AIR CLEANING STUDIES. Progress Report for July 1, 1956 to June 30, 1957

Progress is report on the air and gus cleaning project conducted by Harvard University for the Division of Reactor Development of the U.S. Atomic Energy Commission. Design modifications in a commercial automatic sampler to convert it for use as a continuous stack monitor are described. Studies on electrostatic mechanisms in particulate collection were centered on an experimental device consisting of fluidized plastic granules. Evaluation of commercial dust collection apparatus included tests on a device having an electric field superimposed on fiber matting, a new type wet collector, and a high velocity cyclone. Progress is reported in studies on the design of gas cleaning equipment for an institutional type incinerator, investigation of iodine and carbon floc removal from high-temperature gas streams, an economic survey of gas cleaning costs within the AEC, the development of filter equipment to collect NaK fume, and preporation of apparatus for a field study on blast effects on air cleaning systems. Publications during the period are listed, and consulting and training activities during the period are summarized. (For preceding period see NrO-4809.) (C.H.)
