NO{sub x} CONTROL OPTIONS AND INTEGRATION FOR US COAL FIRED BOILERS
This is the eleventh 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 boilers 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. During this quarter, FTIR experiments for SCR catalyst sulfation were finished at BYU and indicated no vanadium/vanadyl sulfate formation at reactor conditions. Poisoned catalysts were prepared and tested in the CCS. Poisoning with sodium produced a noticeable drop in activity, which was larger at higher space velocity. A computer code was written at BYU to predict conversion along a cylindrical monolithic reactor. This code may be useful for monolith samples that will be tested in the laboratory. Shakedown of the slipstream reactor was completed at AEP's Rockport plant. Ammonia was connected to the reactor. The measurement of O{sub 2} and NO{sub x} made by the CEMs corresponded to values measured by the plant at the economizer outlet. Excellent NO{sub x} reduction was observed in preliminary tests of the reactor. Some operational problems were noted and these will be addressed next quarter.
