Title: Significance of the particle physical properties and the Geldart group in the use of correlations for the prediction of minimum fluidization velocity of biomass–sand binary mixtures
Authors: Caceres-Martinez, Louis Edwards, Guío-Pérez, Diana Carolina, 1985, Rincon-Prat, Sonia Lucia
Source: Biomass Conversion and Biorefinery. 13(2):935-951
Subject Terms: Minimum fluidization velocity, Geldart classification, Gas-solid fluidization, Residual biomass, Binary mixtures, Pressure drop correlations
Description: The present study explores the relevance of the physical properties of biomass particles on the determination of the minimum fluidization velocity (U-mf) of binary mixtures. Fluidization experiments were performed in a cold flow unit with diverse biomasses mixed with sand in different mass fractions. Gas velocity and pressure drop across the bed were used to determine U-mf. Different correlations reported in the literature were evaluated on their ability to accurately predict U-mf of the mixtures. Results showed satisfactory predictions when appropriately identifying correlations according to the corresponding Geldart groups for the biomass particles. This perspective opens new possibilities toward the generalization of correlation factors and helps in improving the accuracy of the prediction for highly heterogeneous mixtures. The methodology also allows the analysis of mixtures for which the experimental approach is difficult, such as those including char particle, with the only requirement of carefully measuring the physical properties of the particles.
