Fluidized Bed Boiler - an overview | ScienceDirect Topics

The circulating fluidized bed boiler (CFB boiler) is the second-generation fluidized bed boiler, the updated version of the bubbling fluidized bed boiler (BFB boiler). In this chapter, fundamental concepts of fluidized beds (including the definition and characteristics of “fluidized bed,” basic CFB boiler structure, several types of CFB boilers, and notable characteristics of CFB boilers) are introduced. After that, convective …

Fluidized Bed Combustion (FBC Boiler) “Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.”. A bed of solid particles is said to be fluidized when the pressurized fluid (liquid or gas) is passed through the medium and causes the solid particles to behave like a fluid under certain conditions.. Fluidization causes the transformation of the state of solid particles from static to dynamic.

04-03-2020 · Fluidization is a method of mixing fuel and air in a specific proportion, for obtaining combustion. A fluidized bed may be defined as the bed of solid particles behaving as a fluid.It operates on the principal that when an evenly distributed air is passed upward through a finely divided bed of solid particles at low velocity, the particles remain undisturbed, but if the velocity of air flow is steadily …

In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand. With further increase in the velocity, the air bubbles through the bed and the particles attain a state of high turbulence. Under such conditions, the bed assumes the …

Boiler engineers can choose between two main types of fluidized-bed boilers—bubbling fluidized bed (BFB) and circulating fluidized bed (CFB). In BFB boilers the velocity of the combustion air is low enough that the fluidized particles remain in the lower furnace; in a CFB unit the velocity is greater and hot particles are circulated through the entire range of the boiler combustion zone. The fuel is in contact …
