Description
Summary:•A diagnostic tool to indicate turbine system problems is proposed.•NOx emissions can enhance the data reconciliation process in turbine systems.•NOx emissions measurements and data reconciliation can find turbine system problems. Standard monitoring within a gas-turbine based cogeneration system includes key flow rates, temperatures, pressures and turbine vibration. These standard measurements can be enhanced with continuous emissions monitoring to help pinpoint system problems. A combination of these measurements, a fast NOx prediction model and data reconciliation constitute an improved monitoring and diagnostic tool that can quantitatively predict the existence of turbine problems (for example, damaged combustor nozzles) even when standard turbine monitoring indicates no problems exist.
