Effect of Co-Axial Promoters (Rod and Disc Type) On Pressure Drop in Squared Gas-Solid Fluidized Bed

Abstract

This paper deals with the experimentation conducted to obtain pressure drop in a squared gas-solid fluidized bed under varying conditions. The flow rate, the initial static bed height, particle size and density have been altered; and the bed pressure drops under fluidizing conditions have been measured. The data have been correlated in terms of Euler Number. Correlations relating Euler Number with the system parameters have been developed for the unpromoted bed and beds with rod and disc promoters. Developed correlations have been authenticated by an ANN-model. The values of Euler Number thus predicted as well as the bed pressure drop values calculated there-of have been compared with the experimental values and have been found to agree fairly well.
