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 Lafia-Obi coal in FBC. However, there is little.

Quality of Some Nigerian Coals as Blending Stock in Metallurgical .

Two Nigerian coals, Lafia-Obi and Chikila were blended in the mass ratio of 70:30 with imported American and Polish coking coals. Proximate analysis, free swelling index, Ruhr dilatometer and Gieseler plastometer were used in assessing the coking qualities of both the single coals and the blends. The results show that.

Characterization of Some Nigerian Coals for Power Generation

Mar 31, 2016 . Jauro and Chukwu [9] investigated three Nigerian coals (Onyeama, Lafia-Obi, and Garin Maiganga) to determine their suitability in developing formed coke for use as blast furnace coke. Parameters that were used include the shatter index expressed as percentage stability and friability and mecum index.

Petrographic studies and proximate analysis of coal samples from Lafia-Obi, Chikila and Lamza deposits of the Benue Trough, were used in the ranking and preliminary assessment of the coking potential. Vitrinite reflectance measurements show that the Lafia-Obi is of high volatile A rank, while both the Lamza and Chikila.

This, combined with petrography and Rock-Eval pyrolysis were used in assessing the hydrocarbon generating potentials of the coal samples. Lafia-Obi coals were found to have a percentage vitrinite reflectance (%R o ) values of 0.91-1.08 %, maximum temperature for hydrocarbon generation (T max ) of 449-455 oC and a.
