Abstract

Coal thermoelectric power plant emits bottom ash as by-product. The bottom ash causes environmental problem and lack of landfill. Combustion technology for pulverized coal blended with the bottom ash has been an issue. In this study, in order to understand the kinetic characteristic for the combustion, thermo-gravimetric analysis (TGA) was carried out under air atmosphere and isothermal condition at temperatures of 800°C, 900°C, 1000°C, and 1100°C. The blending ratios of coal and bottom ash were 1, 0.9, and 0.8. The kinetic parameters (A, Ea) were obtained by Volume Reaction Model (VRM), Shrinking Core Model (SCM), and Random Pore Model (RPM) from the TGA experimental data. The activation energy (Ea) and frequency factor (A) of coal and bottom ash-air reaction were determined using the Arrhenius equation.
