What is How much methane does the CHP unit need at minimum??

Optimal biogas contains 52–55 % CH4; if the methane content falls below 48 %, power loss and unstable operation occur — the substrate feeding of the biogas plant indirectly controls the gas quality.

What the AI reads from these values

What the AI reads
  • Current CH4 percentage for monitoring gas quality
  • Deviation from the setpoint (52-55 %) as an indicator for substrate problems
  • Calculation of the energetic efficiency based on the pure methane content
  • Early warning of instabilities in engine operation with falling CH4 values
Scenario

Monitored: continuous

The scenario: If the methane level 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 identifies the trend before the limit value is reached.

Why this matters

A stable methane content ensures the target output of the CHP unit and prevents costly downtime caused by unstable combustion conditions. Monitoring enables precise control of the biogas plant. Only in this way can a constant energy feed value for the operation of the CHP unit be guaranteed. Gas volume (m³/h) · methane content (%) → — kWh/h calculation method: gas volume × methane proportion × 9.97 kWh/m³ (methane calorific value)
