Fluidized bed combustion (FBC) provides several advantages for burning solid fuels, including higher efficiency, lower emissions, and the ability to burn low quality (e.g. high moisture) fuels. This course will focus on the operation of bubbling and circulating fluidized bed boilers.
A circulating bed usually has a superficial velocity greater than 13 ft./sec. and has a reinjection/recycle ratio greater than 5. Compared to a bubbling bed, a circulating bed has significantly higher solids concentration throughout the combustor. 2 - Bubbling fluidized bed (BFB) - an FBC with a definite region between the relatively dense
Circulating fluidized bed technologies are characterized by unequaled fuel flexibility, high efficiency, and the ability to employ a diversity of fuels, including fuels which are difficult to burn.
