Circulating fluidized bed Wikipedia

Fluidization is the phenomenon by which solid particles are transported into a fluid-like state through suspension in a gas or liquid. The resultant mixing of gas and solids promotes rapid heat transfer and chemical reactions within the bed. Power plants that use this technology are capable of burning low grade fuels at high efficiency and without the need for expensive fuel preparation.
