(1) The methane content should not be lower than 55%.
(2) The Biogas temperature should be between 0-601D.
(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 5500kcal/m3, if less than this value, the power of the engine will be declined.
