Fluidized Bed Boiler - an overview | ScienceDirect Topics

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006

Fluidized Bed Combustion FBC Boiler - Boilersinfo

“ (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers.” 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.

Fluidized Bed Combustion. Fluidized bed combustion (FBC) is a well-established commercial combustion technology, in which combustion occurs in the presence of high concentrations of solids, typically sand, ash or that derived from limestone, if in-situ sulphur capture is required (i.e., a bed), which are fluidized in a stream of combustion air.
