And outer axial compressor wind channel, whirl wind channel, vortex wind channel are the conical spiral passageway, and the whirl wind channel is opposite with the direction of rotation in vortex wind channel. Addding vortex wind channel, making the mixture of spun air current more even, change in the rotation angle who changes the blowout air current, change the flow of blowout air current moreover, can adjust the shape of torching better, especially the direction of rotation in vortex wind channel is opposite with the direction of rotation in whirl wind channel for produce the torrent between the two and the buggy, make the indiscriminate powder in buggy layer can burn more fully. Three -layer conical spiral passageway more is favorable to adjusting the velocity of flow and the flow dimension of blowout air current, and the regulation is changeed to flame profile and size.
Description
Technical field
The present invention relates to burner arts.
Background technology
In traditional cement production process, mostly use simple single air channel, two air-channel coal powder combustor, how black the burner duration and degree of heating of these kinds be long, and efficiency of combustion is low; In succession develop the rear eighties, the nineties triple channel, four-way coal burner, but still there is air channel structure design and make that its air feed is stable not, flame profile temperature is wayward, can not be real-time regulate according to the change of production environment and process conditions, cannot adapt to the problem of coal quality inequality.Telescopic joint is mainly used in the dilatation that compensation pipeline produces because of variations in temperature, also for length compensation that pipeline needs because of mounting and adjusting etc., patent CN101566342A discloses a kind of gas burner of furnace, the connection of burner and blower fan employs metal bellows expansion joints, is in order to avoid nozzle is given a shock.
Existing burner, centre bore is jet, and centre bore is swirl air duct from inside to outside successively, coal dust air channel, outer shaft wind air channel, such structure, and arranges mobile device on pipeline, realizes pipeline axial and moves.Although can change the shape jetted out flames, the degree changed is undesirable, and coal dust firing is insufficient.
Summary of the invention
For solving the problem, the invention provides a kind of novel multicenter combustor.
Concrete scheme of the present invention is: a kind of burner, comprise centre bore as fuel injection passage, fuel injection passage is outwards followed successively by swirl air duct, coal dust air channel, and wherein swirl air duct is the eddy flow helical duct that direction of rotation is identical, in eddy flow passage, outside fuel injection passage, set up eddy current air channel.
Described eddy current air channel is made up of the swirling helical passage that each direction of rotation is identical.
The direction of rotation of described swirling helical passage is identical with the direction of rotation of eddy flow helical duct.
The direction of rotation of described swirling helical passage is contrary with the direction of rotation of eddy flow helical duct.
Eddy flow helical duct and swirling helical passage are cone-type spiral passage.
Outer shaft stream air channel is enclosed outside described coal dust air channel.
Described outer axial flow air channel is made up of the outer axial-flow cone shape helical duct that each direction of rotation is identical.
The central axis of described cone-type spiral passage is circular helix, and its lift angle is 15 °-25 °.
The tapering of described cone-type spiral passage changes between 8 °-15 °.
The invention has the beneficial effects as follows, set up eddy current air channel, make the mixing of the air-flow of ejection evenly, be easier to the anglec of rotation changing ejection air-flow, and change the flow of ejection air-flow, can adjust the shape jetted out flames better, especially the direction of rotation in eddy current air channel is contrary with the direction of rotation of swirl air duct, make turbulization between the two and coal dust, make the random powder of coal dust layer can burn more abundant.Three layers of cone-type spiral passage, be more conducive to the flow velocity and the uninterrupted that regulate ejection air-flow, flame profile and size more easily regulate.
