New Techniques for Thermochemical Phase Equilibria Predictions in Coal Ash Systems - II

Ramanathan, M.; Kalmanovitch, D.P. and Ness, S.
To be published in Prog. Energy Comb. Sci., Special Issue on Ash Deposition, Pergamon Press, 1989. Funded by ACERC (National Science Foundation and Associates and Affiliates) and US Department of Energy.

PHOEBE is a new computer code developed at UND-EMRC as part of a long-term study of coal ash deposition phenomena in coal combustion systems. The task of developing a new code was undertaken to eliminate the various problems encountered with existing phase equilibria calculation packages and to apply better techniques in the minimization of the Gibbs free energy of the system. The results from PHOEBE for a couple of thermodynamic systems are presented and compared with their corresponding experimental values.
