Hydrodynamics of Bubbling Fluidized Beds at High Temperature

The catalytic reaction process in fluidized beds, the coal combustion and gasification in the bed, and other various industrial processes all involve high temperature operation. It focuses on reviewing the effect of temperature on the minimum fluidization velocity, minimum fluidization voidage, bed expansion ratio, and bubble diameter, which are in relation with the design and operation of fluidized beds. Based on experimental findings and theory research of author and other researchers, some suggestions are proposed on the fundamental studies at the high temperature fluidized beds.
