Equilibrium Composition of Simulated Coal Combustion Products: Relationship to Fireside Corrosion and Ash Fouling.

Wilson JS; Redifer MW
Trans Asme J Eng for Power 1974 Apr; 96(2):145-152
A computer solution of chemical equilibrium composition is presented for high-temperature combustion reactions related to fireside corrosion and ash fouling. A simple calculation system, which models the injection of a sodium-potassium mixture through a flame, is solved for equilibrium compositions of temperatures from 1,500 deg. to 3,000 deg. F at oxygen levels in the gas stream ranging from 0.1 to 17 percent and 1 atmosphere pressure. At equilibrium, principally alkali sulfates and hydroxides are produced in the model of a combustion product atmosphere resembling that in a coal-fired boiler. A total of 42 reactions involving 40 chemical species were treated in the reactant mixture, and compositions for the entire system are included.
