Technical field
The present invention relates to the burner of the heat utilization equipment of industrial furnace class, the pot particularly suitable for burn gas fuel
A kind of smoke backflow that the industrial furnaces such as stove, heating furnace, hot-blast stove, metal smelting-furnace, rotary kiln, tunnel cave, shuttle kiln use
The burner of indole energy low with the temperature control of Staged Premixed Combustion.
Background technology
Currently, industrial furnace from energy-conservation with considering in environmental protection, it is desirable to burner is in different fuel and the different coal gas of burning
Lower while obtain efficiently controllable completely burned, also requirement can effectively reduce the nitrogen oxides in combustion process（NOx）Life
Cheng Liang, to be finally reached efficient, energy-saving and environmental protection purposes.Therefore, except necessary in the structure design of industrial furnace burner
Realize that Quick uniform mixing and stable burning are outer, should be able to also adapt to different combustion gas kinds make it have the regulation of combustion process can
The feature of control.This just will not only be related to the structure of related burner and respective combustion chamber and mutual reasonable disposition, and more
It is important that the design of this body structure of burner, so as to produce corresponding technique effect.Making a general survey of current various industrial furnaces makes
Normal burner, hence it is evident that the various problems in structure because of caused by design concept be present, this certainly will just cause coal
Uneven and incomplete combustion is mixed between gas and air.Especially a kind of burning is ignored for a long time with phenomenon of Heat by people, this
Exactly turned a blind eye to for energy loss caused by the difference between ignition temperature and temperature in use（Energy level loss wouldn't examine
Consider）, the method that increase excess air coefficient is usually taken deacclimatizes the requirement of technological temperature, and this is actually a kind of temperature end energy
The invisible loss of amount, this is also a major issue of people's institute's long-standing neglect in the application of energy step.For exhaust gas temperature 200
Low-grade energy below DEG C has more not to be given up, goes to be applied using larger investment, and to 200 DEG C of high temperature section and its above temperature
Difference is but turned a blind eye to, and prevents energy from rationally utilizing, then how while the reasonable control of ignition temperature is realized, by high temperature
The heat at end is fully used, and reaches and saves fuel, purpose that is cost-effective and suppressing NO_x formation, is current urgent
Solve the problems, such as.
The content of the invention
For the above situation, to overcome prior art defect, the purpose of the present invention is exactly to propose a kind of smoke backflow with dividing
The burner of the low indole energy of temperature control of level premixed combustion, can efficiently accomplish direct current or cyclone classification premix and the combustion of air-flow

While the reasonable control of temperature, the heat of temperature end is fully used, reaches the purpose effectively realized and save fuel.By
The generation of nitrogen oxides, further by the way of fractional combustion, nitrogen oxygen in flue gas are also inhibits in the reduction of ignition temperature
The content of compound can further decline.Therefore, the present invention proposes a kind of burner to complete the flue gas of gas fuel combustion
Reflowed combustion and two unique combustion processes of fractional combustion, fuel-saving while reduce the content of nitrogen oxides, really
Realize the efficient of combustion apparatus, energy-conservation and the technical goal of environmental protection.And through multiple test and practical application repeatedly, achieve aobvious
The effect of work, because the amount for saving fuel depends on ignition temperature and the difference of technological temperature, the bigger energy-saving effect of difference is better,
And amount of nitrogen oxides depends on the height of temperature and the oxygen debt degree of fractional combustion, applicable cases of the invention are as follows：With
When on to 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 corresponding amount of nitrogen oxides can be reduced to 300ppm or so from above and below 3000ppm；When using on destructive distillation gas heating furnace,
Ignition temperature can be made to drop to 800 DEG C from 1300 DEG C, up to 30% or so, nitrous oxides concentration can be from 2000ppm for the saving of its energy
200ppm or so is reduced to up and down, more important is the reduction due to ignition temperature, the Pintsch process amount of its gas can drastically subtract
It is few, effectively reduce the dosage of distillation process gas.
Obvious, industrial furnace wants meet the requirement of environmental protection and energy conservation object, is filled using the burning of this temperature control, low nitrogen, energy-conservation
It is inevitable choice to put, because the burner has extremely strong combustion adaptive and the extensive scope of application, and realizes work
The low nitrogen burning and energy-saving combustion of industry stove, there are more considerable economic benefit and social benefit.
