The effect of gas velocity, solids flux and particle size on mass transfer coefficient was studied. From the experimental results a correlation has been proposed in terms of dimensionless parameters. %Z cited By 1; Conference of 9th International Conference on Circulating Fluidized Beds, CFB 2008, in Conjunction with the 4th International VGB Workshop on Operating Experience with Fluidized Bed Firing Systems ; Conference Date: 13 May 2008 Through 16 May 2008; Conference Code:106582
