The gas two-air-channel cyclone burner is simple in structure, convenient to install and maintain and applicable to various kinds of gas; and based on the multi-stage air distribution principle, the gas two-air-channel cyclone burner is high in efficiency and low in pollution, has high stable combustion capacity and ensures low emission quantity of nitric oxide (NOx).
Description
Technical field
The utility model relates to technical field of burner, particularly a kind of combustion gas two air channel vortex burners.
Background technology
The industrial furnace burner equipment and technology of China is backward relatively; The burners in prior complex structure; Be unfavorable for installing and safeguarding; And can only be directed against special combustion gas kind, problem such as air distribution is unreasonable to cause that efficiency of combustion is low, combustion instability and NOx discharge capacity are big, and the deep development of industrial furnace burner is related to the Green Development of high energy consumption industries such as oil-refining chemical, electric power, metallurgy, environmental protection; Therefore, the industrial furnace burner of researching and developing a kind of high-efficiency low-pollution is that the benign development of high energy consumption industries such as oil-refining chemical, electric power, metallurgy, environmental protection provides prerequisite to guarantee to become a kind of inexorable trend.
Summary of the invention
The utility model purpose is to above-mentioned technical disadvantages a kind of combustion gas two air channel vortex burners to be provided.
The technical scheme of the utility model is following:
A kind of combustion gas two air channel vortex burners; Form by wind passage, secondary air channel, wind dilatation road, interior secondary air duct, outer secondary air duct, cyclone, gas nozzle, wind damper, interior secondary wind damper and an outer secondary wind damper; Wind passage is connected with wind dilatation road and secondary air channel; Both sides, a wind dilatation road are fixed with interior secondary air duct; Interior secondary air duct is equipped with outer secondary air duct outward, and in the secondary air duct, gas nozzle was positioned at the burner front end in cyclone was installed in.
A described wind passage and wind dilatation road and secondary air channel junction are provided with the wind damper one time.
Secondary wind damper and outer secondary wind damper in secondary air duct and outer secondary air duct and secondary air channel junction are provided with in described.
The beneficial effect of the utility model is: product structure is simple; Be convenient to install, safeguard, it is extensive to adapt to the combustion gas kind, adopts multistage air distribution principle; Realized high-efficiency low-pollution; Steady combustion ability is strong, and the NOx discharge capacity is low, for the benign development of high energy consumption industries such as oil-refining chemical, electric power, metallurgy, environmental protection provides the prerequisite assurance.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Among the figure, 1 is a wind passage, and 2 is secondary air channel, and 3 is a wind dilatation road; 4 is interior secondary air duct, and 5 is outer secondary air duct, and 6 is the eddy flow cyclone, and 7 is gas nozzle; 8 is a wind damper, and 9 is interior secondary wind damper, and 10 is outer secondary wind damper.
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
A kind of combustion gas two air channel vortex burners; Form by a wind passage (1), secondary air channel (2), a wind dilatation road (3), interior secondary air duct (4), outer secondary air duct (5), cyclone (6), gas nozzle (7), a wind damper (8), interior secondary wind damper (9) and outer secondary wind damper (10); A wind passage (1) is connected with a wind dilatation road (3) and secondary air channel (2); Both sides, a wind dilatation road (3) are fixed with interior secondary air duct (4); Interior secondary air duct (4) is outer to be equipped with outer secondary air duct (5), and cyclone (6) is installed in the interior secondary air duct (4), and gas nozzle (7) is positioned at the burner front end.
A described wind passage (1) is provided with a wind damper (8) with a wind dilatation road (3) and secondary air channel (2) junction.
Secondary wind damper (9) and outer secondary wind damper (10) in secondary air duct (4) and outer secondary air duct (5) are provided with secondary air channel (2) junction in described.
Described gas nozzle (7) can carry out specialized designs according to actual needs, can realize the adjusting of length flame.
When wind and combustion gas get into a wind passage (1); Because the effect of self inertia power and an interior secondary wind and a blast is in a wind passage (1) air stream all around and gets into secondary air channel (2) together with the fraction combustion gas, most of combustion gas is then because action of inertia gets into a wind dilatation road (3); At this moment; The primary air velocity degree descends, and diffusion makes the gas concentration at center, a wind dilatation road (3) higher around the air, realizes the burning of high-efficiency low-pollution.
One time wind combustion gas concentrating degree can change a wind passage (1) and be communicated with area with secondary air channel (2) through regulating a wind damper (8), thereby reaches wind combustion gas concentrating degree of control, and it is extensive to make burner adapt to the combustion gas kind, and the ability of surely firing is strong.
Wind decrease speed and the air capacity and the gas quantity that are separated to secondary wind; Can regulate through interior secondary wind damper (9) and outer secondary wind damper (10); Through secondary wind damper (9) in changing and outer secondary wind damper (10) aperture,, thus primary and secondary air air velocity and the differential static pressure that changes primary and secondary air controlled; Multistage air distribution reduces the NOx discharge capacity greatly.
Through above embodiment, the utility model superior performance, simple in structure, installation, easy to maintenance; It is extensive to be suitable for the combustion gas kind, and multistage air distribution improves efficiency of combustion, flameholding greatly; NOx control effect is good, greatly reduces the NOx discharge capacity, has realized high-efficiency low-pollution.
