| Genset working condition: |
|
|
|
| 1. Acceptable working conditions: |
|
|
|
| Ambient temperature: -10ºC~+45ºC (Antifreeze or hot water needed for below -20ºC) |
| Relative humidity:<90%(20ºC), Altitude: ≤500m. |
| 2. Applied gas: Biogas |
|
|
|
| Acceptable fuel gas pressure: 8~20kPa, CH4 content ≥50% |
| Gas low heat value (LHV) ≥23MJ/Nm3. If LHV<23MJ/Nm3, gas engine power output will decrease and electrical efficiency will decrease. Gas doesn't include free condensation water or free materials (the size of impurities should be less than 5μm.) |
| Relative humidity:<90%(20ºC), Altitude: ≤500m. |
| H2S content≤ 200ppm. NH3 content≤ 50ppm. Silicon conent ≤ 5 mg/Nm3 |
|
|
|
| Impurities content≤30mg/Nm3, size≤5μm, Water content≤40g/Nm3, no free water. |
| NOTE: |
|
|
|
| 1. H2S will cause corrosion to engine components. It's better to control it below 130ppm if possible. |
| 2. Silicon can appear in engine lubricant oil. High silicon concentrations in the engine oil can cause heavily wear and tear on engine components. Engine oil must be assessed during CHP operation and oil type must be decided according to such oil assessment. |
