What is How does a biogas plant generate electricity??

Organic substrates (maize silage, slurry) ferment in the digester into biogas (approx. 52–55 % CH4); the biogas drives a gas engine that rotates a generator — simultaneously, the engine heat is used for the heating network.

What the AI reads from these values

What the AI reads
  • Methane content (CH4) in the biogas as an indicator of gas quality and calorific value
  • Engine power in kW(el) to monitor the achieved electricity yield
  • Exhaust gas temperature to determine the available thermal energy
  • Operating pressure of the biogas as a measure of plant safety and gas supply
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 identifies the trend before the limit value is reached.

Why this matters

The coupling of electricity generation and heat utilization in the CHP unit minimises entropy losses and maximises the economic yield per cubic metre of biogas. By using the CHP system, a stable base load supply is secured. Efficient waste heat utilization significantly reduces costs for thermal processing. Gas volume (m³/h) · methane content (%) → — kWh/h Calculation path: gas volume × methane content × 9.97 kWh/m³ (methane calorific value)
