Description
Technical field
The shower nozzle of a kind of rotary kiln coal dust and the burner of gas multifuel combustion is the utility model is related to, belongs to combustion science skill
Art field.
Background technology
Influenceed by National energy distribution and supply present situation, domestic rotary kiln burner uses coal dust as fuel mostly.
With energy supply be becoming tight and the Scientific Outlook on Development deepen continuously that the industry such as the popular feeling, metallurgy, chemical industry is caused in the industrial production can
Combustion property gas byproduct is utilized as secondary energy sources, the implementation of China's West-East National Gas Transmission Project in addition, promotes coal gas
Mixed combustion type burner is more widely applied.Combustion gas is used in burner, reduces the environmental pollution of rotary kiln, improves fuel
Economy.
In actual applications, want coal dust and combustion gas can be fully burned, meet in actual production to the combustion heat
The demand of amount, the gas usage needed for the rotary kiln of different size is also different, is stood in the unit interval from several hectosteres to tens of thousands of
Square rice.Burning fuel gas to be mixed, changes the burning situation of single fire coal dust in rotary kiln, fuel gas mixes burning amount difference,
The structure of corresponding burner is also otherwise varied.Irrational mix is mixed burning amount with combustion gas and changed, the heating of fuel combination in kiln
Amount can reduce, and the burn-off rate of coal dust reduces, and so as to cause kiln temperature level to be remarkably decreased, seriously affects heat supply in kiln.It is real
Trample and show that suitable burner structure should be selected according to kiln type, Coal-fired capacity can be reduced while rationally combustion gas is utilized, maintained
Higher rotary kiln heating efficiency.Timely, the stable ignition of wherein fuel are burner safety, the essential condition of economical operation.
Under the big use demand of gas consumption, preferably using the Patent No. " 200920289762.2 " of our company's application, specially
The patented product structure of sharp entitled " rotary kiln coal dust and gaseous fuel combustion combustor ", imitated with obtaining good burning
Energy.
The content of the invention
The utility model is directed to above-mentioned technical problem, and the utility model provides a kind of gas consumption small rotary kiln coal gas
The shower nozzle of combustion combustor, realize the matched well of gas consumption and burner structure.
The technical solution adopted in the utility model is that a kind of shower nozzle of rotary kiln coal gas composite burning burner, its feature exists
In：It is logical that axle stream wind passage, Whirl deposite tank passage, coal wind duct, blast tube, center wind duct and igniting are sequentially provided with from outside to inside
Road totally six passage, respectively by axle stream wind outer barrel 2, axle stream wind inner cylinder 3, coal wind inner cylinder 4, Whirl deposite tank inner cylinder 5, coal gas inner cylinder 6, igniting
Pipeline 7 is formed after being sequentially coaxially set with from outside to inside；Axle stream wind outer barrel 2, axle stream wind inner cylinder 3, coal wind inner cylinder 4, Whirl deposite tank inner cylinder
5th, coal gas inner cylinder 6 is that cylindric and caliber is sequentially reduced；The cavity that axle stream wind outer barrel 2 is formed after being set with axle stream wind inner cylinder 3
For axle stream wind passage, the cavity that axle stream wind inner cylinder 3 is formed after being set with coal wind inner cylinder 4 is Whirl deposite tank passage, coal wind inner cylinder 4 and rotation
The cavity that stream wind inner cylinder 5 is formed after being set with is coal wind duct, and the cavity that Whirl deposite tank inner cylinder 5 is formed after being set with coal gas inner cylinder 6 is
Blast tube, coal gas inner cylinder 6 and wind passage centered on the cavity formed after the igniting suit of pipeline 7, the inner cylinder space for pipeline 7 of lighting a fire
Form ignition channel.
The outer layer of described axle stream wind outer barrel 2 be provided with cylindrical shape hold together flame cover 1.
The utility model has the advantage of：
When gas consumption is smaller, blast tube is arranged at the inner side of axle stream wind, Whirl deposite tank and coal wind duct, and blast tube is tight
Adjacent center wind duct and ignition channel, after igniting, it is ignited in shorter distance on the inside of the coal wind duct, it is on fire in time, ensure
Flame holding, beneficial to the abundant burning of combustion gas, make to burn till strip length needed for being formed in kiln, kiln temperature is reasonably distributed.
Brief description of the drawings
Fig. 1 is head construction schematic diagram of the present utility model.
Embodiment
Be sequentially provided with from outside to inside axle stream wind passage, Whirl deposite tank passage, coal wind duct, blast tube, center wind duct and
Ignition channel totally six passage, respectively by axle stream wind outer barrel 2, axle stream wind inner cylinder 3, coal wind inner cylinder 4, Whirl deposite tank inner cylinder 5, coal gas inner cylinder
6th, light a fire after pipeline 7 is sequentially coaxially set with from outside to inside and formed；Axle stream wind outer barrel 2, axle stream wind inner cylinder 3, coal wind inner cylinder 4, eddy flow
Wind inner cylinder 5, coal gas inner cylinder 6 are that cylindric and caliber is sequentially reduced；Axle stream wind outer barrel 2 is formed after being set with axle stream wind inner cylinder 3
Cavity be axle stream wind passage, the cavity that axle stream wind inner cylinder 3 is formed after being set with coal wind inner cylinder 4 is Whirl deposite tank passage, in coal wind
The cavity that cylinder 4 is formed after being set with Whirl deposite tank inner cylinder 5 is coal wind duct, what Whirl deposite tank inner cylinder 5 was formed after being set with coal gas inner cylinder 6
Cavity is blast tube, coal gas inner cylinder 6 and wind passage centered on the cavity formed after the igniting suit of pipeline 7, the pipe for pipeline 7 of lighting a fire
Interior space forms ignition channel.The outer layer of axle stream wind outer barrel 2 be provided with cylindrical shape hold together flame cover 1.
For the less rotary kiln burner of gas consumption, the bowl-shape effect of flame cover formation is held together outside axle stream wind, prevents from firing
Material diffusion too early, under the comprehensive function of outer layer axle stream wind, Whirl deposite tank and coal wind, the internal layer positioned proximate central wind and point of blast tube
Fiery passage, thus be easy to produce stable flame in the end of burner after lighting a fire.
In rational gas quantity, structure of the present utility model is in clean burn coal dust, clean burn coal gas and coal dust gas multifuel combustion（Combustion
Tolerance is smaller）High combustion efficiency, the target of the stable safety of production can be reached under three kinds of operating conditions.
