Monitoring Fluidized Bed Dryer Hydrodynamics Using Pressure Fluctuations and Electrical Capacitance Tomography

Electrical Capacitance Tomography System

Electrical Capacitance Tomography is a non intruding technique used in industries. It is based on measuring the capacitance of multi-electrode ECT sensor produced by the change in dielectricity or due to change in concentration of material. With the use of computed values, a cross sectional image of the material placed in the dielectric medium is obtained. ECT system can be used in chemical fie...

Electrical Capacitance Tomography with a Square Sensor

Abstract – In the past, electrical capacitance tomography (ECT) with circular sensors has been extensively investigated. For some industrial applications such as circulating fluidised beds, square sensors are required. Research into this specific area has been carried out at UMIST for the first time. To generate sensitivity maps, the Laplace equation is solved using a finite difference method (...

X-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...
