With the ever-growing energy demand over the globe, Nigeria’s demand and utilization of power has been an on-going
problem for decades with less than 40% of rural community connected to the national grid. The need to explore the usage of
safe and naturally abundant materials whose relevance has largely been underestimated in power generation becomes nonnegotiable in order to sustain the socioeconomic development. This paper presents performance of fluidised bed combustion
boiler that depends on the fuel distribution in which agricultural waste solid fuel (corncob) was burnt at bed height of 77mm,
47 mm and 27 mm using 250 µm granular material. The results recorded stability in the superheated temperature of 141oC at
55 minutes, 147oC at 45 minutes and 163oC at 30 minutes respectively. The maximum superheated pressure obtained were 2.1
bar at 55 minutes for bed height of 77mm, 2.6 bar from bed height of 47 mm at 45 minutes and 4.0 bar from bed height of 27
mm from 45 to 55 minutes. Lastly, emission analysis of the flue gas has shown to be low in various percentages of 0.0003% of
NOx, 0.001% HC and 0.02% of CO.
Key words: Corncob, Fluidized bed boiler, Superheated temperature, Electrification, Superheated pressure, Emission
