 <EMI ID=4.1> 

  
tion est décrit en se referont au dessin annexe, 

  
 <EMI ID=5.1> 

  
2,2 mm de diamètre qui s'épanouit vers l'amont en un conduit

  
 <EMI ID=6.1>  conduit (7) d'alimentation a. la chambre (9) destinée à l'alimentation de la flamme auxiliaire en mélange comburant combustible.

  
 <EMI ID=7.1> 

  
 <EMI ID=8.1> 

  
et dans le conduit, annulaire (5) par l'intermédiaire des passages (8).

  
Un exemple des débits possibles avec ce brûleur correspondant aux vitesses moyennes de sorties suivantes :

  
 <EMI ID=9.1> 

  
augmentée)

  
 <EMI ID=10.1> 

  
on voit que la vitesse de la flamme principale est considérablement accrue par rapport aux vitesses habituellement possibles sans soufflage.

  
 <EMI ID=11.1> 

  
"tendue", c'est-à-dire ayant un panache très long (80 mm)

  
par rapport à son diamètre.

  
De plus, grâce à la.,'protection des gaz brûles, la flamme principale garde une température pratique de combustion plus élevée et pour un débit calorifique de 520 mth/h on a

  
 <EMI ID=12.1> 

  
à 2 600[deg.] K.

  
Le brûleur décrit précédemment comporte un trou central de 0,5 mm de diamètre, bien entendu, il s'agit d'un exemple et, on peut utiliser toutes les possibilités entre

  
0,3 et 3 mm adaptées aux combustibles envisagés .

  
Les gaz combustibles utilisables avec ce type d'appareil sont essentiellement le propane, les gaz naturels

  
à. base de méthane, le gaz de ville ; on peut également utiliser



   <EMI ID = 1.1>
 

  
 <EMI ID = 2.1> usual blowing.

  
 <EMI ID = 3.1>

  
 <EMI ID = 4.1>

  
tion is described in reference to the accompanying drawing,

  
 <EMI ID = 5.1>

  
2.2 mm in diameter which blossoms upstream in a duct

  
 <EMI ID = 6.1> power supply conduit (7) a. the chamber (9) intended for supplying the auxiliary flame with a combustible oxidant mixture.

  
 <EMI ID = 7.1>

  
 <EMI ID = 8.1>

  
and in the duct, annular (5) via the passages (8).

  
An example of the flow rates possible with this burner corresponding to the following average output speeds:

  
 <EMI ID = 9.1>

  
increased)

  
 <EMI ID = 10.1>

  
it can be seen that the speed of the main flame is considerably increased compared to the speeds usually possible without blowing.

  
 <EMI ID = 11.1>

  
"stretched", that is to say having a very long plume (80 mm)

  
relative to its diameter.

  
In addition, thanks to the protection of the burnt gases, the main flame keeps a practical higher combustion temperature and for a heat output of 520 mth / h we have

  
 <EMI ID = 12.1>

  
at 2,600 [deg.] K.

  
The burner described above has a central hole of 0.5 mm in diameter, of course, this is an example and, one can use all the possibilities between

  
0.3 and 3 mm suitable for the fuels considered.

  
The combustible gases that can be used with this type of device are essentially propane, natural gases

  
at. methane base, town gas; we can also use
