The rank of a coal refers to the degree of coalification endured by the organic matter. It is estimated by measuring the moisture content, specific energy, reflectance of vitrinite or volatile matter (these are known as rank parameters). The IECM's calculation of coal rank is based on Parr. S. W. (1922). The Classification of Coal. The Journal of Industrial & Engineering Chemistry. 14, 10, 919–922.
Some portions of the model depend on this calculation. Pulverized Coal (PC) plants allow the use of biomass, which is not a coal, however the calculation is still applicable.
