Characterisation of coal and chars in fluidised bed gasification

Author: Oboirien, BO ; Engelbrecht, AD ; North, Brian C ; Du Cann, VM ; Falcon, R Date: Mar 2009 There is currently a gap in the understanding of the morphological transformations experienced by high ash and intertinite-rich coals undergoing conversion to char during atmospheric gasification. In this study, work has been carried to ... Read more
Mineral-char interaction during gasification of high-ash coals in fluidized-bed gasification

Author: Oboirien, BO ; Engelbrecht, AD ; North, Brian C ; Eramus, RM ; Falcon, R Date: Sep 2011 The mineral-char interaction can occur during the gasification of high-ash coals in fluidized-bed gasifiers when the melted minerals cover the char surface by penetrating into the cracks and pores of the char. In addition to the physical ... Read more
Study on the structure and gasification characteristics of selected South African bituminous coal in fluidised bed gasification

Author: Oboirien, BO ; Engelbrecht, AD ; North, Brian C ; Du Cann, VM ; Verryn, S ; Falcon, R Date: Oct 2009 The gasification characteristics of three South African bituminous coals were investigated in a bubbling fluidised bed reactor. The three coals are similar in rank, but two are inertinite-rich coals and the third has high vitrinite content. ... Read more

Textural properties of chars as determined by petrographic analysis: comparison between air-blown, oxygen-blown and oxygen-enriched gasification

Author: Oboirien, BO ; Engelbrecht, AD ; North, Brian C ; Du Cann, VM ; Falcon, R Date: Nov 2012 In this study, the textural properties of chars generated from a vitrinite, high ash coal in a fluidised bed gasifier under air-blown, oxygen-blown and oxygen-enriched conditions were determined by detailed petrographic analysis. The char ... Read more
Utilisation of low grade fuels influidised bed combustors

Author: North, Brian C ; Falcon, R Date: Nov 2010 This presentation highlights the utilisation of low grade fuels in Fluidised Bed Combustors (FBC) with regards to South African coal. It looks at types of coals and fuels tested, test facilities and examples of FBC’s at the CSIR. Benefits ... Read more
