Fluidized Bed Combustors for Biomass Boilers - ASME

Fluidized-bed boilers are the most common type of boiler recommended for biomass fuel, which is burned within a hot bed of inert particles, typically sand. The fuel-particle mix is suspended by an upward flow of combustion air within the bed. As velocities increase the gas/solid mix exhibits fluid-like properties.

Fluidized Temperature Baths | Accurate Thermal Systems

Fluidized Temperature Baths typically provide faster processing times than ovens and furnaces and are much more thermally stable and uniform. Fast heat up of immersed parts and objects is another major advantage. Fluidized baths are safer to operate than molten salt baths while immersed objects come out clean and dry with no material to remove.

Some Considerations Before Designing Your Own Fluidized ...

Fluidized bed filters consist of a vertical contact column in which water is pumped upward. Sand placed in the contact column is thus suspended by the upward flush of water. The trick is to supply a sufficiently rapid water flow to suspend the sand, but not so rapid that the sand is blown out of the top of the filter all together. The sand ...
