Conditions for Using
1. The temperature of the gas should not surpass 40℃ when the distance between the gas and the pressure regulating valve for air inflow is 1m.
2. This biogas generator set can sustain pressure ranges from 3kPa～10kPa and the fluctuated frequency should not surpass 1kPa/min.
3. The content of the methane in the biogas should not be lower than 45% and its fluctuated frequency should not surpass2%/min.
4. The content of H2S should not surpass 200mg/Nm3 and the content of NH3 should not surpass 20mg/Nm3.
5. The granularity of the impurity should not surpass 5μm and the content of the impurity should not surpass 30mg/Nm3.
6. The content of water in biogas used in this biogas generator set should not surpass 40g/Nm3.
7. Low density biogas generator should be used for biogas with methane of about 30%~45%.
For those gases which cannot reach the conditions above, this biogas generator set should be specially allocated after evaluation according to the specified composition, pressure, temperature, etc. provided.
