Electric Power Research Institute: Environmental Control Technology Center report to the Steering Committee. Final technical monthly report

Operations and maintenance continued this month at the Electric Power Research Institute`s Environmental Control Technology Center. Testing on the 4.0 MW Pilot Wet FGD unit continued this month with the Trace Element Removal test block (TER) as the Pilot was operated under forced oxidation conditions. With this testing, the mercury measurement (Method 29) studies also continued as investigations into various activated carbons, metal amalgams, and impinger capture solutions were conducted. Following these studies, a brief test of the Pilot High Velocity FGD configuration (PHV) was conducted. This test block will be continued at the end of the month after the Fall outage is completed. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit remained idle this month in a cold-standby mode. During this month`s outage, the inlet and outlet damper plates were sealed to isolate the SCR system from flue gas. Also, the internals of the heat pipe heat exchanger (HPHE) and catalyst reactor tower were inspected and cleaned so that the system could be available for future test activities. Monthly inspections of all SCR system equipment placed in this cold-standby mode, as well as the fire safety systems in the SCR building, will continue to be conducted by the ECTC maintenance department and will include manual rotation of the booster fan
