【 摘 要 】

This is the eighteenth Quarterly Technical Report for DOE Cooperative Agreement No: DEFC26-00NT40753. 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 boilers firing US coals. The Electric Power Research Institute (EPRI) is providing co-funding for this program. Safety equipment for ammonia for the SCR slipstream reactor at Plant Gadsden was installed. The slipstream reactor was started and operated for about 1400 hours during the last performance period. Laboratory analysis of exposed catalyst and investigations of the sulfation of fresh catalyst continued at BYU. Thicker end-caps for the ECN probes were designed and fabricated to prevent the warpage and failure that occurred at Gavin with the previous design. A refurbished ECN probe was successfully tested at the University of Utah combustion laboratory. Improvements were implemented to the software that controls the flow of cooling air to the ECN probes.
