The report gives results of a study that has proven the feasibility of measuring particle size distributions in stack gases (and fractional efficiencies) from 0.01 micrometers. It describes a first-generation system that represents a viable package that can be improved and will continue to be useful in making these extremely important measurements related to the control of fine particles. Three techniques were used to measure particle size distributions in industrial plant environments under a variety of conditions: cascade impactors, in the particle size range 0.5-20 micrometers; diffusion batteries and CN counters, 0.01-0.2 micrometers; and optical counters, 0.3-2 micrometers. The stage collection efficiencies of several impactors and cyclones were also measured in the laboratory. A vibrating-orifice aerosol generator was used for calibration.
