In this chapter, I introduce coal as a resource and examine the process of coal generation. I also discuss coal classification and the key characteristics of coal, look in detail at coal sampling and analysis, coking coal, worldwide coal reserves, production methods, basic economic production costs, and the environmental and safety issues …
The NCV for lignite varies between 7.1 and 12.00 MJ/kg and that of CEF lies between 26.0 and 31.0 kgC/GJ. The range NCV for non-coking coal lies between 12.1 and 27.2 MJ/kg and the CEF from 22.2 to 29.5 kgC/GJ. The NCV for coking coal vary from 21.6 to 31.0 MJ/kg and the CEF value ranges from 24.9 to 26.1 kgC/GJ.

Coal = 1245345 tonnes (t) of coal Net Calorific Values (NCV) = 11.9 TJ/Gg Expression to calculate Energy: Energy = Mass * NCV Step 2 – Analyzing the units of the parameters in the equation Coal is expressed in metric tons and we want to obtain Energy in MWh. The NCV is given in TJ/Gg, so we need to transform it to MWh/t.
GCV is coal's most influential rank property and depends on the composition of minerals and maceral [6]. The most exact measurement is GCV generated from a coal sample in a laboratory using an adiabatic bomb calorimeter, but the process is expensive, time-consuming, and tedious [4, 7]. These limitations forced the formulation of different ...
