Burner description
Gas pressure on the basis of the
maximum output developed by
the burner is given by the curves
in Fig. 8.
It represents the pressure drop
in the combustion head.
Natural gas G 20 - Net calorific
3
value = 10 kWh/Nm
The curves were taken in the fol-
lowing conditions:
• pressure measured at the test
point on the pressure switch
downstream from the gas but-
terfly valve;
• combustion chamber at 0
mbar;
KW
• burner working at full output.
The pressure drop of the com-
pletely open butterfly valve is
given in Fig. 9.
