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 com-
bustion chamber. If the chamber is pressurized, the gas pressure necessary will be that given in the diagram plus that in
the combustion chamber.
BASIC GAS TRAIN
