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
There is wholesome effect to flame holding, combustion intensity and burner performance for it.Till now, industrial system all makes
With high swirling type burner, wherein the swirling motion as caused by injector (or burner) is sufficiently high, with the entrance of 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 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.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.Strength of vortex reduces 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, is provided with by a diameter of
The tangential air cyclone part of 0.7cm four small angled nozzle composition, the reactant of given fuel-air equivalent proportion are supplied
The bottom of pipe should be arrived, after turbulent flow produces plate, reaction stream interacts with the slipstream supplied by nozzle.Air sprays
The size of device is smaller 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 cause stream to expand and dissipate due to rotary motion.Under this divergent flow has the non-eddy flow core surrounded by vortex cover gradual
OK.In non-eddy flow prostheses, unfavorable average axial pressure gradient is with the average axial velocity of linear reduction, the speed
Degree " gug " provides highly stable flow structure for premixing turbulent flow, and flame is freely propagated and is positioned at local velocity
It is equal to and the opening position opposite with flame speed.Flame will not flash back burner, because it, which 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 wide region 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 subjected to for flame.

Section 7 is connect to dock.It is provided with the bottom of rod 8 and pours linkage section 12, is fixed on for pouring on premix barrel 35.
The operation principle of rod 8：Rod 8 is placed among flame, and flame is in tree-shaped under fired state, rod 8
Length can carry out the making of length size according to specific production technology, one is solve because flame height is insufficient in industrial production,
The low problem of heated medium efficiency, flame height is not only effectively lifted, is burnt simultaneously as being placed in flame, improve rod 8
Heat radiation effect, be advantageous to thermal energy exchange；Second, solving the problem that nitrogen oxides is too high in industrial production, contain in air
78% nitrogen, it is inert gas under usual condition, only reaches 800 DEG C Celsius, and with the rise of temperature, activity is increasingly
Height, peak is reached at 1300 DEG C Celsius, nitrogen becomes nitrogen-atoms, the oxygen fought in air, forms oxynitrides, at present
Ordinary combustion device flame is excessively concentrated, and flame local temperature is too high, is caused in the case of 500-800 DEG C of technological requirement
Also a large amount of nitrogen oxides can be produced, the invention of rod 8 solves caused by flame is excessively concentrated that flame local temperature is too high, increases
Big burning area, reduces the formation of nitrogen oxides.

Vertical direction forms an angle, more by an air distribution outlet 13, secondary air distribution outlet 15, air distribution outlet 16 three times air distribution, it is initial mixed
Gas is closed, is promoted to the premix inward eddy of section 17；The design of section 17 is premixed, with reference to turbulent closure scheme, jet mixing and gas dynamics
Theory, using the expansion segment 20 of different angle, advection section 21 and contraction section 18, gaseous mixture is reached optimal mixing and stir evenly effect
Fruit.At present, burner is generally used with the aeriferous combustion system of combustion gas in industrial production, and premix barrel of the present invention 35 uses
