Ash Performance Indices
To evaluate fuel performance, Microbeam developed Coal Quality Management System (CQMS) software. This software calculates advanced indices relating coal characteristics to ash behavior in a coal-fired utility boiler.
Coal Quality Index (CQI) and Plant Performance Index (PPI)
New indices for optimizing boiler performance through fuel blending, additive use, and operational adjustments
For a given fuel, Microbeam can now use its new Coal Quality Index (CQI) to provide information toward determining optimal fuel blending and use of additives for enhanced system thermal and environmental performance. The CQI calculation uses fuel quality information derived from the ASTM analysis for the sample tested combined with Microbeam’s database information to provide a single index value that can be tailored for specific plants..
Additionally, Microbeam also provides Plant Performance Index (PPI) calculations, based on plant operational parameters input and fuel quality. Plant personnel can use this data to optimize boiler operations in order to maintain slag flow, minimize NOx formation, and minimize ash deposition.
