Description
Technical field
The utility model relates to a kind of energy-efficient many coals of adjustable type coal burner, especially relates to a kind of energy-efficient many coals of adjustable type coal burner that is applicable to Coal rank that is applicable to use on Industrial Stoves.
Background technology
The burner of current industrial use is generally old-fashioned parallel flow burner, although the breeze airflow range of its ejection is far away, but high temperature gases recirculating amount is few, cause catch fire late, flame is low, furnace flame degree of filling is also poor, and because coal dust is not good with mixing of air, so that coal dust firing is insufficient in burner hearth, and coal consumption is large, leak out when larger at stove, kiln, what spray is general breeze airflow, can not form thermal-flame.
The patent No. is the utility model of ZL03241135.9, although provide a kind of coal dust and air of making to keep better mixed and burning many coals of the energy-efficient adjustable type of double-cyclone coal burner comparatively fully, but this energy-efficient many coals of adjustable type coal burner is only applicable to bituminous coal or the brown coal that fugitive constituent is higher, for anthracite, even the combustion adaptive of lambskin is poor, is not suitable for the burning of many coals.
Utility model content
The utility model is mainly that the existing coal dust firing of solution prior art is insufficient, be suitable for the problem that coal is single, proposed a kind of energy-efficient many coals of adjustable type coal burner that can be applicable to Coal rank, this energy-efficient many coals of adjustable type coal burner can be by the fully burning in same energy-efficient many coals of adjustable type coal burner of the coal dust of Coal rank.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of energy-efficient many coals of adjustable type coal burner, it is characterized in that, the blast pipe, the secondary wind shell that is placed on a crust of weathering outside that comprise crust of weathering, be positioned at an air inlet on a crust of weathering, communicate with air inlet, the diffusing cone that is positioned at secondary air inlet on secondary wind shell, is positioned at a wind whirligig on a blast pipe, communicates with blast pipe, be positioned at the Secondary Air whirligig of secondary wind shell, described secondary wind shell outer cover has a stable flame cover.
In above-mentioned energy-efficient many coals of adjustable type coal burner, described Secondary Air whirligig is the whirligig of the adjustable second wind anglec of rotation.
In above-mentioned energy-efficient many coals of adjustable type coal burner, described diffusing cone is can along continuous straight runs reciprocating.
In above-mentioned energy-efficient many coals of adjustable type coal burner, in described Secondary Air air inlet, be provided with anglec of rotation secondary air regulation mechanism.
In above-mentioned energy-efficient many coals of adjustable type coal burner, a described wind whirligig is helical blade.
In above-mentioned energy-efficient many coals of adjustable type coal burner, described Secondary Air whirligig is helical blade.
In above-mentioned energy-efficient many coals of adjustable type coal burner, a described air inlet communicates with a blast pipe level.
As another kind of scheme, in above-mentioned energy-efficient many coals of adjustable type coal burner, a described air inlet communicates with a blast pipe bending.
Therefore, the utlity model has following advantage: 1. reasonable in design, coal dust firing is more abundant; 2. applicability is strong, can make the coal dust of Coal rank fully burn.
Brief description of the drawings
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment 1.
Schematic diagram when Fig. 2 is the utility model burning.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In figure, crust of weathering 1, air inlet 2, blast pipe 3, cover secondary wind shell 4, secondary air inlet 5, wind whirligig 6, diffusing cone 7, Secondary Air whirligig 8, stable flame cover 9, secondary air regulation mechanism 10, negative pressuren zone 11, spray combustion swirl flame stream 12.
Fig. 1 is an embodiment of the present utility model, the blast pipe 3, the secondary wind shell 4 that is placed on the crust of weathering 1 outside that comprise crust of weathering 1, be positioned at an air inlet 2 on a crust of weathering 1, communicate with air inlet 2, the diffusing cone 7 that is positioned at secondary air inlet 5 on secondary wind shell 4, is positioned at a wind whirligig 6 on a blast pipe 3, communicates with blast pipe 3, is placed on the stable flame cover 9 of secondary wind shell 3 outsides and is positioned at secondary wind shell 4 and the Secondary Air whirligig 8 of the adjustable second wind anglec of rotation.Wherein, diffusing cone 5 is can along continuous straight runs reciprocating, and in Secondary Air air inlet 5, being provided with 10, wind whirligigs 6 of anglec of rotation secondary air regulation mechanism and Secondary Air whirligig 8 is helical blade, and one time air inlet 2 communicates with blast pipe 3 bendings.
As another kind of embodiment, one time air inlet 2 communicates with a blast pipe level.
When use, according to the strict demand of coefficient of excess air, allocate different coal dust firing required air quantities into by secondary air regulation mechanism 10, produce the different anglecs of rotation, the final spray combustion swirl flame stream 12 that forms; Meanwhile, by Secondary Air whirligig 8, regulate the rotation dynamics of Secondary Air, for the high bituminous coal of fugitive constituent or brown coal, accomplish that as possible diffusion type air stream and pulverized coal flow are mixed outward, the suitable rotation dynamics that weakens, forms suitable coal dust recirculating zone and suitable negative pressuren zone 11 at diffusing cone 7.Unburnt coal dust is back in negative pressuren zone, promotes the further after-flame of coal dust.
Low for fugitive constituent, the more difficult coal burning (as anthracite etc.) further lengthen stable flame cover 9, also strengthen Secondary Air rotation dynamics simultaneously, reach the weak eddy flow of coal dust and mix effect with the strong medial rotation of Secondary Air.In mixed inadequate coal stream with air-flow outer further outer the mixing of diffusing cone 7.Wind coal flows under the prevention of diffusing cone due to one time, after pulverized coal flow burning, it is not only thick but also short that flame becomes, and the time that the coal dust of negative pressuren zone 11 stops in stove is longer, the coal dust not burning flows to rapidly negative pressuren zone, to reach the object that the coal dust not burning is burnt rapidly.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
