Medium to high velocity, capacity depending<br />
on the diameter<br />
In the case of continuous control, usage in<br />
the lower capacity range (≥ 40%) is restricted,<br />
depending on the burner<br />
The connection rating of the burners is<br />
chiefl y dependent on the capacity of the<br />
burner chamber.<br />
The connection rating of the burners is<br />
chiefl y dependent on the capacity of the<br />
burner chamber, usually < 2.5 W/cm². A<br />
draught blocker must be fi tted on the fl ue<br />
gas side.<br />
Protection of the fl ame from cooling is ensured<br />
by using a protective fl ame tube FPT<br />
(recommended for fl ow velocity of<br />
> 15 m/s)<br />
* See burner with attachment tube or burner quarl type.<br />
1) When using the burners in radiant tubes or in small combustion chambers, a trial under operating conditions is recommended. The burners must be<br />
secured gas-tight to the furnace or burner quarl by the furnace fl ange, so that a backfl ow of hot fl ue gases is avoided.<br />
2) The outlet diameter of the radiant tube must be reduced to the point where a pressure loss of approx. 10 mbar occurs at max. burner capacity.<br />
3) Only where the furnace temperature is < 600°C.<br />
4) For optimal operation, the burner quarl and the fl ame shapes are combined according to the fi eld of application (see Burners in burner quarls).<br />
