10.6.1 Fluidized Bed Furnace Heat Transfer. We often discuss the lower furnace and upper furnace heat transfer separately. As the lower furnace has refractory, the furnace heat transfer correlations often apply only to the upper furnace. The fluidized bed is always dynamic and the suspension density varies as regions with hardly any solids alternate with regions with a higher suspension. Examples are …

Fluidized Bed Boiler - an overview | ScienceDirect Topics

In fluidized-bed boilers a bed, usually consisting of sand particles, is brought into a fluidized state by primary air supplied from below the bed. Solid fuel added to the bed will burn in the oxygen-rich conditions inside the bed created by the primary air.

Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the …

Fluidized Bed Combustion takes place when the forced draught fan supplies air to the Furnace of the Boiler. In the furnace, and is (used for Bubbling phenomenon) placed on the Bed and is heated before fluidization, the air enters the bed from the nozzles fitted on the Furnace Bed.

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 …

Fluidized bed combustion (FBC) FBCs are smaller than the equivalent conventional furnace, so may offer significant advantages over the latter in terms of cost and flexibility. FBC reduces the amount of sulfur emitted in the form of SO x emissions. Limestone is used to precipitate out sulfate during combustion, which also allows more efficient heat transfer from the boiler to the apparatus used to …
