Combustion chamber pressure
The combustion chamber pressure is the same as for natural
gas.
2.7
Gas pressure and output
Tab. A indicates the minimum pressure drops along the gas sup-
ply line, depending on the maximum burner output.

WARNING
For pressure levels different from those indicated
above, please contact the Technical Office.
Pressure:
measured at the coupling with combu-
stion chamber at 0 mbar. If the combu-
stion chamber is pressurized, the
required gas-pressure is that shown on
the diagram plus the pressurization va-
lue.
Example: in order to develop 350 kW it is
necessary to have a 14 mbar at the cou-
pling with the chamber at 0. Should the
combustion chamber be pressurized at
+3 mbar, the required pressure is
14 + 3 = 17 mbar.
Output:
maximum output obtainable with:
–
gas with a net heat value of 22.200
kcal/m3;
–
gas ring set as indicated in the
Gas 4, Gas 4/2 and Gas 4 P/M tech-
nical instructions under the para-
graph “Combustion - Head Setting”.
