Pressure Drop in Liquid-Solid Circulating Fluidized Beds
نویسندگان
چکیده
An experiment was conducted to obtain data of pressure drop in riser tubes of liquid-solid circulating fluidized beds. In the experiment, 2 kinds of riser tube having a diameter of 24mm and 36mm were used. Tested particles were of glass and ceramics, and their diameter range was from 2.10 to 4.95mm. Water at ambient conditions was used as the fluidizing fluid. Pressure drop in riser tubes was measured using a reversed U-tube manometer. Based on the experimental data, a calculation method was derived for predicting the pressure drop in riser tubes, which could reproduce almost all data with an accuracy of 20%. Furthermore, the effect of independent parameters was investigated on the pressure drop component ratios consisting the total pressure drop.

ISSN 2277 5056 | © 2012 Bonfring Abstract--Fluidization is an operation in which solid particles are kept under suspension supported by the upward flow of liquid/gas phase. In classic fluidization the solids density are higher than the liquid, where as in Inverse fluidization the solids density are lower than that of continuous liquid phase. The phase holdup measurements in three phase classic/...

In the present work an attempt has been made to study the effect of the twisted tapes as bed internals, on the performance of the gas-solid fluidized beds. Experimental investigation has been carried out in cylindrical column with and without twisted tapes. Twelve numbers of twisted tapes of three different widths with four values of the twist ratios for each width were studied at different...

متن کاملHeat Transfer of Liquid/ Solid Fluidized Beds for Newtonian and Non-Newtonian Fluids
The excellent performance of fluidized bed heat exchangers is due to the interaction between particles and heat transfer surface and to the mixing effects in the viscous sublayer. In this paper, the results of experimental investigations on heat transfer for a wide range of Newtonian and non-Newtonian (shear-thinning power law) fluids are presented. New design equations have been developed ...
متن کاملCluster Dynamics in a Circulating Fluidized Bed
A common hydrodynamic feature in industrial scale circulating fluidized beds is the presence of clusters. The continuous formation and destruction of clusters strongly influences particle hold-up, pressure drop, heat transfer at the wall, and mixing. In this paper fiber optic data is analyzed using discrete wavelet analysis to characterize the dynamic behavior of clusters. Five radial positions...
