A new flame-stabilization technology for lean mixtures

The development of a low-pollution burner is important for saving energy an d preserving the environment. A low-pollution burner can be produced by lea n-mixture combustion and general combustion technology. The flammable limit of premixed flame is narrower than that of diffusion flame. Producing a le an mixture of fuel results in an effective combustion condition, which in t urn produces high load and low pollution. In this study, it was Found that the influx of Q(2) had an effect on extending the lean flammable limits and flame stabilization in a doubled jet burner. And the flame, consisting of small eddies, can be stabilized by the nozzle neck phenomena.
