This is the tenth Quarterly Technical Report for DOE Cooperative Agreement No: DE-FC26-00NT40753. The goal of the project is to develop cost effective analysis tools and techniques for demonstrating and evaluating low NO{sub x} control strategies and their possible impact on boiler performance for firing US coals. The Electric Power Research Institute (EPRI) is providing cofunding for this program. This program contains multiple tasks and good progress is being made on all fronts. During this quarter, progress was made on the computational simulation of a full-scale boiler with the purpose of understanding the potential impacts of burner operating conditions on soot and NO{sub x} generation. Sulfation tests on both the titania support and vanadia/titania catalysts were completed using BYU's in situ spectroscopy reactor this quarter. These experiments focus on the extent to which vanadia and titania sulfate in an SO{sub 2}-laden, moist environment. Construction of the CCS reactor system is essentially complete and the control hardware and software are largely in place. A large batch of vanadia/titania catalyst in powder form has been prepared for use in poisoning tests. During this quarter, minor modifications were made to the multi-catalyst slipstream reactor and to the control system. The slipstream reactor was …
