Abstract
The utility model discloses a biomass boiler bocca, its bocca outer wall set up cyclone chamber and a plurality of air intake, and the air intake axis has the contained angle with the bocca radial line, and cyclone chamber's outer end face axially extends the wind channel. Cyclone chamber's wind passes through air inlet goes into the bocca and produces the whirlwind, makes the flue gas produce whirl flame, is favorable to flame to get into oxygen and flame intensive mixing before the boiler furnace, improves flame combustion temperature, simultaneously, because a wind channel is still add to the bocca, makes whirlwind flame supplementary oxygen once more before getting into boiler furnace, forms overgrate air mixed structure, and reinforcing combustion temperature reaches abundant burning purpose, reduction nitrogen oxide's production, effective control nitrogen oxide's emission.
Description
Technical field
The utility model belongs to combustion apparatus technical field, is specifically related to a kind of bocca of biomass boiler.
Background technology
At present, the burner that generally adopts fire coal or fuel oil provides heat for boiler. Along with biomass fuelExtensive use, the combustion apparatus of application biomass-burning fuel is paid much attention to. In order to improve Boiler FurnaceThorax combustion heat value, the bocca of boiler is provided with spiral-flow type air distribution structure, as patent documentationCN202056861U, discloses a kind of biomass fuel combustion device, its rotation spray nozzles comprise annular hub,Wheel rim and a plurality of spokes along the arranged tangential of wheel hub, wheel rim, spoke and wheel hub form girandoleMouth, wind forms rotary air intake by rotation spray nozzles, realizes distinguished and admirablely fully mixing with flame, makes flameColumn diameter strengthens, and heat release area change, reaches clean-burning object, but this rotation spray nozzles knotStructure complexity, processing technology difficulty, and outlet wind speed is lower, and kinetic energy deficiency, is difficult to flame to produce disturbanceAnd mixing, cause burning insufficient, easily generate a large amount of nitrogen oxide, for meet the requirement of environmental protection, also needAnother additional denitrification apparatus, increases manufacturing cost.
Utility model content
The irrational defect of flame air distribution existing in order to solve prior art biomass combustion machine, this practicalityNovelly provide a kind of bocca with binary channels eddy flow flame structure.
In order to realize above object, the technical scheme that the utility model is taked is: a kind of biomass boiler sprayNozzles, comprise bocca, and described bocca outer wall arranges cyclone chamber and several air inlets, air inlet axleLine and bocca radial line have angle, and air channel is axially extended in the outer face of described cyclone chamber.
Further, the porch of described bocca arranges the stock stop that stops solids.
Described stock stop shutter board parallel by some and that be in tilted layout forms.
Described air channel arranges cyclone blade.
Described air inlet axis and bocca axis have angle.
Compared with prior art, the utility model is due to entering of cyclone chamber and oblique setting being set at boccaAir port, the wind of cyclone chamber enters bocca by air inlet and produces whirlwind, makes flue gas produce swirl flame,Be conducive to flame and enter oxygen before boiler furnace and fully mix with flame, raising flame combustion temperature, meanwhile,Because bocca is also set up an air channel, make whirlwind flame entering before boiler furnace supplemental oxygen again, shapeBecome Secondary Air mixed structure, enhanced burning temperature, reaches abundant combustion purpose, reduces the product of nitrogen oxideRaw, effectively control the discharge of nitrogen oxide.
Brief description of the drawings
Fig. 1 is the structural representation of bocca.
Fig. 2 is the cutaway view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, the main body of bocca is bocca 1, and bocca is cylinder, the wall of bocca 1Body offers several air inlets 2. From bocca cross section, the axis of air inlet 2 and bocca 1The angle of radial line is 30～70 DEG C (preferably 50 DEG C). The outer wall of bocca 1 arranges cyclone chamber 3 around,Cyclone chamber is also cylindrical shape, between bocca 1 and cyclone chamber 3, is communicated with by air inlet 2. Due to flameMouth diameter is subject to boiler conditions restriction can not increase design, in order to ensure bocca outlet flue gas fully and airMix, the air channel 4 coaxial with bocca 1 extended in the outer face of cyclone chamber 3, and air channel diameter is less than whirlwindChamber diameter, has solved like this under less bocca diameter and has increased air capacity, uses one's intention as revealed in what one says power and increases. WindRoad 4 arranges cyclone blade 5, and the shape of cyclone blade is as fan leaf shape, and it not only works the work that supports air channelWith play guide functions simultaneously. Cyclone chamber 3 is connected with blast pipe 6 is tangent, and blast pipe is connected with air blast.
The entrance of bocca 1 arranges the shutter board 7 of 4 inclinations, and shutter board presents from top to bottom and is spaced.Shutter board is for stopping the uncombusted fuel that flue gas contains.
Certainly, in order to promote the eddy flow effect into bocca, from bocca longitudinal section, the axle of air inletThe axis of line and bocca form an angle (such as 10 degree angles).
Claims (5)
1. a biomass boiler bocca, comprises bocca, it is characterized in that: described bocca outer wallCyclone chamber and several air inlets are set, and air inlet axis and bocca radial line have angle, described whirlwindAir channel is axially extended in the outer face of chamber.
2. biomass boiler bocca according to claim 1, is characterized in that, described boccaPorch arrange and stop the stock stop of solids.
3. biomass boiler bocca according to claim 2, is characterized in that, described stock stopShutter board parallel by some and that be in tilted layout forms.
4. biomass boiler bocca according to claim 1, is characterized in that, establish in described air channelPut some cyclone blades.
5. biomass boiler bocca according to claim 1, is characterized in that, described air inletAxis and bocca axis have angle.
