PRESSURE CURVES/GAS DELIVERY
These curves show the gas pressure, in millibars, (at points Pi and Pt along the gas train)
necessary to produce a given delivery in m
burner working and with a pressure of 0 mbar in the combustion chamber. If the chamber
is pressurized, the gas pressure necessary will be that given in the diagram plus that in the
combustion chamber.
