Abstract
Under tightly constrained experimental conditions (particle size<75 mu m, sample mass 5.0 +/- 0.5 mg, heating rate 15 degrees C min(-1), dry air purge 50 mL min(-1), maximum temperature 900 degrees C) a repeata bility of < +/- 2 degrees C, may be achieved for significant temperatu res that characterize the differential thermogravimetric burning profi les of typical medium-volatile, bituminous Australian Gondwanan coals and high-volatile, bituminous New Zealand Cretaceous-Tertiary coals.
