Book Description
This is the twentieth 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-NO(subscript 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. At the beginning of this quarter, the corrosion probes were removed from Gavin Station. Data analysis and preparation of the final report continued this quarter. This quarterly report includes further results from the BYU catalyst characterization lab and the in-situ FTIR lab, and includes the first results from tests run on samples cut from the commercial plate catalysts. The SCR slipstream reactor at Plant Gadsden was removed from the plant, where the total exposure time on flue gas was 350 hours. A computational framework for SCR deactivation was added to the SCR model.

Book Description
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.

Book Description
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(subscript 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 O2 and NO(subscript x) made by the CEMs corresponded to values measured by the plant at the economizer outlet. Excellent NO(subscript x) reduction was observed in preliminary tests of the reactor. Some operational problems were noted and these will be addressed next quarter.

Book Description
Available Information on control of NOx emissions from stationary combustion sources has been compiled to assist new source permitting activities by regulatory agencies. The sources covered are combustion turbines, Internal combustion engines, non-utility boilers and heaters, and waste Incinerators. The report discusses the background of NO, formation in the combustion process, major NO sources, and processes for NOx control. The current status of NO control technology Is discussed and applications to meet permitting requirements Is detailed. Permitted NOx emission levels are summarized by combustion source, fuel type and control technology. Documentation includes references and contacts for further Information.
