Product Description

Genset working condition:

Acceptable working conditions:

Ambient temperature : 0℃～+40℃, ambient below 0℃ need special design.

(antifreeze or hot water needed for below -20℃)

Relative humidity：＜90%（20℃）

Altitude:≤1000m

Normal working conditions:

Genset can run at rated power on the conditions:

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

Applicable gas:

Natural Gas, Biogas, LPG, Coal-bed Gas

Within one meter before pressure regulating valve:

Gas temperature≤40℃

Acceptable natural gas pipeline pressure: 2~35kPa (above need more valves), change ratio≤1kPa/min

CH₄ volume content ≥70%

For biogas:

Acceptable biogas pipeline pressure: 2~10kPa (above need more valves), change ratio≤1kPa/min

CH₄ volume content≥30%, change ratio≤2% ∕ min

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 lower the power efficiency.

H₂S content≤200mg/Nm³

NH₃ content≤20mg/Nm³

Impurities content≤30mg/Nm³；size≤5μm

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