Statistical Analysis of Bed Fluctuation Ratio in Gas-solid Fluidized Bed with Rod Promoter

Abstract

A model equation for the prediction of bed fluctuation ratio in rod promoted gas-solid fluidized (condition above quicksand) bed has been developed using statistical design of experiments approach. Four rod promoters of varying volume blockage together with bed materials of four densities and four initials static bed heights have been used in the investigation. A comparison has been presented between the predicted values of bed fluctuation ratio using proposed model equation and the corresponding experimental ones for the test data. The mean and standard deviations of the predicted values of bed fluctuation ratio from the corresponding experimental ones show fair agreement.
