Relationship between proximate analysis parameters and

 · Considerable literature existing on coal combustion is focused on low ash (< 10 ) content coal (Chen et al. 2015). In contrast Indian utilities burn coal having very high ash content typically 30 –40 and sometimes up to 50 (Zhang et al. 2013a b). Combustion behaviour of these high ash coals could be different from that of low ash coal.
