250KW Natural Gas Generator / Gas Generator Set / Gas power generator
Genset working condition:
lAcceptable working conditions:
Ambient temperature : -10°C~+40°C
(antifreeze and water heater needed for below 0°C)
Relative humidity:< 90% (20°C)
Altitude:≤ 500m
l Normal working conditions:
Genset can run at rated power on the conditions:
Atmospheric Pressure: 100kPa, Ambient Temp: 20°C, Relative Humidity: 30%.
lApplied gas:
Natural Gas, Biogas, LPG, Landfill gas, Oil gas, Syngas, Coal mine gas
Acceptable fuel gas pressure: 8~12kPa
CH4 content: for natural gas≥85% CH4 content: for biogas≥55%
