Bed Management - Sumitomo SHI FW

In the BFB boiler the bottom of the furnace has a solid/gas suspension, known as a fluidized bed, which behaves like a liquid. In the CFB boiler, Fig. 1.8, there is no sharp decrease of solid particles but solids travel continuously from the dense bottom of the furnace to the top. The CFB furnace can be said to consist of a suspension of sand, ash, flue gas, and burning fuel at a fairly even temperature.
