Abstract
Sulfuric acid from condensed sulfur trioxide (SO3) has been found in the filtering medium used in the EPA/APCO, WP-50, and high-volume sampling methods. The amount of sulfuric acid ranged from 1 8 to 78% of the total particulate matter found when sampling emissions from oil-fired boilers. These levels were high enough to determine whether a unit is in compliance with regulations. A question is raised as to whether condensed sulfur trioxide should be included in particulate measurements or eliminated after analyzing the filter medium.Keywords
