An emmission sampling system was developed to measure pollutants emitted from a mobile agricultural incinerator developed at Oregon State University. The system was designed to collect a particulate sample on an 8" x 10" fiber glass filter and collect a gaseous sample in a plastic bag. Pollutants measured were particulates and gaseous hydrocarbons. Isokinetic sampling conditions were impractical to attain on the moving source, but were approximated using velocity measurements made during fixed tests of the incinerator. In order to adjust emission values to 12 percent carbon dioxide, the carbon dioxide content of all gaseous samples was measured with a Beckman infrared analyzer. Total gaseous hydrocarbons were measured with a Perkin Elmer hydrogen flame ionization analyzer. A gravimetric analysis was performed on each particulate sample. A particulate sample was found to consist of 5 percent combustibles and 95 percent uncombustibles. That finding, along with visual observations, indicated a considerable amount of dirt was being entrained with the combustion residue. A particle size analysis was performed by light field microscopy and bimodal distribution was discovered. Data on several typical samples is also included.
