Abstract
The invention relates to a pre-combustion burner, which comprises a fuel receiving pipe, a nozzle, an ignition hole and a burner brick, wherein a pre-combustion chamber, namely a combustion cylinder, is arranged between the nozzle and the burner brick; the exterior of the combustion cylinder is provided with an air chamber; air entering from an air inlet above the air chamber performs three-level combustion support on the fuel in the combustion cylinder, namely a cyclone for whirl air mixed combustion support, an air inlet on the combustion cylinder for direct-current air combustion support and a circular seam between the air chamber for tangential air combustion support and the combustion cylinder are adopted; and the three-level combustion supporting air synchronously cools the exterior of the combustion cylinder. The pre-combustion chamber is increased in the burner, the fuel in the pre-combustion chamber is partially combusted, the combustion supporting air is supplied for three times, the second and third air supply can play a role in cooling besides combustion support, the combustion supporting air forms non-uniform speed field, temperature field and concentration field in the pre-combustion chamber, reflux is formed in the center and circular current is formed on four sides. The burner produces half flame-free torch, has high speed and high rigidity, saves energy and improves the yield.
Description
Technical field
The present invention relates to the combustion apparatus of industrial furnace cellar for storing things usefulness, refer in particular to a kind of preheating type burner.
Background technology
At present still do not have a kind of burner can satisfy all performance requirements, but the burner of a function admirable should satisfy performance requirement as much as possible.Burner is the key equipment of industrial furnace, and its performance has influence on the civilization degree of output, quality, energy consumption, environmental protection and the production of industrial furnace fatefully.The burner of a function admirable can be high yield, high-quality, low consumption, the of low pollution of industrial furnace and the creation prerequisite of carrying out production strictly in line with rules and regulations.Burner of a great variety, this mainly because different fuel type, calorific value size, performance requirements cause.
Summary of the invention
The objective of the invention is to be improved and innovate at the shortcoming that exists in the background technology and problem, a kind of function admirable is provided, but using gases, liquid and solid fuel, has a precombustion chamber that combustion intensity is higher, make half gasification of liquid or solid fuel, it is complete to resemble the coal gas easy burning, and has that the black furnace ignition performance is good, flameholding, improves efficiency of combustion, regulates the preheating type burner than, thermoregulation range.
The present invention constructs a kind of burner that comprises fuel adapter, nozzle, fire hole and burner block, and it is combustion barrel that a precombustion chamber is set between its nozzle and the burner block, and the combustion barrel outside is provided with air compartment, wherein:
The air that enters by the air inlet that is arranged on air compartment top to fuel in the combustion barrel divide three grades combustion-supporting, comprise that promptly being made as eddy flow wind mixes combustion-supporting cyclone, is made as the air admission hole on the combustion-supporting combustion barrel of direct current wind and is made as combustion-supporting air compartment of tangential wind and the circumferential weld between the combustion barrel, and three grades of combustion airs cool to the combustion barrel outside synchronously.
Advantage of the present invention and beneficial effect:
The present invention increases a pre-right chamber in burner, fuel carries out partial combustion interior, and combustion air divides air feed three times, and secondary, three air feeds also can play cooling effect except that combustion-supporting, combustion air forms uneven velocity field temperature field and concentration field in precombustion chamber, the center has to reflux circulation all around.Produce half nonflame torch, the high rigidity of its speed is big, strengthens the circulation of furnace gas, increases the convection heat transfer' heat-transfer by convection amount, and wind and secondary wind all can be preheated to the high temperature energy savings, improve output.
Description of drawings
Fig. 1 is combustion gas of the present invention, fuel oil type dual burner structural representation.
Fig. 2 is a combustion type burner structure schematic diagram of the present invention.
The specific embodiment
By accompanying drawing 1,2 as can be known, the present invention includes fuel adapter 1, nozzle 4, fire hole 3 and burner block 8, it is combustion barrel 7 that a precombustion chamber is set between its nozzle 4 and the burner block 8, and combustion barrel 7 outsides are provided with air compartment 6, wherein:
The air that enters by the air inlet 9 that is arranged on air compartment 6 tops to fuel in the combustion barrel 7 divide three grades combustion-supporting, comprise that promptly being made as eddy flow wind mixes combustion-supporting cyclone 5, is made as the air admission hole on the combustion-supporting combustion barrel of direct current wind 7 and is made as circumferential weld between tangential wind combustion-supporting air compartment 6 and the combustion barrel 7, and three grades of combustion airs cool to combustion barrel 7 outsides synchronously.
Structural principle of the present invention:
The present invention can using gases, liquid, solid, and it is to maximize favourable factors and minimize unfavourable ones on the basis of high velocity burner and a kind of novel burner of development to some extent.It has a precombustion chamber that combustion intensity is higher, carries out the fuel combustion of part therein, and it is complete to make half gasification of solid, liquid resemble the coal gas easy burning, can improve efficiency of combustion, reduces the temperature of precombustion chamber simultaneously, solves high temperature resistant furnace lining problem.It is combustion-supporting to be divided into eddy flow wind, tangential wind and direct current wind with air, carries out the classification air feed, step by step burning.And combustion intensity is high and the NOx growing amount reduces, and the pressure of air and fuel is low and adopt sectional combustion that noise reduction and pollution are reduced.Also annular deduster can be set in the exit, when using fine coal, can remove the part dust, reduce dust emission concentration, help environmental protection.
Operation principle of the present invention:
Combustion air enters air compartment from airduct, is divided into three strands of air then, and primary air flows into cyclone and enters in the combustion barrel, forms the recirculating zone of a retention flame there, and with fuel mix, burning from the nozzle ejection, form the flue gas of uniform temperature; Auxiliary air enters in the tube by the air admission hole on the combustion barrel, and promptly the cooling combustion tube further burns with fuel again; Tertiary air flows through from the circular passage between air compartment and combustion barrel, behind the cooling combustion tube outer surface, in circumferential weld flows into burner block, looks different the purposes of burner, or plays combustion-supporting effect again, or play the blending cooling effect, to reach the burner exit gas temperature of expection.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design philosophy of the present invention; engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
