Particulate emissions from energy systems

Abstract

General models of aerosol dynamics, originally developed to simulate atmospheric aerosol behavior, have been extended for application to combustion and other high temperature processes. These models are now being used to study the fate of ash vapors in conventional pulverized-coal combustion. Field measurements have shown that the vapors condense preferentially on the surfaces of the smaller ash particles. Previous simplified calculations have suggested that large numbers of very small particles may also be formed by the condensation of these vapors. The new, exact calculations will be used to explore the relative importance of new particle formation and condensation on existing particles, the size distributions of the particles produced under various combustion conditions, and the distribution of chemical composition with respect to particle size.
