GOMEZ, CARLOS  and  LOPERA, ELIANA. EXPERIMENTAL EVALUATIONOF THEMINIMUMFLUIDIZATIONVELOCITIESFOR MIXTURESOFCOLOMBIAN RESIDUAL COAL AND AGRICULTURAL WASTES. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.169, pp.105-112. ISSN 0012-7353.

A systematic experimental study is conducted to determine fluid dynamic properties such as the particle size distribution, bulk density, fluidizing velocity, etc.,of mixtures ofresidualcoal, a waste from the mining activity in Colombia, and agricultural wastes like rice husks, sawdust and coffee shells. From the results obtained in this study, optimal mixtures showing the best cold fluid dynamicswere recommended, for further evaluation in co-gasification process.

Keywords : Fluidized bed; coal-biomass mixtures; minimum fluidization velocity.
