The SOx-NOx-Rox Box{trademark} (SNRB) is an advanced air pollution process patented by Babcock and Wilcox (B and W) that provides for significantly reduced sulfur oxides (SO{sub x}), nitrogen oxides (NO{sub x}), and particulate emissions from coal-fired boilers. The process uses a high-temperature catalytic baghouse for integrating SO{sub x} reduction through injecting an alkali sorbent (such as hydrated lime or sodium bicarbonate), NO{sub x} removal through ammonia injection and selective catalytic reduction (SCR), and particulate collection. The advantages of the process include: compact integration of the emission control technologies into a single component; dry sorbent and by-product handling; and improved SCR catalyst life due to lowered SO{sub x} and particulate levels. The SNRB concept has been successfully demonstrated in a 1,500-ACFM pilot baghouse at B and W's Alliance (Ohio) Research Center. This paper describes the SNRB technology presents the SO{sub x}, NO{sub x}, and particulate removal performance results over a range of operating conditions for the laboratory pilot test program.
