Genset working condition:

Acceptable working conditions:

Ambient temperature : -10°C~+40°C (antifreeze or preheater needed for below 0°C)

Relative humidity:<90%(20°C)

Altitude:≤1000m

Normal working conditions:

Genset can run at rated power on the conditions:

Atmospheric Pressure: 100kPa, Ambient Temp: 20°C, Relative Humidity: 30%.

Applied gas:

Natural Gas, Biogas, LPG, Landfill gas, Oil field gas, Syngas, Coal bed gas etc

Acceptable fuel gas pressure: 5~50kPa

CH4 content: for natural gas≥85% CH4 content:for biogas≥55%

Gas heat value≥5500kcal/Nm3 (23MJ/Nm3 ). Genset output power will increase as the gas heat value increase, if use low heat value gas for fuel (Heat value<5500kcal/Nm3, it will decrease the power efficiency.

Gas doesn’t include free water or free materials (the size of impurities should be less than 5μm.)

H2S content≤20mg/Nm3

NH3 content≤20mg/Nm3

Impurities content≤30mg/Nm3;size≤5μm

Water content≤40g/Nm3, no free water.
