Abstract: This paper describes the influence of mechanical activation of coals on ignition and thermal-oxidative degradation using two independent methods: thermogravimetric analysis and ignition of a dust suspension in a vertical pipe furnace. It is determined that the ignition temperature of mechanically activated coals decreases and that mechanical activation affects the further process of thermal-oxidative degradation.

Keywords: mechanical activation, thermogravimetric analysis coal, ignition, thermal degradation kinetics, synchronous thermal analysis, ignition temperature.
