Low Particulate Emissions - Short and Long Term by Charles Barranger, EPSCO - Hot Topic Hour October 28, 2010

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.

Fabric Selection for Coal-fired Boilers Webinar - Hot Topic Hour October 28, 2010

A large group of attendees heard five very good presentations related to the selection of the best filter media to meet the various coming regulations for PM2.5. Attendees agreed that the fundamental filtration capability of the vast majority of fabrics available today, as measured by laboratory tests, far exceeds any existing or expected emission control requirement and the performance of many is below the minimum detectable limit of the test methods. Several presenters pointed out that while the results of these evaluations can be a good guide for filter efficiency and pressure drop, the actual performance of filter material will rarely achieve the levels seen in these tests. This is because the actual performance is dependent on many factors related to the specific site conditions. This causes a concern in the industry that regulators will assume that lab test results are indicative of actual performance and expect the same performance at every installation. Dr. McKenna indicated that because filter media performance was so good, future enforcement will most likely be focused on plant baghouse O&M. He also stated that it will be important to demonstrate what aspects of O&M plans are practical and valuable, so that regulators do not make these plans an operational nightmare.
