Coal is one of the reserve sources of fuel for many industrial applications. For example, in a coalfired power plant, coal significantly contributes to the operating costs of the plant. The control over the fuel cost and the level of fuel management can directly affect the economic benefits of the coalfired power plant. In this study, we have developed a generalized calculation methodology ...
