Abstract: In this study, a miniature fluidised bed boiler for steam generation was designed and constructed. The boiler is
made up of a steam drum, combustion chamber, downcomer and riser tubes as a heat exchanger, a non-return valve and
superheater tube. Experimental investigation on the fuel distribution was carried in two-dimensional chamber with crosssection of 500 mm x 1000 mm and bed height of 77 mm, 47 mm and 27 mm. The results obtained from the performance
evaluation of the fluidised bed boiler operated with corncob at constant feed rate of 6kg/h for various bed heights of 77 mm,
47 mm and 27 mm recorded stability in the saturation temperature of 121oC at 50 minutes, 144 oC at 45 minutes and 153 oC
at 30 minutes, respectively. In additional, saturation pressures of 2.0 bar from 50 to 55 minutes for bed height of 77 mm, 2.1
bar from 45 to 50 minutes for bed height of 47 mm and 3.6 to 3.7 bar from 45 to 55 minutes for bed height 27 mm were
obtained. The effect of fuel particle size on emissions and overall combustion efficiency of corncobs has proven to be
efficient in a fluidised bed boiler as the emission analysis of the flue gas has shown to be low in various percentages of
0.0003% of NOx, 0.001% HC, 0.02% of CO and 0.93% of Nitrogen, respectively.
