Treatment of fly Ashes Model by PTA : Modeling and Experimental Results on Pollutants Evaporation

A plasma transferred arc reactor was designed to follow on-line, by ICP, the evaporation of zinc chlorides and sulphates impregnated in a zeolite matrix (fly ash model). The zeolite granules were injected in a graphite crucible on which the transferred arc, in an argon atmosphere, was transferred. Zinc evaporation was modelled using a first order law, making it possible to determine the evaporation constant k of the law and providing good agreement with the experiment. 10 refs.
