What is gas pressure / inlet pressure?

Minimum gas pressure for engine start: approx. 20 mbar; too low a gas pressure is a common cause of start failures — the gas pressure sensor in the PLC monitors and secures the system.

What the AI reads from these values

What the AI reads
  • Detection of minimum gas pressure (approx. 20 mbar) to prevent start failures
  • Monitoring of the inlet pressure to ensure a constant fuel supply
  • Identification of leaks or blockages in the gas network through deviations from the setpoint
  • Ensuring plant safety through automatic shutdown at critical pressure values
Scenario

Monitored: 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

A stable gas pressure prevents downtime due to start failures and protects the engine components from incomplete combustion. Precise monitoring of the inlet pressure enables proactive maintenance of the supply lines. This minimizes the risk of emergency shutdowns and ensures the continuous output of the CHP unit. Gas volume (m³/h) · methane content (%) → — kWh/h calculation method: gas volume × methane content × 9.97 kWh/m³ (calorific value of methane)
