Development of a Cascade Impactor System for Sampling 0.02 to 20 Micron Diameter Particles

摘要

An improved cascade impactor sampling train was constructed to size particles emitted from electric power utility generating stations. The new sampling train components were designed to accompany the UW Mark 3-4 Source Test Cascade Inspector. The capability of this instrumentation to perform in-stack particulate sizing in the 0.02 to 20 micron diameter range has been demonstrated. Source tests were conducted at the coalfired power boiler at the 0. E. Curette power Plant, Billings, Montana, the Nula Power Plant, Nula, Colorado;and the University of Washington Power Plant, Seattle, Washington.
