To preserve fossil fuel resources, it is important to develop the efficient use of low rank coals like brown coal and lignite all over the world. Upgraded Brown Coal(UBC), which is the coal dewatered and stabilized in heated oil, is the promising way to use low rank coals as well as bituminous coals. In this paper, fundamental combustion characteristics and kinetics of UBC are examined via thermo-gravimetric(TG)analyses and Drop Tube Furnace(DTF)experiments. They are compared with those of bituminous coal. The UBC seemed to have higher reactivity during combustion than bituminous coal. There is a difference in the volatile evolution process between the UBC and bituminous coals.
