CH4 content: for natural gas≥85% CH4 ,content:for biogas≥40%
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.
Gas doesn’t include free water or free materials (the size of impurities should be less than 5μm.)
