Abstract

This paper presents a transferred arc plasma process studying the fly ash evaporation synergies. The lead and zinc evaporations are following on-line by an ICP analysis system. The influence of the plasma parameters and the fly ash composition on the evaporation is presented. The modeling of the heat transfer red to the bath is presented
