Fluidized bed combustion - Wikipedia

Fluidized Bed Combustion. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal. Jets of air suspend the mixture of sorbent and burning coal during combustion, converting the mixture into a suspension of red-hot particles that flow like a fluid. These boilers operate at atmospheric pressure.

The High temperature high pressure CFB boiler is a more advanced fluidized bed boiler technology. CFB boilers have higher fluidizing air velocities ranging from 10 to 20 ft/sec, lack a distinct transition from the dense bed at the bottom of the furnace to the dilute zone above, and have a very high flow rate of re-circulated solids.
