Is the SmartCEMS® PEMS also valid during start-up and shutdown of the unit?

The model is valid during normal operation of the turbine or boiler, during start-ups and during shutdowns, as well as, trips, interruptions, etc. Each of the deployed SmartCEMS® PEMS to date has been certified to continuously monitor emissions during all normal operations including startups and shutdowns. The accuracy of the model during startups and shutdowns is demonstrated, however, the accuracy is improved as more transition data is included in the historical training dataset. It is important to include startup and shutdown data along with other data from transient operations in the initial historical training dataset to ensure accuracy of predictions for these operating conditions.
