Product Description
37.5KVA 30KW Biogas Generator Set

Genset working condition:
Altitude: 500m above sea level
Ambient temperature: 0ºC ~ + 40ºC (The temperature lower than 0ºC will need oil heater and water heater)
Required Gas Pressure: 7-12kPA
Biogas Requirement: CH4 content≥55%, Gas heat value≥5500kcal/Nm3 (23MJ/Nm3 ).
If use low heat value gas for fuel Heat value<5500kcal/Nm3, it will lower the power efficiency.
Gas does not include free water or free materials (the size of impurities should be less than 5μm.)
H2S content≤100mg/Nm3
NH3 content≤20mg/Nm3
Impurities content≤30mg/Nm3;size≤5μm
Water content≤40g/Nm3, no free water.
