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 3 /h. The pressures have been measured with the 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.
