    Coal gangue has a potential to be used as fuel in a circulating fluidized bed boiler. However, there are few studies on it in South Korea. In this study, the combustion characteristics and kinetics of coal gangue were investigated by thermogravimetric analysis at different heating rates (20, 30, and 40°C/min) under air atmosphere.
