Abstract
The invention relates to a six-channel nozzle for a rotary kiln. A cylindrical nozzle body is sequentially provided with a central air channel, a coal powder channel, a coke oven gas channel, a converter gas channel, a swirl air channel and a direct-flow air channel from the center to the outside, wherein the central air channel, the coal powder channel, coke oven gas channel and the converter gas channel are in a horn opening shape; and a swirl air channel swirl sheet is fixed on the swirl air channel. The six-channel nozzle can switch coal powder, coke oven gas and converter gas under the condition of normal calcining.
Description
Technical field
The present invention relates to a kind of burner, be particularly suitable for turning round stove and use.
Background technology
Requirement to temperature in the metallurgical active lime production is the low-temperature stabilization calcining, and temperature need be controlled at 1250 ± 50 ℃, lime is produced give birth to and burn and burning, reduces the activity degree of lime.The control rotary kiln temperature makes not only sufficient combustion but also can not produce undue high temperature and make the lime burning of lime, uses difficulty of burner combustion control ratio at present.The fuel gas coke-stove gas, coal gas of converter, the blast furnace gas that in steel plant's fuel has coal dust and produces, produce in addition because of rotary kiln has only a burner, are difficult to guarantee that mutual alternative is used under the situation of normal calcining.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of industrial furnace six passage burners, and it can make coal dust, coke-stove gas and coal gas of converter or blast furnace gas mutual alternative under the situation of normal calcining.
The present invention solves the technical scheme that its technical problem takes: columned burner body therefrom mind-set has center wind duct, coal dust passage, coke-stove gas passage, coal gas of converter passage, eddy flow wind passage and direct current wind passage outward successively; Described center wind duct, coal dust passage, coke-stove gas passage and coal gas of converter passage are bell mouth shape; On described coal dust passage, coke-stove gas passage, coal gas of converter passage and the eddy flow wind passage spinning disk device is arranged, adjacent spinning disk rotation direction is opposite.
The present invention makes three kinds of fuel and Air mixing form eddy current; Make combustion gas good mixing under the eddy current state, flame length is suitable, good rigidly; Flame profile is complete; Combustion gas is fully burnt, and temperature is suitable, still can satisfy ordinary production when three kinds of fuel take place than cataclysm or when having only two kinds of fuel.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a structural representation of the present invention;
Fig. 2 for A among Fig. 1 of the present invention to view.
The specific embodiment
Shown in accompanying drawing 1; Columned burner body 1 therefrom mind-set has center wind duct 5, coal dust passage 7, coke-stove gas passage 8, coal gas of converter passage 6, eddy flow wind passage 3 and direct current wind passage 2 outward successively; Described center wind duct 5, coal dust passage 7, coke-stove gas passage 8 and coal gas of converter passage 6 are bell mouth shape, fixing eddy flow wind passage spinning disk 10 on the described eddy flow wind passage 3.
Be fixed with coal dust passage spinning disk 11, coke-stove gas passage spinning disk 9 and coal gas of converter passage spinning disk 4 respectively on the collar extension of described coal dust passage 7, coke-stove gas passage 8 and coal gas of converter passage 6, adjacent spinning disk rotation direction is opposite.
Do not establish spinning disk on the described direct current wind passage 2.
