| Description |
Indian coal-based thermal power stations produces huge amount of coal combustion residues.
Proper disposal, management and utilization of these ashes have always been a challenge before
the thermal power plant management people. In order to find out the potential use of coal
combustion residues one need to explore and look deeply into its various characteristic properties.
In the present study the coal combustion residue samples from thermal power station of eastern
India were used for characterizing ashes on the basis of Transmission Electron Microscopy
technique. The study of the micrographs of Transmission Electron Microscopy showed that the coal
combustion residue samples consisted of all the three viz. crystalline, polycrystalline and
amorphous phases. The coal combustion residue samples were found to consist of single crystal,
single crystal with hexagonal structure, polycrystalline substances and closed packed hexagonal
structure. Concentric circles as seen in the diffraction pattern show the presence of polycrystalline
substances in the samples. Presence of plerosphere in the coal combustion residue samples can
also be seen from some SEM micrographs as well as one of TEM images. XRD studies show the
presence of various crystalline substances present in the coal combustion residues. The study
shows that the CCR samples are typically formed of Si-Al-Fe system with traces of sodium,
potassium, calcium, magnesium, sulphur and titanium
