Abstract

This study investigates the effects of the characteristic temperatures of the burning profile on the reactivity of 15 lignite samples originating from different areas of Turkey. Nonisothermal thermogravimetry has been used to determine the combustion reactivity of the samples. The combustion activation energies were calculated by the Coats Redferm method from their TG data. It was observed that the characteristics of the temperatures of the burning profile had an important effect on the activation energy of the lignite samples and that there are definite correlations between them.
