Coal-derived low smoke fuel assessment through coal stove combustion testing
(Elsevier, 2017)A study was undertaken to investigate the production of low smoke fuel from coal currently used in low-income households in South Africa. Pyrolysis of large coal lumps was studied as a possible production method, and an ... -
The effect of added minerals on the pyrolysis products derived from a vitrinite-rich demineralised South African coal
(Elsevier, 2016)A better understanding of the behaviour of the inorganic matter present in coal will assist in more cost-effective operations and more consistency in product yield and composition during thermal processing. In this study, ... -
The effect of mineral addition on the pyrolysis products derived from typical Highveld coal
(2014)Mineral matter affect various coal properties as well as the yield and composition of products released during thermal processes. This necessitates investigation of the effect of the inherent minerals on the products derived ... -
Influence of additives on the devolatilization product yield of typical South African coals, and effect on tar composition
(SAIMM, 2018)South African coal is mainly used for electricity generation by means of pulverized fuel combustion and liquid fuels production via indirect gasification technology and Fischer-Tropsch synthesis. In order to expand the ... -
Low-smoke fuel production via low temperature pyrolysis of lump coal
(North-West University (South Africa) , Potchefstroom Campus, 2016)Coal is used on a large scale in the Kwadela Township, Mpumalanga, South Africa with the means to fulfil the basic energy requirements of low-income households. Energy within the coal is utilised via combustion thereof in ... -
Product evaluation and reaction modelling for the devolatilization of large coal particles
(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 ... -
Pyrolysis product evaluation and prediction of coals of different rank
(North-West University (South Africa) , Potchefstroom Campus, 2016)When coal is heated slowly (<10 °C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tars, oils and non-condensable ... -
The use of the waste delisting process - case study : the management of ferrochrome slag as a construction product in South Africa
(North-West University, 2008)Ferrochrome slag is a by-product from the production of ferrochrome, an essential component in stainless steel. World wide it is known that ferrochrome slags are been used mainly in the road and civil construction industries, ...
