Combustion chamber pressure

The combustion chamber pressure is the same as for natural
gas.

required gas-pressure is that shown on
the diagram plus the pressurization va-

Example: in order to develop 240 kW it is
necessary to have a 11 mbar at the cou-
pling with the chamber at 0. Should the
combustion chamber be pressurized at
+3 mbar, the required pressure is
11 + 3 = 14 mbar.
