Analysis of Changes on Mean Particle Size in a Fluidized Bed using Vibration Signature
Vibration signals were measured in a lab-scale fluidized bed to investigate the changes in particle sizes. Experiments were carried out in the bed with a different mass fraction of coarser particles at different superficial gas velocities, and probe heights. The S-statistic test evaluates the dimensionless squared distance between two attractors reconstructed from time series of vibration signa...

15 صفحه اولEffect of Segregation on the Reaction Rate of Sewage Sludge Pyrolysis in a Bubbling Fluidized Bed
The evolution of the pyrolysis of sewage sludge in a fixed and a fluidized bed was analyzed using a novel measuring technique. This original measuring technique consists of installing the whole reactor over a precision scale, capable of measuring the mass of the complete reactor with enough precision to detect the mass released by the sewage sludge sample during its pyrolysis. The inert conditi...
متن کاملX-ray tomography of a fluidized bed Effect of pressure and fines on bubbles in a fluidized bed
Using a fast X-ray tomography setup measurements have been done on a 25 cm diameter f luidized bed of Geldart B pow^der and a 24 cm bed of Geldart A powder. The average bubble sizes have been determined over a measurement period of 60 seconds. The resolution of this setup is about 4.5 m m per pixel at a rate of 250 reconstructions per second. I t is possible to detect bubbles as small as 2.5 cm...
متن کاملControl of a Fluidized Bed Polyethylene Reactor
In present paper, dynamic behavior and control of a fluidized bed reactor for polyethylene production has been considered. A double active sites model for Ziegler-Natta catalysts is used for simulation of polymerization reaction. Hydrodynamic behavior of the bed is modeled using a two phase model including bubble and emulsion phases in which bubble phase has plug flow pattern with different...
