In recent years, the growing attention to coal quality by coal-burning utilities has led to an increase in coal blending. Coal blending is done with both economics and the quality of coal in mind. To assess the quality of coal, pyrolysis and combustion influencing thermal parameters, as measured in thermogravimetric analysis (TGA) experiments can be applied. The coal industry needs a study to determine relationships that may exist between the measured values of TGA thermal parameters in individual coals and those in the blends. The TGA thermal parameters are the weight loss, Tmax, Ti, T1/2, tmax, tbreak point, tcombustion end point, Rmax and residue. With these relationships, there exists the possibility of accurate prediction of values of these parameters in the coal blends. In this study, a series of coal blends were prepared and thermal parameters for the blends were measured to examine the additive or nonadditive nature of results obtained under both pyrolysis and combustion conditions using thermogravimetric analysis.
