Description

Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month continued with the Phase I DOE/PRDA investigation of the Clear Liquor Scrubbing Process with Anhydrite Production and Chloride Control. The Phase I DOE/PRDA testing of the B&W/Condensing Heat Exchanger (CHE) also continued this month as the inlet particulate control system (installed September 1996) is maintaining the inlet particulate mass loading to the unit at an average value of 0.2 lb./MMBTU. The one-year tube wear analysis project conducted across this unit will be completed in the early part of ... continued below

Description

Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month continued with the Phase I DOE/PRDA investigation of the Clear Liquor Scrubbing Process with Anhydrite Production and Chloride Control. The Phase I DOE/PRDA testing of the B&W/Condensing Heat Exchanger (CHE) also continued this month as the inlet particulate control system (installed September 1996) is maintaining the inlet particulate mass loading to the unit at an average value of 0.2 lb./MMBTU. The one-year tube wear analysis project conducted across this unit will be completed in the early part of March. At the completion of testing, a final inspection will be conducted before the unit is cleaned, disassembled, and returned to B&W and CH Corp. for additional analysis. Once the unit is removed from the ECTC, the 0.4 MW Mini-Pilot Wet Scrubber unit will be assembled and configured back into the flue gas path for future testing. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the Carbon Injection System (the Pulse-jet Fabric Filter configuration) remained idle this month in a cold-standby mode and were inspected regularly. In February 1997, the Clear Liquor Scrubbing with Anhydrite Production test block continued. This PRDA project is being jointly funded by the Electric Power Research Institute and the Department of Energy and is part of the DOE`s Advanced Power Systems Program, whose mission is to accelerate the commercialization of affordable, high-efficiency, low-emission, coal-fueled electric generating technologies. The pilot portion of the CLS/Anhydrite project is being conducted on the 4.0 MW wet FGD pilot unit at EPRI`s Environmental Control Technology Center (ECTC). The project is designed to develop an advanced FGD process incorporating chloride control, clear liquor scrubbing, and anhydrite (anhydrous calcium sulfate) production. While the three areas of the integrated process can be used independently, they work together in a manner that benefits the overall process. The HCI control process involves controlled humidification of the flue gas with a slurry containing a calcium-based alkali. The potential advantages of the HCI control process include: Helps control scaling in CLS process and increases the anhydrite production rate. Reduces the chloride concentration in FGD solutions which reduces the corrosion rate of alloys and increases the limestone dissolution rate (through calcium common ion effect).
