Hydrodynamics stydy of conventionl (cylindrical) fluidized bed at ambient temperature.

Mohanta , Yayati Kishore (2013) Hydrodynamics stydy of conventionl (cylindrical) fluidized bed at ambient temperature. BTech thesis.



Now a days , the fluidized bed has got an vital application in the industial world . It is very much necessary to have the idea about the particle shape, type of distributor , minimum fluidization velocity, voidage , sphericity of particle etc in order to achieve the proper functioning of fluidized beds. In this present work, hydrodynamic of fluidized bed with regular particles was studied. The hydrodynamic behavior like pressure drop, minimum fluidization velocity accounting with different parameters were determined and they compared with the theoretical value. The present work is been focussed on understanding the hydrodynamic behaviour in a gas-solid two phase fluidized bed.Hematite powder of size 10 micrometer , sand particle ranging from 0.2 mm to 0.73 mm and dolomite particle from 0.03mm to 0.53mm are used as the solid phase. The fluidization operation had been carried out with air as gas phase and the hematite powder, sand and dolomite in the fluidizing cylinder . Superficial velocity of gas has been varied in the range of 0 to 0.8 m/s . The static bed heights of the solid phase in the fluidized bed used are taken from 2cm to 8.5 cm.
