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 1440 kW it
is necessary to have a 17 mbar at the
coupling with the chamber at 0. Should
the combustion chamber be pressurized
at +3 mbar, the required pressure is
17 + 3 = 20 mbar.
