Description
Technical field
The utility model is related to a kind of burner, especially a kind of low nitrogen oxide burner mixing chamber.
Background technology
Low NOxBurner and low nitrogen oxide burner refer to NO in fuel combustion processxThe low burner of discharge capacity, is adopted
With low NOxBurner can reduce the discharge of nitrogen oxides in combustion process.
Generated nitrogen oxide is mainly NO and NO in combustion2, usually both nitrogen oxides are led to
Referred to as nitrogen oxides NOx.Abundant experimental results show that the nitrogen oxides of burner discharge is mainly NO, averagely account for about 95%,
And NO2Only account for 5% or so.
The NO that general fuel combustion is generated is essentially from two aspects：First, nitrogen in burning air (combustion air) used
Oxidation；Second is that institute's nitrogenate thermally decomposes reoxidize in combustion in fuel.In most of burners, Qian Zheshi
The main source of NO, such NO is known as " thermal response NO " by us, and the latter is referred to as " fuel NO ", is in addition also had " wink sends out NO ".
Utility model content
The purpose of this utility model is to provide a kind of low nitrogen oxide burner mixing chamber, and manufacture craft is simple, manufacture
At low cost, combustion gas, air mixing are abundant, and discharged nitrous oxides are low.
To achieve the above object, the utility model takes following technical scheme：
A kind of low nitrogen oxide burner mixing chamber, it includes mixing chamber outer barrel and the connection that is connect with the mixing chamber outer barrel
Flange, the mixing chamber outer barrel air duct coherent with formation inside the connecting flange, the air duct end and the connection method
Blue air interface connection；It is equipped with fuel chamber's outer barrel in the air duct, fuel chamber's inner cylinder, the sky are equipped in fuel chamber's outer barrel
The axial direction in gas channel, fuel chamber's outer barrel and fuel chamber's inner cylinder is parallel；Combustion gas is formed between fuel chamber's outer barrel and fuel chamber's inner cylinder
Room, fuel chamber's outer barrel surface are equipped with the through-hole being evenly distributed；Fuel chamber's outer barrel bottom is radially equipped with to be connected with the fuel chamber
Logical connecting tube, the connecting tube are connect with the combustion gas connector of mixing chamber outer barrel.
Further, the mixing chamber outer barrel is equipped with the blade of annular arrangement with the junction of the connecting flange, adjacent
Air intake passage is formed between blade.
Further, the direction of the air intake passage and the direction of the air duct are at an acute angle.
The utility model has the beneficial effects that：The utility model low nitrogen oxide burner mixing chamber, manufacture craft letter
Single, manufacturing cost is low, and combustion gas, air mixing are abundant, and discharged nitrous oxides are low.

The combustion gas connector 10 of outdoor cylinder 1 connects.
Further, in order to improve the mixed effect of air and combustion gas, the company of the mixing chamber outer barrel 1 and the connecting flange 2
Blade 11 of the place equipped with annular arrangement is connect, air intake passage is formed between adjacent blade 11, the direction of the air intake passage and the air
The direction in channel 3 is at an acute angle.The air inlet of rotation is formed by blade 11, the combustion gas mixing ejected with fuel chamber 7 is sent into combustion
End burning before burner.
The utility model low nitrogen oxide burner mixing chamber, manufacture craft is simple, and manufacturing cost is low, combustion gas, air
Mixing is abundant, and discharged nitrous oxides are low.
Above-described embodiment is merely exemplary to illustrate the principle and effect of the utility model, new not for this practicality is limited
Type.The utility model can be improved there are many more aspect under the premise of without prejudice to overall thought, any to be familiar with this technology
Personage can all be carried out modifications and changes to above-described embodiment under the spirit and scope without prejudice to the utility model.Therefore, it lifts
All those of ordinary skill in the art are complete in the revealed spirit without departing from the utility model and institute under technological thought
At all equivalent modifications or change, should be covered by the claim of the utility model.
