What are the accuracy and reliability levels achieved by SmartCEMS®?

The accuracy of the system is entirely dependent on the quality of the training data set including the emission testing data and the site configuration of the SmartCEMS®. The accuracies achieved under the demonstration on gas turbines and boilers to date have been comparable to a CEMS, achieving better than 10% relative accuracy even at very low levels of NOx (less than 10 ppmv).

 

SmartCEMS® has consistently met the EPA requirement of less than 7.5% relative accuracy for NOx compliance under 40 CFR Part 75. In many cases, SmartCEM® can achieve accuracy levels less than 5% and maintain this level of accuracy for many years running the same model. SmartCEMS® reliability approaches 100% in our installations, typically better than the majority of CEMS installed to date.
