Özet

In this study, combustion characteristics and kinetics of three coal samples are examined. A series of thermogravimetry (TG-DTG) and differential scanning calorimetry (DSC) measurements were carried out in non-isothermal conditions at heating rates of 5, 10, and 15 K min(-1). Reaction regions, peak and burn-out temperatures, mass loss, and heat of reactions of the samples were determined for each heating rate from TG-DTG and DSC curves. A variety of computational methods, available in the software developed, were applied to experimental data for the evaluation of the kinetic parameters of the coal samples, and the results are discussed.
