gas itself injection and burning
The air being drawn in surrounding environment, so as to reach the combustion-supporting purpose of air distribution, using the structure can effectively reduce air from bottom to
Resistance is streamed during upper flowing, improves the ability for being drawn air, ensures completely burned, not over-emitting black exhaust.The present invention can be effective
The disposal ability of separate unit burner is improved, while rationally itself can discharge pressure using torch gas, reduces the steam of enterprise
Consumption, so as to reduce once input and operation cost, while safe and reliable and environmental requirement is met, economic benefit is good.
