For it to flame holding, combustion intensity and burner performance have wholesome effect.Till now, industrial system all makes
Use high swirling type burner, the swirling motion wherein being produced by injector (or burner) is sufficiently high, with the entrance in burner
Place produces interior recirculation region, for conventional non-premixed combustion, the effect of big recirculating zone (also referred to as vortex ring core), is
Promote the turbulent closure scheme of fuel and air, in premixing system, recirculation regions provide the stable thermal source for continuous ignition anti-
Answer thing.
Spiral combustion head 1 provides low swirl flow combustion, and its operation principle is to make use of premixed flame " propagating wave " property
Matter.The invalid burning to Nonpremixed flames, premixed flame consumes reactant, described self-sustaining reaction ripple in the form of self-sustaining reaction ripple
Formed by mixture, thermodynamic condition and turbulence intensity are propagated under the flame speed controlling.On the contrary, non-premix diffusion flame
Do not propagate, because burning occurs over just the mixed zone of fuel and oxidant stream.Low vortex combustion is referred to as using fluid machinery phenomenon
Divergent flow.As its name suggests, divergent flow is the flowing stream of extension.When it forms, strength of vortex reduces so that vortex breaker, forms stream
Move reversion and do not recycle.Therefore, the low vortex theory of combustion and high-eddy concept have basic different.Vortex ring is to protect

The size of device is less so that rotary motion remains to the inwall of combustion tube and is not penetrated into center.When flowing out burner, from
Mental and physical efforts are because rotary motion leads to stream to expand and dissipates.This divergent flow have by vortex cover around non-eddy flow core gradually under
OK.In non-eddy flow prostheses, unfavorable average axial pressure gradient is with the average axial velocity of linear reduction, this speed
Degree " gug " provides highly stable flow structure for premixing turbulent flow, and flame is freely propagated and is positioned at local velocity
Be equal to and the position contrary with flame speed at.Flame will not flash back burner, because it can not be propagated must compare burner outlet
The speed at place is fast.Blow out and be also eased, because center non-eddy flow core provides the wide region of flame natural subsidence.Prior
Be, exceed mixture inhomogeneities or slight flowing transition only cause flame location movement so that flame-out possibility
Littleization, this is a powerful self-regulating mechanism, stands transient state and the change of mixture flox condition for flame.
