Compared with prior art, the present invention have it is following prominent the utility model has the advantages that
1, it is equipped with the first diffusing opening, trunnion, the second diffusing opening and oxygen-enriched air distributor, unstripped gas is distributed by unstripped gas
Ring enters in the gap of each pipeline of oxygen-enriched air distributor, at this point, speed reduces suddenly when oxygen-enriched air reaches the first diffusing opening,
It, can be with unstripped gas mixed once by the distribution of oxygen-enriched air distributor.Mixed gas passes through trunnion and smooth belt, reaches the
It is big compared with the prior art since the effect of the second diffusing opening is mixed under the action of gas impacts again when two diffusing openings
The uniformity for improving mixing greatly is conducive to the progress burnt and reacted.
2, equipped with the inner tube protruded into for igniter, the extraction that igniter can be convenient avoids igniter and is chronically at height
Under warm environment, the service life of igniter is extended.
3, it is mounted with the support frame of support inner tube in the inner cavity of the second diffusing opening 12, can guarantee the stabilization of inner pipe end.
