Description
Technical field
The present invention relates to burner arts.
Background technology
In traditional cement production process, simple single air channel, double air-channel coal powder combustors are used mostly, these kinds
How black burner duration and degree of heating length, efficiency of combustion be low；Develop the eighties, the nineties triple channel, four-way coal burner in succession afterwards,
But still exist air channel structure design be not sufficiently stable its air feed, flame profile temperature is difficult to control, it is impossible to real-time basis
The change of production environment and process conditions is adjusted, the problem of can not adapting to coal quality inequality.Telescopic joint is mainly used in mending
Pipeline is repaid because of temperature change and caused by dilatation, be also used for length compensation of the pipeline because of needs such as mounting and adjustings, patent
CN101566342A discloses a kind of gas burner of furnace, has used wavy metal to stretch in the connection of burner and blower fan
Section, is in order to avoid nozzle is given a shock.
Existing burner, centre bore are jets, and centre bore is swirl air duct successively from inside to outside, coal dust air channel, outer shaft
Wind air channel, such structure, and mobile device is set on pipeline, realize that pipeline moves axially.Although ejection can be changed
The shape of flame, but the degree changed is undesirable, and also coal dust firing is insufficient.
The content of the invention
To solve the above problems, the present invention provides a kind of new multicenter combustor.
The present invention concrete scheme be：A kind of burner, including centre bore is as fuel injection passage, fuel injection passage is outwards successively
For swirl air duct, coal dust air channel, wherein swirl air duct is direction of rotation identical eddy flow helical duct, in swirl channel, spray
Vortex air channel is set up outside oily passage.
The vortex air channel is made up of each direction of rotation identical swirling helical passage.
The direction of rotation of the swirling helical passage is identical with the direction of rotation of eddy flow helical duct.
The direction of rotation of the swirling helical passage is opposite with the direction of rotation of eddy flow helical duct.
Eddy flow helical duct and swirling helical passage are cone-type spiral passage.
Coal dust air channel periphery sets outer shaft stream air channel.
The outer shaft stream air channel is made up of axial-flow cone shape helical duct outside each direction of rotation identical.
The central axis of the cone-type spiral passage is circular helix, and its lift angle is 15 ° -25 °.
The taper of the cone-type spiral passage changes between 8 ° -15 °.
The invention has the advantages that setting up vortex air channel, make the mixing of air-flow of ejection evenly, it is easier to change spray
Go out the anglec of rotation of air-flow, and change the flow for spraying air-flow, can preferably adjust the shape to jet out flames, especially be vortexed
The direction of rotation in air channel is opposite with the direction of rotation of swirl air duct so that the two turbulization between coal dust so that coal dust layer
Random powder can burn more abundant.Three layers of cone-type spiral passage, it is more beneficial for flow velocity and uninterrupted that regulation sprays air-flow, flame
Shapes and sizes are more easy to adjust.
