What is Why does a biogas plant need a gas tank??

The gas storage tank decouples continuous biogas production from discontinuous CHP unit operation; at 40–80 % fill level, the CHP unit operates optimally — Underfilling leads to gas shortage and engine shutdown, overfilling leads to pressure valve opening.

What the AI reads from these values

What the AI reads
  • Current fill level to avoid gas shortage at low levels
  • Pressure stability to ensure a constant calorific value in the CHP unit
  • Overfill detection to prevent the opening of safety valves
  • Calculation of operating time based on the current gas volume
Scenario

Monitoring: continuous

The scenario: if the methane content drops slowly, the engine begins to knock without an alarm occurring, leading to power reduction and wear. The AI: detects the quality trend early and reports it before the knocking causes damage. It detects the trend before the limit value is reached.

Why this matters

An optimal fill level of 40–80 % prevents engine shutdowns and minimises mechanical stress caused by pressure fluctuations. The decoupling of production from consumption ensures a constant gas supply for the engine. This reduces downtime and protects the components of the CHP unit from unstable gas phases. Gas volume (m³/h) · methane content (%) → — kWh/h Calculation method: gas volume × methane content × 9.97 kWh/m³ (methane calorific value)
