NOx Control Options and Integration for US Coal Fired Boilers Quarterly Progress Report: July-September 2002
Description: This is the ninth 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 cofunding for this program. This program contains multiple tasks and good progress is being made on all fronts. Various subsystems of BYU's Catalyst Characterization System (CCS) were upgraded this quarter. Work on the CCS hardware and software will continue in the coming quarter. A preliminary test matrix of poisoning experiments in the CCS has been drafted that will explore the effects of at least three poisons: sodium, potassium and calcium. During this quarter, we attempted to resolve discrepancies in previous in situ measurements of catalyst sulfation. Modifications were made to the XPS analysis procedure that allowed analyses of uncrushed samples. Although the XPS and FTIR results are now more consistent in that both indicate that the surface is sulfating (unlike the results reported last quarter), they disagree with respect to which species sulfates. The CEM system for the multi-catalyst slipstream reactor arrived this quarter. Minor modifications to the reactor and control system were completed. The reactor will be shipped to AEP Rockport plant next quarter for shakedown and installation. In a parallel effort, we have proposed to make mercury oxidation measurements across the catalysts at the start of the field test. Pending approval from DOE, we will begin the mercury measurements next quarter.
