coal is entirely burned, indicates the useful energy content of coal (Patel et al. 2007). A greater GCV indicates that less coal is needed to produce one unit of electricity (Mahapatra 2016). Therefore, the GCV provides an estimation of the plant's produc- tion costs. The GCV of coal forms part of the critical parameters that can be used in ...
• For imported coal, GCV was reported on 'Air Dried basis' (ADB) while paying for coal imports. • For payment to domestic coal companies for supplies, GCV was reported on 'Equilibrated basis' (EB) • For energy billing, the stations reported GCV on 'Total Moisture basis'(TMB) The different methods used for assessing GCV lead to ...

The Moisture in the Coal is both these put together and is the "Total Moisture." A coal sampled at the mines having a moisture of 20%, after storage for a few weeks, when entering the boiler can have moisture of only 8%. If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV.

Introduction. Fossil fuels including fuel oil, natural gas, and coal mostly meet the world's energy needs (Hagen and Robinson Citation 2002).With regards to fossil fuels, coal is the most plentiful energy source, accounting for 40% of global energy (Mathews et al. Citation 2009).Coal provides 77% of South Africa's energy needs, 95% of this energy …
