The impacts of coustion emissions on air quality …

The high metal content of the particulates from the high temperature coustor arises from vaporization of the metals under the high coustion temperatures followed by nucleation, coagulation and condensation onto existing particles (Linak et al., 2000b). The extent of metal vaporization is dependent on the extent of carbon coustion.
