An equilibrium analysis is carried out to determine the speciation of metals among their various forms in an incinerator. The Gibbs free energy of the system is minimized by the method of element chemical potentials combined with atom population constraints using a thermodynamic equilibrium computer code. Ninety-one compounds of six metallic species-arsenic, cadmium, chromium, lead, mercury, and tin-are analyzed in this study. The effect of temperature and chlorine content on the speciation is established. The effect of combustion of hydrocarbon fuels on the equilibrium calculations is also evaluated.
