  • Ash Yield in Coal (Proximate Analysis), Kentucky

    Ash yield is measured to determine how much material remains (called ash residue) after a coal is combusted. Ash yield is measured directly in an automated proximate analyzer or ashing furnace. Results are presented in weight percent. The ash yield of a coal sample is the amount of material remaining after combustion.

    Calculated yield % and ash % values with experimental yield % and ash % values from float–sink data of the used coal were also compared and they were in good agreement (R 2 > 0.99). By equalization of the incremental ash in order to get composite ash of 9.5%, the composite yield was maximized to 30.71% while the plant's yield was about 24.00%.
