Requirements for fuel gas
In order to ensure its reliable and stable operation of the generator set, the requirements for the natural gas quality is as follows:
——Natural gas should be dehydrated without any water, crude oil & clean oil
——Natural gas pressure 100～400kPa；
——Natural gas temperature -20～40℃；
——Total sulfur content less than 200mg/m3
Note: Gas volume is under standard condition with 100kPa atmosphere, 20℃ambient temperature,30% relative moisture.
Cooling System
2000kW Gas generator set adopts closed circulation flat bed radiator. This radiator owns low consumption and high efficiency characteristics.
