Note1:
all gas flow rates are referred to Stm
3
/h (1013 mbar absolute pressure, 15 °C temperature) and are valid for G20 natural gas
(nett calorific value H
i
= 34.02 MJ/Stm
3
).
Note2: Maximum gas pressure = 500mbar (with Siemens VGD.. / Dungs MBC..gas valves)
Minimum gas pressure = see gas curves.
