Zinc aerosols from steelmaking EAF: morphology and growth.

Controlling the emission of zinc from electric arc furnaces poses a challenge, either in terms of compliance or of filter performance. This aerosol occurs significantly within the penetration window of control devices (Flagan and Seinfeld, 1988). This could be compensated through the enhancement of other removal mechanisms, such as the use of adsorbents or the scavenging onto coarse particles coflowing with the Zn-rich fine fraction (Friedlander et al. 1991). The potential improvement -an engineered modification of inlet size distribution at the control deviceshould be carefully considered (Owens et al, 1996; Linak et al, 1993).
