Chad Teply of BHE testified in 2012 as to the reasons SCR and CaBr2 injection were the best choice for Jim Bridger 3 & 4. The substantial capital investment was based on a retirement date of these units in 2037. The unit 3 system was to be installed in 2015 and unit 4 in 2016. The Jim Bridger Units 3 and 4 emissions control investments proposed in the Request are SCR systems and associated ancillary equipment for each unit. Each SCR system would be comprised of two separate universal reactors, with multiple catalyst levels; inlet and outlet ductwork; a shared ammonia reagent system; an economizer upgrade; structural reinforcement of the boiler and flue gas path ductwork and equipment; and extension of the existing plant distributed control system (“DCS”). An induced draft (“ID”) fan upgrade and an associated auxiliary power system variable frequency drive (“VFD”) insertion is required on Unit 4 only. Jim Bridger Units 3 and 4 it will be necessary to add a coal additive, namely calcium bromide (“CaBr2”), to oxidize mercury and then add a scrubber additive to prevent readmission of mercury in the scrubber system. The potential exists to reduce the coal additive requirements due to the SCR. Click Here For Complete Article Text
