Abstract
The utility model provides a kind of spiral casing type coal fines burner, comprises air intake and connects pipeline section, to be connected the wind coal dust air-out pipeline section that helically formula that pipeline section connects inwardly coils with this air intake, and it is vertical that air outlet and the air intake of this wind coal dust air-out pipeline section are connected pipeline section.Force the mode of High Rotation Speed to send into burner hearth by just coal dust and wind by spiral case passage, thus meet the requirement of combustion path length in little space, substantially increase the burn-off rate of coal dust.Meanwhile, because of abundant mixing and the High Rotation Speed of wind and coal dust, achieve good atomization, be conducive to burning.In addition, solid particle is than wind weight, and during rotation, majority concentrates on outer, and local improves the concentration of coal dust, is conducive to ignition.
Description
Technical field
The utility model belongs to coal powder burning technology field, is specifically related to a kind of spiral casing type coal fines burner.
Background technology
The necessary condition of coal dust efficient burning: 1. sufficiently long combustion path; 2. enough good atomization; 3. enough ignition concentration; 4. sufficiently high fire box temperature; 5. enough thin coal powder size; 6. sufficiently high coal dust calorific value.
Wherein combustion path, atomization and ignition concentration are closely-related with burner.
The limited length of existing small boiler, is difficult to the requirement meeting combustion path length.
Utility model content
The purpose of this utility model overcomes existing small boiler (burner) limited length, is difficult to the defect of the requirement of the length meeting burnup path, to realize the efficient burning of coal dust.
For achieving the above object, the utility model provides a kind of spiral casing type coal fines burner, its special character is, comprise air intake to connect pipeline section, to be connected the wind coal dust air-out pipeline section that helically formula that pipeline section connects inwardly coils with this air intake, it is vertical that air outlet and the air intake of this wind coal dust air-out pipeline section are connected pipeline section.
The center of wind coal dust air-out pipeline section is also provided with the secondary wind inleting tube of one and its coiling central coaxial.
Coaxial and its external diameter is less than the caliber of the air outlet of this wind coal dust air-out pipeline section to secondary wind inleting tube with the air outlet of wind coal dust air-out pipeline section.
The top of wind coal dust air-out pipeline section is provided with suspension ring.
The utility model has the advantages that: spiral casing type coal fines burner forces the mode of High Rotation Speed to send into burner hearth by spiral case passage coal dust and wind, thus meet the requirement of combustion path length in little space, substantially increases the burn-off rate of coal dust.Meanwhile, because of abundant mixing and the High Rotation Speed of wind and coal dust, achieve good atomization, be conducive to burning.In addition, solid particle is than wind weight, and during rotation, majority concentrates on outer, and local improves the concentration of coal dust, is conducive to ignition.

Detailed description of the invention
In order to overcome existing small boiler (burner) limited length, be difficult to the defect of the requirement of the length meeting burnup path, the present embodiment provides the spiral casing type coal fines burner being applicable to Small Combustion stove shown in a kind of Fig. 1, comprise and (by distinguished and admirable, coal dust being sent into for air intake coal dust, therefore distinguished and admirablely a large amount of coal dust is included, therefore be called wind coal dust) air intake connect pipeline section 1, be connected helically formula that pipeline section 1 connects inwardly to coil (form scroll casing type with this air intake, therefore called after spiral casing type coal fines burner) wind coal dust air-out pipeline section 2, the air outlet of this wind coal dust air-out pipeline section 2 is connected pipeline section 1 with air intake vertical, as shown in Figure 2.
In order to ensure enough intakes, this enforcement is also provided with the secondary wind inleting tube 3 of one and its coiling central coaxial in the center of wind coal dust air-out pipeline section 2, thus, supplementing intake is realized by this secondary wind inleting tube 3, the good atomizing effect of the wind coal dust entered in combustion furnace can be realized very well, also be conducive to ignition and the burning of coal dust, be conducive to Thorough combustion and the sulfuration of coal dust, be beneficial to environmental protection.
Can be cleaned by Fig. 2 and seem, coaxial and its external diameter is less than the caliber of the air outlet of this wind coal dust air-out pipeline section 2 to secondary wind inleting tube 3 with the air outlet of wind coal dust air-out pipeline section 2.Through wind coal dust air-out pipeline section 2 discharge distinguished and admirable be the stove whirlwind after break-in, and to blow in combustion furnace.
In addition, can by setting up valve to realize the regulation and control to air quantity on secondary wind inleting tube 3, to realize the control mode of energy-conserving and environment-protective as far as possible.
As seen from Figure 1, the top of wind coal dust air-out pipeline section 2 is provided with suspension ring 4, for providing support power when opening of device, reduces weighing of hinge.
As seen from Figure 2, connect pipeline section 1 place at air intake and be provided with adpting flange 5, for installing with the installing hole place of the burner of Small Combustion stove in use.
In sum, be not difficult to find out, the spiral casing type coal fines burner that above-described embodiment provides forces the mode of High Rotation Speed to send into burner hearth by spiral case passage coal dust and wind, thus meet the requirement of combustion path length in little space, substantially increases the burn-off rate of coal dust.Meanwhile, because of abundant mixing and the High Rotation Speed of wind and coal dust, achieve good atomization, be conducive to burning.In addition, solid particle is than wind weight, and during rotation, majority concentrates on outer, and local improves the concentration of coal dust, is conducive to ignition.This burner obtains very good effect in user's demonstration project uses.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection domain of the present utility model with the same or analogous design of the utility model.
