OSTI ID:5325368
In December 1987, Public Law No. 100-202, as amended by Public Law No. 100-446, provided $575 million to conduct cost-shared Innovative Clean Coal Technology (ICCT) projects to demonstrate emerging clean coal technologies that are capable of retrofitting or repowering existing facilities. One of the sixteen projects selected for funding is a project proposed by Babcock Wilcox (B W) to demonstrate the SOX-NOX-ROX BOX (SNRB) flue gas clean-up process. The SNRB process combines the removal of SO{sub 2}, NO{sub x}, and particulates within one unit -- a high temperature baghouse. Sulfur dioxide is removed by injecting a sorbent, either sodium- or calcium-based, into the flue gas between the upper part of the boiler combustion zone and the economizer outlet. The sorbent reacts with the SO{sub 2} to form a solid particulate, which is removed in the baghouse. The NO{sub x} reduction is accomplished by selective catalytic reduction (SCR) using ammonia injected upstream of the baghouse. Some NO{sub x} removal occurs in the presence of injected sorbent, while the balance is removed in the presence of the SCR catalyst in the baghouse. 6 figs., 1 tab.
