The report gives results of fractional and overall mass efficiency tests of four novel particulate control devices. Three were wet scrubbers: an Aronetics (Chemico) Two-Phase Jet Scrubber, an Entoleter Centrifield Scrubber, and a CEA Variable-Throat Venturi Scrubber. The fourth was a Rexnord Gravel-Bed Filter. The devices were used for controlling emissions from a submerged-arc ferroalloy furnace, an asphalt batching plant, a pulverized-coal-fired utility boiler, and a portland cement clinker cooler, respectively. Total flue gas particulate mass concentrations and emission rates were determined at device inlets and outlets by conventional techniques. Inlet and outlet emission rates as functions of particle size were determined on a mass basis using cascade impactors for sizes from about 0.5 to 5 micrometers, and on a number basis for sizes smaller than 1 micrometer using optical and diffusional and/or electrical mobility methods. The report includes brief descriptions of the control devices and the process on which each was utilized, the measurement methods, inlet and outlet size distributions, and overall and fractional efficiencies.
