    • Primary fragmentation of large coal particles 

      Badenhorst, Charlotte Johanne (2016)
      When rapidly exposed to high temperatures coal tends to fragment into several pieces due to thermal and volatile release stresses. This is known as primary fragmentation and is one of the major problems opposing the optimum ...

    • Product evaluation and reaction modelling for the devolatilization of large coal particles 

      Hattingh, Barend Burgert (North-West University, 2012)
      A fundamental understanding of the process of devolatilization requires extensive knowledge of not only the intrinsic properties of the parent coal and its subsequent formed products (tars, gases and chars), but also its ...
