Special notes: The definition of generator power is as follows: Rated Power (PRP): 1. The running time is unlimited every year. 2. In a 250 hours continuous period, the average load rate should not exceed 80% . 3. Under 100% load, the total running hours should be no more than 500 hours in one year period;

Requirements for natural gas:

1.  The methane content should not be lower than 95%.
2.  The gas temperature should be between 0-40 ºC.
3.  No impurity should be in the gas. Water in the gas should be less than 20g/Nm³.
4.  Heat value should be at least 8500kcal/m³, if less than this value, the power of the engine will be declined.
5.  Gas pressure should be 3-100KPa, if the pressure is less than 3KPa, booster fan is necessary, and pressure relief device should be added if the value is higher than 100KPA;  
6.  The gas should be dehydrated and desulfurized. Make sure that there is no liquid in the gas. H₂S<200mg/Nm³
