Abstract: In this study, a miniature fluidised bed boiler for steam generation was designed and constructed. The boiler ismade up of a steam drum, combustion chamber, downcomer and riser tubes as a heat exchanger, a non-return valve andsuperheater 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 performanceevaluation of the fluidised bed...
