NOx CONTROL OPTIONS AND INTEGRATION FOR US COAL FIRED BOILERS

PDF Version Also Available for Download.

Description

This is the seventh 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. A series of field tests for RRI at the Ameren Sioux Unit No.1 have demonstrated that RRI can provide up to 30% NOx reduction over the use of ... continued below

Description

This is the seventh 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. A series of field tests for RRI at the Ameren Sioux Unit No.1 have demonstrated that RRI can provide up to 30% NOx reduction over the use of over fire air in large scale (480MW) cyclone fired utility boilers. The field tests and modeling results are in good agreement. Final data analysis has been completed for tests performed at Eastlake Power Station of a real-time waterwall corrosion monitoring system. The tests demonstrated that corrosion could be measured accurately in real-time in normal boiler operations, and an assessment of waterwall wastage could be made without impacting boiler availability. Detailed measurements of soot volume fraction have been performed for a coal burner in a pilot scale test furnace. The measured values are in good agreement with the expected trends for soot generation and destruction. Catalysts from four commercial manufacturers have been ordered and one of the samples was received this quarter. Several in situ analyses of vanadium-based SCR catalyst systems were completed at BYU. Results to date indicate that the system produces results that represent improvements compared to literature examples of similar experiments. Construction of the catalyst characterization system (CCS) reactor is nearly complete, with a few remaining details discussed in this report. A literature review originally commissioned from other parties is being updated and will be made available under separate cover as part of this investigation. Fabrication of the multi-catalyst slipstream reactor was completed during this quarter and shakedown testing was begun at the University of Utah pilot-scale coal furnace. Talks continued with two utilities that have expressed interest in hosting a demonstration.
