Abstract :
In this research, the results of a study on the combustion characteristics of Soma lignite before and after cleaning are presented. Non-isothermal thermogravimetry (TG/DTG) experiments were carried out for four different size fractions. Experiments were performed from ambient to 900°C in air atmosphere at 10°C/min heating rate. TG/DTG curves revealed three reaction regions. The first region is due to the evaporation of moisture in the coal. The second region can be called the primary reaction region, whereas third region is related to the decomposition of mineral matter in the lignite. Kinetic analysis has revealed that increase in reactivity and long-lasting combustion is the distinctive effect of cleaning on combustion characteristics of Soma lignite.
