51. Quantitative Analysis of Inorganic Elements in Coal and Its Application to Slagging Evaluation

Abstract

Inorganic constituents in coal are incorporated as discrete mineral particles, ion-exchangeable elements, or coordination complexes. As the mode of incorporation effects the ash formation behavior during combustion or gasification, the quantitative analysis of these forms will be useful in predicting slagging properties. The individual mineral particles having different chemical compositions were determined by CCSEM. The leaching test was also carried out for the analysis of ion-exchangeable elements.
