2. EGTEI-Emerging technologies sub-Group Brussels– 25 th of January 2008 2 Ia/ SO x -NO x -Rox BOx (SNRB TM ) Technology SO x -NO x -Rox Box™ (SNRB™) process (Babcock & Wilcox) Pollutants SO 2, NO x and particulates Process description Process that combines hydrated lime and ammonia injection upstream of hot catalytic baghouse (box) where the solid product calcium sulphite and sulphate and particulate (Rox) are removed, and the NOx is reduced to nitrogen and water. Implementation experience Location Dilles Bottom, Belmont County, OH (Ohio Edison Company's R.E. Burger Plant, Unit No. 5) Year/ Scale 1995 / Pilot Capacity/Production 5-MWel Coal : Bituminous coal blend, 3.7% S

3. EGTEI-Emerging technologies sub-Group Brussels– 25 th of January 2008 3 Ia/ SO x -NO x -ROx BOx (SNRB TM ) No information is available wether this process is actually applied to a large combustion plant. Therefore, no information on the general performance of the SNRB process can be given
