説明
The accuracy of a thermogravimetric analysis (TGA) for the determination of moisture, volatiles, fixed-carbon and ash in coal was investigated. The method consists of the following 4 sequential steps: (1) preparation: Load a 50 mg sample of constant humidity base coal to a thermobalance and purge high-purity nitrogen into a furnace. (2) moisture determination: Heat the sample up to 107 °C in a nitrogen atmospher and hold it at the temperature for 10 min. (3) volatiles determination: Increase furnace temperature up to 900 °C and hold at the temperature for 7 min. (4) fixed-carbon determination: Decrease furnace temperature to 815 °C and switch furnace environment from nitrogen to high-purity oxygen. After each procedure, the weight losses of each component were measured as percentages to the total sample weight. In regard to moisture, fixed-carbon and ash contents, the results by the TGA method were in good agreement with those of JIS method. For the volatiles, however, TGA showed a little lower values than those by JIS method.
