The technology of fluidized bed coal combustion (FBC) and its advantages over conventional coal burning systems is now well established and is extensively reported in the literature. There is also some emphasis in literature about the suitability of LafiaObi coal in FBC. However, there is little quantitative or qualitative information on theperformance of LafiaObi in FBC.
