Abstract The report gives results of thermodynamic equilibrium calculations for anticipated operating ranges for various fluidized-bed combustion (FBC) designs used to predict the potential volatility and interaction of 31 trace and minor elements contained in coal and sorbent feedstocks. The quantitative distribution of combustion products for trace and minor elements was predicted on the basis of assumptions concerning the multi-chemical reactions and interactions occurring throughout the FBC system. Predicted equilibrium concentrations for stack gas emissions and bottom ash material were correlated with in-field data for elemental partitioning. Potential pollutants of concern were identified based on discharge multimedia environmental goals (DMEGs). For the gaseous emissions stream, 13 elements were projected to exceed the DMEGs. For the solid waste stream, 15 elements were projected to exceed the land DMEGs. These predictions should be useful in identifying elements for sampling and analysis during future field testing of FBC emissions and solid waste. Further thermodynamic model refinements are recommended.
