Description/Abstract	This project by the Energy and Environmental Research Center (EERC) focuses on the issues of entrained-ash formation and slagging for low-NO{sub x} combustion systems in general. Time-resolved combustion tests under conventional and low-NO{sub x} conditions have been conducted to note particle-size formation and slagging deposition. Results will be used to support demonstration projects at the utility boiler scale. The results from this work are yielding an increased understanding of the mechanisms of ash formation during low-NO{sub x} combustion along with methods for enhancing heat transfer and fly ash collectibility. Specific objectives of this research project include (1) determining whether initial char and ash generated under low-NO{sub x} conditions have greater tendencies for slagging than conventionally generated ash and (2) determining the differences, if any, between particle size and composition for entrained ash generated under low-NO{sub x} and conventional combustion conditions. Progress on this sub-task is presented.
