In order to be further described, invention further discloses following content：
Fire whirl increases fuel economy principle：
Fire whirl increase fuel economy approach be：On the one hand, swirling eddy strengthens Air Entrainment in bottom boundary,
Cause air strong near boundary layer to flow into, cause reactant quickly to mix, burnt completely, increase efficiency of combustion, subtract
The pollutant that few imperfect combustion is produced.On the other hand, swirling eddy suppresses the turbulence pulsation of flame above boundary layer, so as to press down
The generation in the large scale side whirlpool for rolling out carbon black particle can be wrapped up at flame kernel by having made, so as to reduce flue gas particle outside flame
Generation, that is, increase the time of contact of reactant, increases efficiency of combustion, reduces the pollution to environment.
Swirl flame can improve this feature of efficiency of combustion in existing rotary jet combustion chamber and rotary coal dust firing
Device has been applied.
Rotary jet combustion chamber：Atomizer is arranged in minor air cell, and fuel oil is along the injection of vortex direction, in compression process,
Air in cylinder is pushed by piston, and minor air cell is flowed into by passage, forms strong organized rotary motion, promotes vortex
Fuel distribution and mixing in room, increase efficiency of combustion.
Rotary powdered coal burner：Multistage with particular design is spoken out of turn air-supply guide frame, and coal can be made in a short time
Powder produces high temperature eddy current, accelerates the mixing of coal dust and air, with complete advantage of burning.
Fire whirl formula burner (Chinese patent CN105910102A)：Using fan blades and Mechanical Driven rotation scrim in burning
Fire whirl is produced in stove, to improve the efficiency of combustion of fuel.
Fire whirl increases flare tip life-span and flame combustion stability principle：
For jet bubble reactor, when fuel outlet speed is sufficiently large, jet flames can be elected from the mouth of pipe；If continuing to increase
The distance between flow velocity, flame root and mouth of pipe（Elect height）Also can accordingly it increase, and the now flow velocity and rapids of flame root
Stream burn rate all accordingly reduces with the increase for electing height, but because the former reduction speed is slower than the latter, therefore arrive
Up to after some critical point, the air-flow velocity of flame root can be more than turbulent combustion speed, then combustion flame can be put out.Occur
The speed of election is lower（Or elect highly higher）, then the probability of generation attaching flare tip burning is smaller, so as to increase flare tip
Service life；Blow-off velocity is higher, then the probability that generation combustion flame is put out is smaller, so as to increase jet bubble reactor flameholding
Property.
（1）Elect height
Jet bubble reactor elect height general formulae be：
（1）
In formula, h is to elect height；B is empirical；U is nozzle fuel flow rate；D is nozzle diameter.By formula（1）
As can be seen that the election height of jet bubble reactor is directly proportional to nozzle fuel flow rate.
After the effect of swirling eddy is introduced, swirling eddy can increase the stretching effect of flame base, cause flame office
Portion extinguishes, and produces and elects phenomenon, i.e., under identical muzzle velocity, and the election height for having swirling eddy to act on can be bigger.Conversely, phase
Under the conditions of same election height, fuel outlet speed can be smaller when having swirling eddy.
（2）Blow-off velocity
The calculation formula of jet flames blow-off velocity is：
（2）
Wherein, vc is jet flames blow-off velocity；SL, max are maximum laminar flame propagation velocities；ρ c, ρ ∞ are that fuel is close respectively
Degree and ambient air density；ReH is Reynolds number, and, wherein μ c are power viscosity coefficients, and H is feature
Length, represents that average fuel concentration drops to axial distance when under stoichiometric ratio.By formula（2）As can be seen that jet flames
Blow-off velocity is directly proportional to Reynolds number, and Reynolds number is directly proportional to characteristic length, then jet flames blow-off velocity and feature are long
Degree is directly proportional.
After the effect of swirling eddy is introduced, swirling eddy can suppress the turbulence pulsation of flame above boundary layer, so that
Suppress fuel above boundary layer to mix with air turbulence, reduce speed of the fuel mass percentage along central axial reduction, that is, exist
At same axial height, fuel mass percentage can be bigger when having swirling eddy effect.Conversely, in fuel concentration while dropping to
When learning below equivalent proportion, the feature height for having swirling eddy to act on can be bigger, so that the increase of jet flames blow-off velocity.
Fire whirl vortex formation mechanism：
As a kind of convection column for having strong rotation and carrying combustion phenomena, the generation of fire whirl needs three necessary factors：
（1）In the presence of a generation whirlpool；（2）In whirlpool there is a fluid to converge；（3）Horizontal surface（Such as ground, device wall）Place has
Some frictional force or drag.
Vorticity equation is：
（3）
Wherein, the generation that last three represent vorticity only on the right of equation, respectively nonconservative force, baroclinic fluid and viscous force.
Equation left side Section 2 represents that vorticity is transported because of wind, the burning that the horizontal vorticity that its place that shows to be in the wind is produced can be to leeward
Behavior is exerted one's influence.Section 1 represents that flow field medium velocity gradient can be stretched and bent to the vortex filament that oneself is present on the right of equation,
So as to which the size and Orientation of vorticity can be changed.This explanation, when the horizontal vortex filament of near wall meets with the fire plume risen, level
Vortex filament can become vertical vortex filament, and vorticity increases because of stretching, that is, form vertical concentrated vorticity.
General principle, principal character and the advantage of the present invention has been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, the original for simply illustrating the present invention described in above-described embodiment and specification
