The report gives results of an experimental performance evaluation of four novel fine particulate control devices: the Johns-Manville Cleanable High-Efficiency Air Filtration (CHEAF) System, the APS Electrostatic Scrubber, the APS Electrotube, and the TRW Charged Droplet Scrubber. The evaluations included measurement of inlet and outlet particle size distribution and concentration with cascade impactor and diffusion battery. Fine particle collection efficiencies were computed from the data, as functions of particle size. Mathematical performance models were developed for the CHEAF system and the APS scrubber. The models gave satisfactory predictions.
