SPECIFICATIONS
Note: all gas flow rates (Stm
3
/h) are referred to standard gas conditions: 1013 mbar pressure, 15 °C temperature.
Flow rates are referred to G20 natural gas (nett calorific value: 34.02 MJ/Stm
3
), if G25 is used (n.c.v.: 29.25 MJ/Stm
3
), flow rates
must be multiplied by 1.16 factor.
* Minimum pressure to get the maximum rate with any value of back pressure in combustion chamber. The burner operates cor-
rectly also with lower pressures but these must guarantee the needed rate.
