In primary air premixing cavity 6.
Described air-flow regulation bluff body 7 is cone, and the vertex of a cone of cone is placed in the inner opening part center of inner tube, circular cone
The center subtended angle of body is 60 °～90 ° of angles.
Described air-flow regulation bluff body 7 is that the cone made is tamped in the interior castable refractory cast of heat resisting steel housing.
When being embodied as, coal gas enters once empty by the gas port that gas entry pipe is inner with the form that direct current sprays
Gas premixing cavity 6, and primary air enters primary air distribution circuit 3a via primary air inlet tube 3, then by through once
Air ejiction opening 3c enters primary air premixing cavity with eddy flow or direct current spray pattern, mixes mutually at these two kinds of air-flows and is formed
Initial mixing air-flow, at this through helping mixed homogenizing plate 6a to become more uniform air flow method flow field；Initial mixing air-flow continues
Continue and formed annular membranaceous initial mixed in the exit of primary air premixing cavity 6 through the effect of air-flow regulation bluff body 7 forward
Close uniform air-flow, mixed combustion space 8 is formed the flow field structure of band Central backflow area, under it acts on, realize high quick burning
The steady air flow flow field burnt；Now, auxiliary air enters into auxiliary air distribution circuit 4a via secondary air inlet pipe 4, then
Enter mixed combustion space 8 from auxiliary air ejiction opening 4c ejection, stably fire with the realization through air-flow regulation bluff body 7 in time
The initial mixing air-flow burnt meets and completes the aftercombustion effect to combustion-gas flow (realizing burning completely)；Meanwhile, backflow cigarette
Gas enters backflow flue gas distribution circuit 5a via backflow flue gas inlet tube 5, then through backflow flue gas bleed pipe 5b with direct current or eddy flow
Mode be continuously added in the surrounding of combustion-gas flow, and the burning completing or completing in time and in mixed combustion space 8

The combustion process of temperature-controllable is completed, it is achieved that nitrogen oxides in combustion process while realizing the burning of sufficient stepped mixing
Effective control of growing amount because the backflow that have employed low-temperature flue gas also reaches a high temperature while effectively regulation ignition temperature
Effective utilization of section heat energy.Owing to backflow flue gas can effectively regulate ignition temperature, exhaust gas temperature can be by air preheater
Reducing further, energy-saving effect is the most prominent.Therefore, industrial furnace uses this temperature control, low nitrogen, energy-conservation burning dress
Put, it is possible to according to different gas components and composition, and the concrete structure of industrial furnace and purposes, use meeting technique
On the premise of temperature requirement, further selection and optimization coal gas amount, once with auxiliary air amount and backflow flue gas amount, and pass through
The regulation of implementation process is finally completed effective control of ignition temperature and formation of nitrogen oxides, additionally, the backflow of flue gas is in fall
While low combustion temperature, moreover it is possible to realize the reasonable layout in combustion-gas flow flow field, and can with burner outside heat utilization space
In conjunction with being uniformly distributed of flue gas flow field realizing heat utilization space conditionally.Use this coal gas of the present invention (combustion gas), air
And realize stepped mixing between backflow flue gas, stablize flame, control ignition temperature and reduce the energy-saving combustion apparatus of nitrogen oxides,
The structure space of combustor or even heat utilization device can also be effectively reduced while improving and optimizing combustion process.
The present invention is to utilize the energy of temperature end in combustion process by the mode of low-temperature flue gas reflowed combustion, is realizing burning
While the conservative control of temperature, the heat of temperature end is fully used, reaches the purpose effectively realizing saving fuel.By
Reduction in ignition temperature also inhibits the generation of nitrogen oxides, further uses the mode of fractional combustion, nitrogen oxygen in flue gas
The content of compound can decline further.Therefore, the present invention proposes a kind of burner in order to complete the flue gas of gas fuel combustion
Reflowed combustion and two unique combustion processes of fractional combustion, at the fuel-saving content reducing nitrogen oxides simultaneously, really
Realize the technical goal of the efficient, energy-conservation of combustion apparatus and environmental protection.And through test the most repeatedly and actual application, all achieve aobvious
The effect write, depends on the difference of ignition temperature and technological temperature owing to saving the amount of fuel, and the biggest energy-saving effect of difference is the best,
And amount of nitrogen oxides depends on the height of temperature and the oxygen debt degree of fractional combustion, the applicable cases of the present invention is as follows: use
Time on aluminium melting furnace, ignition temperature can be made to drop to 1100 DEG C from 1850 DEG C, the saving of its energy can reach original 50%,
And amount of nitrogen oxides can be reduced to about 300ppm up and down from 3000ppm accordingly；When using on dry distilling gas heating furnace,
Ignition temperature can be made to drop to 800 DEG C from 1300 DEG C, and the saving of its energy is up to about 30%, and nitrous oxides concentration can be from 2000ppm
Being reduced to about 200ppm up and down, more importantly due to the reduction of ignition temperature, the Pintsch process amount of its gas can drastically subtract
Few, effectively reduce the consumption of distillation process gas.
Obvious, industrial furnace wants meet the requirement of environmental protection and energy conservation object, uses this temperature control, low nitrogen, energy-conservation burning dress
Putting is inevitable choice, because this burner has extremely strong combustion adaptive and the scope of application widely, and achieves work
The low nitrogen burning of industry stove and energy-saving combustion, have the most considerable economic benefit and social benefit.
