The caking and swelling of South African large coal particles

Coetzee, Sansha (2015)

The swelling and caking propensity of coals may cause operational problems such as channelling and excessive pressure build-up in combustion, gasification and specifically in fluidised-bed and fixed-bed operations. As a ...
The properties of large coal particles and reaction kinetics of corresponding chars

Everson, R.C.; Neomagus, H.W.J.P.; Van der Merwe, G.W.; Koekemoer, A.; Bunt, J.R. (Elsevier, 2015)

An investigation was undertaken to determine the distribution of chemical-, petrographic- and mineralogical properties of large coal particles of different sizes and densities and to evaluate a suitable reaction rate model ...
The transient swelling behaviour of large (-20 + 16 mm) South African coal particles during low-temperature devolatilisation

Coetzee, Sansha; Neomagus, Hein W.J.P.; Bunt, John R.; Strydom, Christien A.; Schobert, Harold H. (Elsevier, 2014)

In order to predict coal behaviour during certain utilisation processes, and to improve and develop coal conversion technologies, it is important to understand the swelling behaviour and plastic properties of coal. X-ray ...
