Summary of the invention
Harsh for the specification requirement that solves existing startup burner existence, as easily to be burned technical problem the invention provides a kind of non-premixed startup burner.
Technical solution of the present invention is:
A kind of non-premixed startup burner, described burner head is provided with head spray part 2, its special character is: described head spray part 2 comprises end plates, oxidant channel 4, incendiary agent passage 5, water-cooling sandwich, described end plates respectively with oxidant channel 4, incendiary agent passage 5, water-cooling sandwich 3 welded seals; The end plates 12 of described head spray part are provided with flame-thrower nozzle, described flame-thrower nozzle comprises eight oxidize nozzles 7 and an incendiary agent nozzle 6, described oxidize nozzle 7 is connected with oxidant channel 4, described incendiary agent nozzle 6 is positioned at the end plates center and is connected with incendiary agent passage 5, is provided with atomizer 9 between described incendiary agent nozzle 6 and incendiary agent passage 5; Described a plurality of oxidize nozzle 7 evenly is arranged on around incendiary agent nozzle 6 and the angle between oxidize nozzle 7 axis and head spray part end plates 12 is 34 degree; Described water-cooling sandwich 3 is logical with the outer loop water.
The present invention has advantages of:
1, utilize incendiary agent independence atomizing type to realize that in oxidant or non-oxidation agent situation, incendiary agent all can spray by atomizing type, in case the oxidant ejection is arranged, two media can mix and realize burning.So greatly simplify the aspect that system controls incendiary agent oxidant stress and sequential have been controlled requirement, greatly widened the adjustable range of oxidant incendiary agent mixing ratio, can cutoff, avoided the cost that repeats to drive due to system's reason medium supply fluctuation.
2, the present invention is by mixing incendiary agent and oxidant after first spray burning agent again, the problem of easy tempering when having solved original premix burner nozzle at all and driving and cut-off.
3, head spray part of the present invention is the integral type structure, and namely oxidize nozzle and incendiary agent nozzle are arranged on same part, and the quality of flame just can guarantee by processing, has avoided so original product repeatedly to load and unload and has caused the problem that flame quality descends.
4, incendiary agent of the present invention and oxidant be separately by the ejection of self nozzle, then passes through certain apart from blending, through just beginning to produce flame after certain blending distance.By cold fluid and mixture, flame and the head spray part head of high temperature are fully isolated like this, avoided the destruction of thermal-flame to head spray part.And the expansion process after cold fluid high-speed ejection head spray part is again a process of cooling in fact, has so just realized the cooling itself of medium to head spray part head itself.So having overcome original burner thermal-flame, the present invention directly is attached to the defective that the burning of head spray part wall causes head spray part easily to destroy.
5, be provided with water-cooling sandwich in head spray part, in addition cooling to the burner outer wall by the turnover of cooling water.Simultaneously, water-cooling sandwich of the present invention only needs to resist the radiant heat from gasification furnace, and needn't consider thermal-flame to the destruction of head, so simple in structure.
