Course Description

This 5 day course focuses on the design and operation of fluidized beds in many different industrial processes, emphasizing the rationale for choosing fluidized beds for each particular process. It presents both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of  operating processes  that use fluid bed reactors. 

This course is designed to provide participants with a detailed and an up-to-date overview of fluidized bed reactor startup, operation and troubleshooting. It covers the catalytic processes; the non-catalytic processes, combustion, gasification and chemical looping; the fluidized-bed-combustion; the conversion of biomass and waste fuels in fluidized-bed reactors; the conversion mechanisms in fluidized-bed reactors; and the operating parameters comprising of feeding methods, equivalence ratio, number of feed points, bed temperature, solid fuel feed size, effects of inserts content, bed depth and fluidizing velocity.

During this interactive course, participants will learn the various examples of industrial applications for fluidized-bed combustion and gasification, pyrolysis and fluid bed plasma treatment; the effects of process conditions on fluidization, the effect of temperature fluidization and the effect of pressure on fluidization; and the fluidized-bed scaling, dimensional analysis, combustion scaling and validation of the scaling laws.
