The operation principle of spiral combustion first 1：Spiral combustion first 1 be all for the non-premix burner of premix it is required, because
For it has wholesome effect to flame holding, combustion intensity and burner performance.Till now, industrial system all makes
Swirling type burner high is used, wherein it is sufficiently high by the swirling motion of injector (or burner) generation, with the entrance of burner
Place produces interior recirculation region, and 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 anti-for the stable thermal source of continuous ignition
Answer thing.
Spiral combustion first 1 provides low swirl flow combustion, and its operation principle is to make use of premixed flame " propagating wave " property
Matter.To the invalid burning of Nonpremixed flames, premixed flame consumes reactant, the self-sustaining reaction ripple in the form of self-sustaining reaction ripple
It is made up of mixture, thermodynamic condition and turbulence intensity are propagated under the flame speed of control.Conversely, 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.Strength of vortex reduction when it is formed so that vortex breaker, forms stream
It is dynamic to invert and do not recycle.Therefore, the low vortex theory of combustion has basic difference with high-eddy concept.Vortex ring is to protect
Hold and continuously rekindle the basic flowing element of flame.Using cylindrical tube, a diameter of 6cm is tested, be provided with by a diameter of

The size of device is smaller so that rotary motion remains to the inwall of combustion tube and is not penetrated into center.When burner is flowed out, from
Mental and physical efforts cause stream to expand and dissipate due to rotary motion.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 with linear reduction average axial velocity, the speed
Degree " gug " provides highly stable flow structure for premixing turbulent flow, and flame is freely propagated and is positioned at local velocity
Equal to and with the opposite position of flame speed.Flame will not flash back burner, because it can not be propagated must compare burner outlet
The speed at place is fast.Blowing-out is also eased, because the non-eddy flow core in center provides the region wide of flame natural subsidence.It is prior
It is, more than the movement that mixture inhomogeneities or slight flowing transition only cause flame location so that flame-out possibility is most
Smallization, this is a powerful self-regulating mechanism, and the change of transient state and mixture flox condition is undergone for flame.

The operation principle of rod 8：Rod 8 is placed among flame, under fired state flame in tree-shaped, rod 8
Length can carry out the making of length size according to specific production technology, one is because flame height is not enough in solving industrial production,
The low problem of heated medium efficiency, not only effectively lifts flame height, simultaneously as be placed in flame burning, improves rod 8
Heat radiation effect, be conducive to thermal energy exchange；Two is to solve the too high problem of nitrogen oxides in industrial production, is contained in air
78% nitrogen, is inert gas under usual condition, only reaches 800 DEG C Celsius, and with the rising of temperature, activity is increasingly
Height, peak is reached at 1300 DEG C Celsius, and nitrogen becomes nitrogen-atoms, and the oxygen in contention air forms oxynitrides, at present
Ordinary combustion device flame is excessively concentrated, and flame local temperature is too high, even if causing in the case of 500-800 DEG C of technological requirement
Also a large amount of nitrogen oxides can be produced, the utility model of rod 8 solves flame and excessively concentrates the flame local temperature mistake for causing
Height, increases burning area, reduces the formation of nitrogen oxides.
