BHKW Fermenter Gasblase festgefroren bei 100% - Ursachen, Diagnose und Loesung
Field report from real operational data: BHKW Fermenter Gasblase festgefroren bei 100% - Ursachen, Diagnose und Lösung
In biogas plants, a stuck gas bubble in the fermenter can quickly lead to production failures and operational disruptions. Our monitoring data shows recurring messages for fermenter R310, where the gas bubble is permanently frozen at 100%.
### Typical Causes of Malfunction
The analysis of our operational data reveals several potential reasons:
1. **Substrate Problems**
- High dry matter content
- Uneven mixing
- Encrustation in the fermenter area
2. **Technical Malfunctions**
- Defective agitators
- Clogged pipelines
- Faulty gas bubble measurement
3. **Microbiological Disruptions**
- Shift in acid-base balance
- Inhibition of bacterial activity
### Diagnosis and Recommended Actions
To identify the cause, we recommend the following steps:
- Immediate visual inspection of the fermenter
- Checking agitators and mixing systems
- Laboratory analysis of the substrate
- Verification of gas bubble sensors
### Concrete Solution Approaches
1. Optimize substrate management
2. Maintain/replace agitators
3. Stabilize microbiology
4. Calibrate sensors
Our data analysis shows that the normal gas bubble position varies between 22.9% and 83.1%. A permanent value of 100% indicates a serious disruption.
