Description
Technical field
This utility model relates to a kind of igniter field, particularly relates to a kind of pure oxygen steady burning burner and surely fires dress
Put.
Background technology
Existing burner, is usually by the oxygen hose lateral surface by burner, piggybacking two stage burner brace rod,
With endless belt 30～45° angle, oxygen being injected burner centre cylinder, oxygen can be heated, and (secondary wind, First air all can add
Hot oxygen), cooling burner wall simultaneously, it is ensured that the breeze airflow that classification is lighted safety in internal combustion burner is lighted.But
Existing burner comes with some shortcomings, and due to oxygen hose oblique insertion in the inner tube of housing, therefore can stream field impact strengthen,
Thus cause jet-impingement uneven, and not only cause the combustion instability of coal dust, and relatively big to the erosion of wall of burner, make
The service life becoming burner reduces.
Because above-mentioned defect, the design people's the most in addition research and innovation, to founding a kind of pure oxygen steady burning burner
And smooth combustion apparatus so that it is have more the value in industry.
Utility model content
The purpose of this utility model is to provide a kind of pure oxygen steady burning burner and smooth combustion apparatus thereof, to solve above-mentioned background
The problem proposed in technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of pure oxygen steady burning burner, including shell, is provided with demarcation strip, described demarcation strip below the elbow of described shell
On be provided with perforate.
Further, the thickness of the demarcation strip of described burner is 30mm.
Further, the material of the demarcation strip of described burner is abrasion-resistant stee.
This utility model additionally provides the smooth combustion apparatus of a kind of pure oxygen steady burning burner, including housing, burner, oxygen spray
Rifle and steady combustion oxygen rifle, described burner is arranged in housing, and described oxygen lance is arranged in described burner, and described oxygen sprays
The end of rifle is passed described burner by the knee of described burner, and described oxygen lance is inserted at the knee of described burner
Entering in burner, described steady combustion oxygen rifle is arranged on the outside of described burner top, and described burner is above-mentioned burner.
Further, described oxygen lance is provided with arranged side by side two oxygen lance nozzle, and oxygen lance spraying at burner nozzle
Mouth is arranged on the sidewall of housing, and housing is arranged in secondary air box.
Further, described steady combustion oxygen rifle is being provided with two oxygen jets arranged side by side near burner top nozzle.
By such scheme, this utility model at least has the advantage that 1, by oxygen lance, by oxygen with certain angle
Degree sprays into burner hearth, allows oxygen rapidly enter pulverized coal flame, is conducive to burning；2, burner is provided with demarcation strip with holes, beneficially oxygen
Gas is even into burner centre；3, burner, oxygen lance, steady combustion oxygen rifle are arranged in secondary air box, it is possible to use one
Secondary wind heating oxygen, is conducive to burning, reduces burner wall temperature, beneficially safe operation simultaneously.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed
Describe in detail bright as after.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of the smooth combustion apparatus of a kind of pure oxygen steady burning burner of the present utility model；
Fig. 2 be the smooth combustion apparatus of a kind of pure oxygen steady burning burner shown in Fig. 1 side schematic view.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Seeing Fig. 1 and Fig. 2, a kind of pure oxygen steady burning burner described in this utility model one preferred embodiment, at burner 2
Elbow below the thick demarcation strip 5 of 30mm is set, the material of demarcation strip 5 is abrasion-resistant stee；It is provided with out in this demarcation strip 5
Hole, oxygen sprays into the center of burner 2 by perforate.
See Fig. 1 and Fig. 2, a kind of pure oxygen steady burning burner described in this utility model one preferred embodiment surely fire dress
Putting, including burner 2, oxygen lance 3 and steady combustion oxygen rifle 4, oxygen lance 3 is arranged on the inside of burner 2, oxygen lance 3
End is passed burner 2 by the knee of burner 2, and this oxygen lance 3 is separated into two oxygen lance sprayings at the nozzle of burner 2
Mouth, oxygen is sprayed into burner hearth by oxygen jet at a certain angle, converges at spout about the 200mm of burner 2 with pulverized coal flame
Poly-.
Steady combustion oxygen rifle 4 is arranged on the outside at burner 2 top, and this oxygen rifle, near burner 2 top nozzle, separates
It is two oxygen jets, and the oxygen lance nozzle of both sides is arranged on the sidewall of housing.Oxygen is sprayed by oxygen jet at a certain angle
Enter burner hearth, converge at burner nozzle about 200mm with pulverized coal flame.
Operation principle of the present utility model is as follows:
At coal burner fire inspection signal less than the 20% of former positive normalizing inspection signal intensity, (this value can be according to different pots
The characteristic of stove adjusts and sets), by corresponding control system, open the electrically operated valve of above-mentioned oxygen rifle, allow oxygen the most quickly enter
Enter the coal air mixture within burner 2, burner 200mm outside the pulverized coal flame and burner top spout of fire side left
Right pulverized coal flame, the most combustion-supporting, reach the purpose that this angle coal burner surely fires.
Burner 2, oxygen lance 3, steady combustion oxygen rifle 4 are arranged in housing 1 by this utility model, by oxygen lance 3, and will
Oxygen sprays into burner hearth at a certain angle, allows oxygen rapidly enter pulverized coal flame, is conducive to burning；Burner 2 is provided with holes point
