Wind tunnel evaluation of particle sizing instruments. Final task report. [Fly ash from coal-fired power plant at concentrations corresponding to clean and dirty stack conditions]
Technical Report

OSTI ID:7331503
The report gives results of an experimental study, undertaken to evaluate and compare several particle sizing instruments. Fly ash from a coal-fired power plant was redispersed and fed into a wind tunnel at concentrations corresponding roughly to clean and dirty stack conditions. Data were obtained with two standard cascade impactors (using gravimetric mass determination), a set of series cyclones, a cascade impactor with piezoelectric crystal sensors, a cascade impactor using beta attenuation to determine collected mass, and an optical single-particle counter using a laser light source. No simple correlation could be established between the results of the optical instrument and those of the inertial classification devices, due to the probable nonuniformity of particle shape and density.
