The front end of the elbow is connected with the tail end of a combustor, and the back end of the external sleeve is connected with a coal dust pipe. The device has the advantages and beneficial effects that the device is applied in the ignition with tiny-oil or plasma ignition system, thereby realizing the function of distributing and adjusting the coal dust concentration, which not only save oil, does not change the effect of the coal dust distribution property in an original combustor, and does not affect the boiler.
Description
Technical field
The utility model relates to a kind of coal burner that is applicable to few-oil ignition or plasma ignition.
Background technology
The coal burner that is used for few-oil ignition system and plasma ignition system at present, the employing center is dense, light concentrated mode all around.Because few-oil ignition or plasma ignition all are internal combustion ignition principles, this just need Pulverized Coal Concentration and in case light after can not cause the burner wall to burn out, so present start-up burner is arranged in the burner center, this also makes the Pulverized Coal Concentration mode want centering dense.This improved start-up burner concentrates the firing characteristic that mode is well positioned to meet burner, in case but it is when moving as main burner, equally also can only keep dense, the light characteristic all around in center, and a lot of coal burners turbulent burner particularly, the characteristic that the coal dust distribution character is dense around all being, the center is light.Under many circumstances because above-mentioned transformation, changed the coal dust distribution character of former burner, though satisfied the requirement of igniting, owing to changed the coal powder light-dark distribution character of former burner, be unfavorable for the burning of boiler global tissue, even can reduce boiler combustion efficiency.
Summary of the invention
The purpose of this utility model provides a kind of adjustable concentrating device that is applicable to few-oil ignition or plasma ignition, solving when the igniting, the coal dust profile adjustment is arrived dense, the light satisfied igniting distribution character state all around in center; When moving as main burner, then with the coal dust profile adjustment to around the technical problem of dense, the center is light when satisfying burner operation igniting distribution character state.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
This adjustable concentrating device comprises elbow, curved tube, guide vane and outer sleeve; Described curved tube places in the elbow, press the overlapping fixed placement of axis, the elbow lower end connects an outer sleeve, in outer sleeve, be positioned at curved tube porch below, be provided with to be positioned at and bend tube axis extended line both sides, two or several guide vanes of symmetric arrays, the fulcrum rotating shaft is established at described each guide vane middle part, some guide vanes rotate synchronously along fulcrum rotating shaft separately, but constitute the top opening that formed by some guide vanes or the coal dust profile adjustment device of reducing; In the reducing of coal dust profile adjustment device upper oral part hour, the distance between the guide vane top is slightly less than the square length of side in curved tube lower end, and when opening was maximum, the guide vane bottom is to be closed or closely adjacent approximate closed condition; Described elbow front end is connected with burner is terminal, and the outer sleeve rear end is connected with pulverized coal channel.
Aforesaid adjustable concentrating device, described elbow, curved tube, guide vane and outer sleeve are all made by high-abrasive material.
Aforesaid adjustable concentrating device, described outer sleeve main body is a square structure, the import and export end is equipped with the circumference joint.
Aforesaid adjustable concentrating device, described curved tube bottom inlet is for square, and guide vane is a sheet, by two symmetrical distributions.
Aforesaid adjustable concentrating device, described guide vane are the laminated structure of knuckle shape.
Advantage of the present utility model and good effect are:
The adjustable concentrating device that is used for few-oil ignition or plasma ignition, realized coal powder density distribution adjustable function,, realized both fuel-economizings for few-oil ignition or plasma ignition system transformation, do not change the effect of former burner coal dust distribution character again, boiler integral body is not had any impact.

The specific embodiment
Concrete structure of the present utility model is referring to Fig. 1, and it comprises curved tube 2, elbow 1, guide vane 4 and outer sleeve 3.Each parts among Fig. 1 all adopt high-abrasive material to make.Curved tube 2 main bodys are tubular, and the bottom is a square opening shape, and elbow 1 is nested with together mutually with curved tube 2, and is fixed together by axis is overlapping.The front end of elbow 1 is a ring flange, is connected with terminal realization of burner.Elbow 1 lower end connects an outer sleeve 3, in outer sleeve 3, be positioned at curved tube 2 porch below, be provided with and be positioned at elbow axis extended line both sides, several guide vanes 4 of symmetric arrays, fulcrum rotating shaft 5 is established at described each guide vane 4 middle part, some guide vanes 4 rotate synchronously along fulcrum rotating shafts 5 separately, but the top opening that formation is formed by some guide vanes 4 or the coal dust profile adjustment device of reducing; In the reducing of coal dust profile adjustment device upper oral part hour, the distance between guide vane 4 tops is slightly less than the square length of side in curved tube lower end, makes in the curved tube 2 of the most of input of coal dust, and the formation center is dense, light distribution character all around; When opening was maximum, distance was very little or close between guide vane 4 bottoms, makes coal dust all enter curved tube 2 outsides along blade, thereby the formation center is light, dense distribution character all around.
Fig. 2 has reflected the structure of outer sleeve 3 and guide vane 4, and outer sleeve 3 main bodys are square structure, is equipped with the circumference joint at entrance end (referring to Fig. 1).Guide vane is a sheet and with two 4-1, the 4-2 setting that is symmetrically distributed, the middle part of each guide vane is provided with rotating shaft 5-1,5-2.
Fig. 3 to Fig. 5 is an embodiment of guide vane 4, and the guide vane 4 among this embodiment has a bending place in the bottom.
In the embodiment that in above-mentioned figure, provides, the angle of bend of elbow 1 and curved tube 2 usually should greater than 20 ° less than 120 °, be the best with 90 °.Guide vane described in the utility model 4 cooperates with curved tube 2 and elbow 1 as diversion component, can satisfy the adjustment requirement of the centralization and decentralization that coal dust is flowed in tube.On the basis of such scheme, other shapes or the setting of guide vane all are not precluded within the protection domain of this patent.
