Description
Technical field
The present invention relates to a kind of turbulent burner, particularly to one premix classification strong eddy flow minimally damaging fluid activating QI burning
Device.
Background technology
Since the nineties in last century, world energy sources shortage increases the weight of day by day with problem of environmental pollution, and burning still obtains for the mankind
One of principal mode of heat energy and power.
Industrial furnace as important thermal powerplant, it use wide, including industrial metallurgy, building, chemical industry and
The aspects such as UTILIZATION OF VESIDUAL HEAT IN.China's industrial furnace total amount is huge, and industrial furnace energy consumption is many, efficiency is on the low side, and the amount of discharging pollutants is big,
China's industrial furnace consumes fuel every year and marks coal at about 400,000,000～500,000,000 tons, and industrial furnace discharges a large amount of solid particulate matter in air simultaneously
And gas pollutant.And liquefied gas, natural gas are a kind of efficient, gaseous fuels of high-quality, cleaning, have on industrial furnace
Well prospect.Therefore, a kind of efficiency of combustion of design is high, and the gaseous fuel combustion device that pollutant emission is low, for economic benefit
And there is highly important effect in Environmental Effect Yidu.
Use the fuel gas premix burner negligible amounts of band eddy flow at present, and turbulent burner can efficient hardening combustion
Material and the mixing of air and high-temperature combustion product and unburned fuel mixed process in dirty flow field, and its returning of being formed
Stream district can be possible not only to improve flame forms and Temperature Distribution as stable incendiary source, improves efficiency of combustion, it is also possible to fall
Low stain, it is ensured that the safe operation of system.Premixed combustion can improve efficiency of combustion, the effective flame intensity strengthening locality,
If the lean premixed discharge capacity that can also reduce NOx, meanwhile, the burning that premixed combustion can also make is compared at one
Carry out in big scope.
In sum, the present invention, based on practical implementation, devises a kind of premix classification strong eddy flow low stain liquefaction
Air burner, after fuel and air sufficiently premix, forms eddy flow by master, pre-combustion grade, can form recirculating zone steady
Determine flame, expand fired downstream area simultaneously, increase heating region, thus realize the burner that usable floor area is less, it is possible to
Heating greater room scope, simultaneously also by good mixing effect, improves efficiency of combustion, reduces the discharge of pollutant.
Summary of the invention
The technical problem to be solved in the present invention is: little for existing turbulent burner combustion range, heating surface (area) (HS is little, no
The shortcomings such as stable, pollutant emission is high, it is provided that one is provided that bigger heated perimeter, stable, oligosaprobic turbulent burner, adopts
With the hydrocyclone structure of center classification give full play to pre-combustion grade for igniting and the advantage of flame stabilization, and porous blend plate energy
Enough strengthening the mixed process of fuel and air, gaseous mixture respectively enters main combustion stage again and pre-combustion grade is burnt, can be effective
Improve efficiency of combustion, reduce air pollution；The main combustion stage structure of center classifying cyclone is designed as strong cyclone structure, effectively increases
The subtended angle that big premix gas spreads in downstream, increases combustion range, and main combustion stage premix gas is lighted work by double-deck pre-combustion grade flame
With, can simultaneously be effectively solve main combustion stage ignition problem.

Device reaches pre-combustion grade downstream part through the hole on pre-combustion grade pipeline, and pre-combustion grade uses the structure of Double layer spiral flow blade, has three
Recast use, one is that the gaseous mixture of pre-combustion grade internal layer and outer layer swirl vane can be mutually mixed, and strengthens and blends.Two is always to ensure
In the case of body equivalent proportion is less than normal, the mixture equivalence that pre-combustion grade internal layer blade flows out is higher, is easier igniting and steady fire,
And the equivalent proportion of entirety is on the low side, flame temperature can be reduced, thus reduce the discharge of pollutant；Three is that pre-combustion grade uses bilayer rotation
Flow structure, inside and outside pre-combustion grade, the swirling number of two-layer swirl vane is adjustable, thereby may be ensured that the flow field control to burner downstream
More fine, reach flame structure and shape that we want.Once pre-combustion grade successful ignition, the flame of pre-combustion grade just may be used
With the gaseous mixture of main combustion stage of igniting, thus realize the burning in whole flow field.Enter the gaseous mixture of main combustion stage through swirl vane
Strong eddy flow can be formed, enter the combustor of a diameter of 4-12 times, form expansion flame, thus realize expanding the mesh of combustion flame
, enhance heating surface (area) (HS, shorten flame.The recirculating zone that strong eddy flow is formed can be relied on to stablize flame simultaneously.
The present invention compared with prior art has the advantage that as follows:
(1) have employed porous and blend plate structure, simple in construction, crushing is less, and air and combustion gas can be made to carry out fully
Mixing, overall equivalent ratio is less than normal, can reduce flame temperature, thus reduce pollutant ensureing clean-burning while
Discharge.
(2) pre-combustion grade uses the structure of Double layer spiral flow blade, has triple role, and one is pre-combustion grade internal layer and outer layer eddy flow
The gaseous mixture of blade can be mutually mixed, and strengthens and blends.Two is in the case of ensureing that overall equivalent ratio is less than normal, pre-combustion grade internal layer
The mixture equivalence of blade outflow is higher, is easier igniting and steady fire, and the equivalent proportion of pre-combustion grade entirety is on the low side, can drop
Low flame temperature, thus reduce the discharge of pollutant；Three is that pre-combustion grade uses Double layer spiral flow structure, two-layer eddy flow inside and outside pre-combustion grade
The swirling number of blade is adjustable, thereby may be ensured that the more fine of flow field control to burner downstream, reaches what we wanted
Flame structure and shape.More stablize than the pre-combustion grade device using monolayer swirl vane, be more easy to igniting and realize low row
Put.
(3) present configuration is simple, easy to assembly, is beneficial to processing, Er Qiezhu, pre-combustion grade swirling number adjustable, main pre-burning
The swirling number of level can be designed according to actual needs, can adjust the shape of flame, it is adaptable to different combustion apparatus, no
Can be only used for combustion fluid activating QI, it is also possible to burning gaseous fuel widely including natural gas, there is the widest fuel and fit
