Bubbling Fluidized-Bed Boilers - Babcock & Wilcox

The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed, that is, 1–3 m s −1 at 800–900 °C.

Fluidized Bed Combustors for Biomass Boilers - ASME

Jun 14, 2018 · " (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 - Wikipedia

A circulating fluidized bed (CFB) boiler features higher gas velocity (superficial flow velocity) in the furnace (combustor) compared with a bubbling fluidized bed (BFB) boiler. The boiler activates a mixture of particles and gas to improve combustion reaction.
