Abstract
The report summarizes Southern Research Institute's experience with greases and glass fiber filter material used as collection substrates in inertial cascade impactors. Available greases and glass fiber filter media have been tested to determine which are most suitable for flue gas sampling. Greases are probably not useful at above 177C. For higher temperatures, glass fiber filter material can be used. Of 19 greases tested by heating in the laboratory and by exposure to flue gas in the field, only Apiezon H grease performed satisfactorily at above 149C. In experiments to evaluate the use of filter materials as impactor substrates, mass increased as a result of exposure to flue gas for all of the fiber media tested. Laboratory and field studies are described which were directed toward developing a method to passivate glass fiber filter material to SOx induced mass gains. These studies indicate that a H2SO4 wash, followed by a thorough distilled water/isopropanol rinse, drying, and baking, augmented by in situ conditioning, offers the best hope for reducing SOx induced mass gains. Reeve Angel 934AH glass fiber filter material performed best among the media tested.
