【 摘 要 】

This is the eighth 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 NOx control strategies and their possible impact on boiler performance for firing US coals. The Electric Power Research Institute (EPRI) is providing co-funding for this program. This program contains multiple tasks and good progress is being made on all fronts. CFD modeling studies of RRI in a full scale utility boiler have been performed that provide further insight into the NOx reduction process that occurs if the furnace is not adequately staged. In situ reactivity data indicate thus far that titania sulfates under SCR conditions but there is no indication of vanadia sulfation in agreement with some, but not most literature results. Additional analysis and advanced diagnostics are under way to confirm this result and determine its accuracy. Construction of a catalyst characterization reactor system is nearly complete, with a few remaining details discussed in this report. Shakedown testing of the SCR field reactor was completed at the University of Utah pilot-scale coal furnace. The CEM system has been ordered. Talks continued with American Electric Power about hosting a demonstration at their Rockport plant.
