John Darrow, Energy Market Specialist at W.L. Gore & Associates, Inc., described the characteristics of ePTFE membrane filter media and compared them to other media available. He said that 35 EGUs were now using this material. However, because of higher material cost, it was not necessarily the best solution for every power plant. He described a four-step process to go through to determine what the best media would be for a specific power plant to achieve the objective – “Getting the Lowest Annualized Cost w/o Emissions Problems.”

Chet Moon, Technical and Applications Manager at Toray Fluorofibers (America), Inc., presented performance data for the range of fibers Toray offers for filtration applications. He said that currently Toray PPS TORCON® is the most suitable fiber to meet most of the filtration needs of coal-fired boilers. However, in the future it may be necessary to utilize one of the more expensive Tefaire® and Teflon® products to meet the regulated limits.

Charles Barranger, Senior Consultant at EPSCO International, Inc., discussed the styles of baghouses in use, QA/QC procedures and criteria for selecting filter media. When asked how cost figures into the selection criteria, he stated that life cycle cost is very important but it needs to be balanced against the required efficiency. He also offered techniques for improving the performance of filters to achieve lower particulate emissions.

Dr. John D. McKenna, Ph.D., principal and founder of ETS, Inc., reviewed the regulations for PM2.5 and the filter media options for complying with the coming emission limits. He also discussed the standard test methods available for evaluating the performance of various filter materials including EPA’s ETV Generic Verification Protocol for Baghouse Filtration Products, ASTM D 6830, and the proposed ISO method that he said should be issued next March after ten years of work. He reviewed the elements of a bag quality control program and emphasized that a good QA/QC program will be essential to obtaining compliance and efficient baghouse operation.
