Standard Test Method for Major and Minor Elements in Coal Ash By X-Ray Fluorescence

Importancia y uso:

5.1 A compositional analysis of ash is used in describing the quality of coal for its complete characterization. Ash composition is useful in predicting slagging and fouling characteristics of combusted materials as well as the potential utilization of ash by-products.

5.2 The chemical composition of laboratory prepared coal ash is rarely, if ever, representative of the composition of the mineral matter in the coal because the ashing process can alter some minerals. However, it can approximate the composition of the fly ash and slag resulting from commercial combustion of coal.
