High-density circulating fluidized bed (HDCFB) and circulating turbulent fluidized bed (CTFB) have many advantages comparing to the conventional circulating fluidized bed. This paper introduces HDCFB and CTFB from such aspects, as experimental facilities, operating principles, flow structures and comparisons with other flow regimes. In HDCFB and CTFB, one could obtain high solids concentration, high heat and mass transfer efficiency, high gas and solids contacting efficiency, less solids backmixing, and more uniform flow structure. As such, high production efficiency and better product quality can be achieved, which is very important for industrial applications. Comparing HDCFB and CTFB, CTFB has more advantages and better industrial applications.
