Abstract
When a bed of solid particles is subjected to an upward fluid flow above a critical velocity called the minimum fluidization velocity, the bed becomes fluid-like in a number of respects and is said to be fluidized. Because of the very large surface area, heat and mass exchange between the fluid and the solids are extremely efficient. In the case of typical gas fluidized beds, the solids also possess large mean and fluctuating velocities, thus promoting solids mixing and facilitating the addition and removal of the solids. These conditions favor the use of fluidized beds as chemical reactors, including as a special case combustors for solid, liquid, and gaseous fuels. Furthermore, the intense solids motion enhances heat exchange between the solids and immersed surfaces, permitting direct heat removal at low temperature drop using immersed heat-exchange tubes. Fluidized beds are also used in various configurations as heat exchangers. These and many other applications can be found in standard references (Kunii and Levenspiel, 1969; Davidson and Harrison, 1971; Kunii and Toei, 1983).
