Abstract: Optical microscopy is a useful tool for differentiating the performance of coals during pulverized coal combustion. Char morphology is related to the maceral, microlithotype (maceral associations), and rank of coal which in turn control the reactivity. Chars from four overall raw coal samples are obtained by devolatilising them at 900°C in a controlled condition. The char morphology study and pore size measurements are carried out using reflected light optical microscope.
