460-ton cycle fluidized bed boiler work principle

Principles of Fluidized Bed Combustion Operation

Principles of Fluidized Bed Combustion Operation: A fluidized bed is composed of fuel (coal coke biomass etc.) and bed material (ash sand and/or sorbent) contained within an atmospheric or pressurized vessel. The bed becomes . fluidized when air or other gas flows upward at a velocity sufficient to expand the .

Fluidized Bed Boiler - an overview | ScienceDirect Topics

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 13 m s 1 at 800900 °C.
