Abstract
The utility model discloses a cyclone burner, which comprises a flame stabilizer, a central air channel, a coal air channel, a cyclone air channel, an axial air channel and an outer air purifying channel from inside to outside in sequence, wherein a supporting rib of the cyclone air channel forms an anticlockwise angle of 20 degrees with the axial direction, and the cyclone air channel is divided into an inner ring cyclone air channel and an outer ring cyclone air channel; the support ribs of the inner ring rotational flow air channel form an anticlockwise angle of 20 degrees with the axial direction, and the support ribs of the outer ring rotational flow air channel form a clockwise angle of 15 degrees with the axial direction. This spiral-flow type combustor owing to increaseed the whirl passageway, is two parts to the cutting of whirl wind, can be according to positive and negative two directions outflow gas, makes fuel can the intensive mixing postcombustion, and the burning is more abundant.
Description
Technical field
The utility model relates to a kind of burner, relates in particular to a kind of vortex burner.
Background technology
Burner is the capital equipment of cement plant firing system, and it has very important effect to service life, raising running rate, the expansion utilization of resources, the shortening kiln cylinder body length of saving energy and reduce the cost, improve grog yield and quality, prolongation rotary kiln refractory brick and kiln body, the discharging that reduces pernicious gas NOx.Rotary kiln burner develops into today, existing four generation product.
The four-way burner is up-to-date generation combustion apparatus, is specifically designed to rotary kiln.Four-way burner, main feature are to reach purpose of energy saving by reducing the primary air amount significantly, by reducing NO
xDischarge capacity reaches the purpose that reduces environmental pollution.The four-way burner adopts latest modern--and high speed difference and strong eddy flow theory are assembled the fuel of the internal range of flame; Reduce the oxygen content in the flame root scope and reduce temperature peak by reducing the primary air consumption; Geometry by nozzle reduces intake one time.
As shown in Figure 2, the vortex burner of prior art, its structure is followed successively by from the inside to the outside: flameholder 1, center wind duct 2, coal wind duct 3, eddy flow wind passage 4, axial flow wind passage 5, outer clean wind passage 6, eddy flow wind passage 4 is approximately apart from burner opening 200mm place after a broad air channel and the strong point lean on, like this exit flame profile is difficult to guarantee, cause coal dust firing insufficient, NO
x, the CO discharge capacity is higher.
The utility model content
The purpose of this utility model is to provide a kind of sufficient combustion, and NO
x, vortex burner that the CO discharge capacity is lower.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of vortex burner, be followed successively by flameholder, center wind duct, coal wind duct, eddy flow wind passage, axial flow wind passage and outer clean wind passage from the inside to the outside, the brace rod of eddy flow wind passage with axially become counterclockwise 20 ° of angles, described eddy flow wind passage is divided into inner ring eddy flow wind passage and outer ring eddy flow wind passage; The brace rod of described inner ring eddy flow wind passage with axially become counterclockwise 20 ° of angles, the brace rod of described outer ring eddy flow wind passage becomes clockwise 15 ° of angles with axial.
The material of vortex burner burner is the heat-resistant antifriction high-alloy steel of model 2Cr12NiMoWV.
The vortex burner that adopts the utility model to provide owing to strengthened the eddy flow passage, is cut into two parts to eddy flow wind, can make fuel can fully mix after-combustion by positive and negative both direction eluting gas, and it is more abundant to burn.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is eddy flow wind passage angle schematic diagram of the present utility model.
Fig. 3 is the prior art constructions schematic diagram.
Among the figure, 1-flameholder, 2-center wind duct, 3-coal wind duct, 4-eddy flow wind passage, 5-axial flow wind passage, the outer clean wind passage of 6-, 7-outer ring eddy flow wind passage, 7 '-inner ring eddy flow wind passage.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
As shown in Figure 1, the vortex burner that the utility model provides, its structure is followed successively by flameholder 1, center wind duct 2, coal wind duct 3, eddy flow wind passage, axial flow wind passage 5 and outer clean wind passage 6 from the inside to the outside, the brace rod of eddy flow wind passage sprays with axially becoming counterclockwise 20 ° of angles, and eddy flow wind passage is divided into inner ring eddy flow wind passage 7 ' and outer ring eddy flow wind passage 7.The internal diameter of inner ring eddy flow wind passage 7 ' is the same with eddy flow wind passage internal diameter to be φ 245, and the external diameter of outer ring eddy flow wind passage 7 is the same with eddy flow wind outside diameter of passage to be φ 450.Total ventilation is constant, is 8.3 ten thousand mm
2.
As shown in Figure 2, the thickness of the brace rod of inner ring eddy flow wind passage 7 ' is that 6mm, length are 85mm, becomes the ejection of counterclockwise 20 ° of angles with axial.The thickness of the brace rod of outer ring eddy flow wind passage 7 is 6mm, and length is 85mm, becomes clockwise 15 ° of angles with axial.By positive and negative both direction effluent air, can make fuel can fully mix after-combustion like this, it is more abundant to burn, and the air quantity of rotation ejection is more powerful.、
Because being in the environment temperature at flame encompasses position, combustor nozzle is about 1200 ℃, the material of vortex burner burner is that model is the stainless steel of 1Cr18Mn10Ni5Mo3 in the prior art, the heat resistance of this stainless steel is not enough, and scaling loss is not wear-resisting easily.The utility model select for use model be the heat-resistant antifriction high-alloy steel of 2Cr12NiMoWV as the material of vortex burner burner, prolonged the service life of vortex burner burner greatly.
Above-described only is preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection domain of the present utility model.
