What is What are the benefits of exhaust heat recovery??

Without WHR, the exhaust heat (380–450 °C at the turbo outlet) leaves the plant unused; with WHR, the overall efficiency increases to over 85 % — Investment in WHR pays for itself through saved heating energy.

What the AI reads from these values

What the AI reads
  • Exhaust gas temperature at the outlet as an indicator for the available heat potential
  • Difference between exhaust gas temperature and flow_in temperature to calculate the heat transfer efficiency
  • Monitoring of heat exchanger efficiency to prevent material fatigue caused by corrosion
  • Analysis of the thermal efficiency to determine the payback period of the WHR component
Scenario

Monitored: continuous

The scenario: if the temperature difference decreases, the CHP unit extracts less heat, resulting in lower overall efficiency and cogeneration benefit. The AI: detects the shrinking temperature difference early, before the amount of heat drops significantly. It identifies the trend before the limit value is reached.

Why this matters

The use of exhaust heat increases the overall efficiency to over 85 % and directly reduces costs for external heating energy. By coupling heat and electricity, the energy potential of the CHP unit is maximised. The invested WHR component pays for itself through significant savings in primary energy in the heating process. Heating water flow rate (m³/h) · flow_in/flow_out temperature difference (K) → — kW thermal Calculation path: flow rate × temperature difference × 1.16 kWh/(m³·K) (water)
