Brown coal is calculated as the sum of sub-bituminous coal and lignite (Mills, 2011). Sub-bituminous coal is defined as non-agglomerating coal with a gross calorific value between 4165 and 5700 kcal/kg on moist ash free basis. Lignite is defined as non-agglomerating coal with a gross calorific value on moist ash free basis < 4165 kcal/kg.
