Abstract
In this study, a sub-bituminous coal was theoretically analyzed. Interpreting the CCSEM analysis data, the mass weight percent of included and excluded minerals in the entire mineral group was calculated to determine the mineral particles number. Coal particles size and mass distribution was calculated using Malvern analysis. Included mineral particles before combustion were redistributed into the coal matrix. Based on the statistical results of previous studies, fragmentation and coalescence of included and excluded minerals after combustion were calculated. Total number of residual ash particles with the details of their mass and size distribution in mineral groups were calculated. After transformation, total number of excluded mineral particle for 1 kg of KPU coal increased from 274 billion to nearly 281 billion due to fragmentation of some mineral phases. Total number of included mineral particle reduced from 351 billion to 27 billion for the same amount of coal because of coalescence.
