Is the SmartCEM 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 SmartCEM PEMS to date has been certified to continously 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. QUESTION: What other uses could SmartCEM PEMS be applied to? Can the system be used to model turbine combustion efficiency? Can the system be used to provide input for scheduling of maintenance activity? ANSWER: The model was developed for the purpose of providing operators with real-time feedback as to a
