ATTENTION: the gas rate value is quoted on the x-axis, the related network pressure is quoted on the y-axis
(pressure value in the combustion chamber is not included). To know the minimum pressure at the gas train inlet,
necessary to get the requested gas rate, add the pressure value in the combustion chamber to the value read on
the y-axis.
The values in the diagrams refer to natural gas with a calorific value of 8125 kcal/Stm
3
(15°C, 1013 mbar) and a density of
0.714 kg/Stm
3
.
The values in the diagrams refer to GPL with a calorific value of 22300 kcal/Stm
3
(15°C, 1013 mbar) and a density of 2.14 kg/
Stm
3
. When the calorific value and the density change, the pressure values should be adjusted accordingly.
