My name is Katherine Hedrick, and I joined the Bhattacharyya group at WVU in July of 2017 to pursue a Ph.D. in chemical engineering. My research is focused on the use of first-principles modeling for equipment health monitoring of supercritical pulverized coal-fired power plants as part of a research collaboration with the National Energy Technology Laboratory.

Modeling and Monitoring of a Supercritical Pulverized Coal-Fired Boiler
My research is focused on investigating the impact of load-following on the health of supercritical pulverized coal-fired boilers. To accomplish this, a dynamic, first-principles-based boiler model was developed. the high-fidelity model includes calculation of the thermal profiles of the tubes within the boiler as well as the steam headers of the boiler. These thermal profiles allow for the calculation of the stresses experienced by the boiler components, which in turn can be used to determine the damage done to the boiler while cycling in response to changes in power demand.
