Description
<EMI ID=1.1>
<EMI ID=2.1> de soufflage habituelles.
<EMI ID=3.1>
<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
