Fluidisation is a phenomenon whereby solid particulate is placed under certain conditions to cause it to behave like a fluid. A fluidized bed is a system conceived to facilitate the fluidisation. Fluidized beds have a wide range of applications including but not limited to: assisting with chemical reactions, heat transfer, mixing and drying. A recent concept devised and patented by Outotec, "An annular fluidized bed consists of a large central nozzle surrounded be a stationary fluidized" .
