These curves show the gas pressure in millibar (at various points along the gas train) necessary to produce
a given flow rate (cu m/h). The pressures have been measured with the burner working, with combustion
chamber pressure at 0 millibar. If the chamber is pressurized, then the gas pressure necessary will be that
given in the graph plus that in the combustion chamber.
