Abstract (en)
[origin: FR2761457A1] The invention concerns a burner, in particular a single inner cone blowpipe, with flow rate premix more than 1000 l/h comprising a duct (14) supplying gas mixture having an end supplying (32) gas mixture and a single nozzle (16) for producing the flame mounted at the other end. The supply duct (14) is adapted such that, at any point of at least a transverse section thereof, the Reynolds number circulating in the supply duct (14) is less than 3000, when the burner, for example the blowpipe, operates in steady state condition at a flow rate higher than 1000 l/h. The blowpipe is useful for soldering, straightening, preheating before welding, heat forming or thermal treatment.
