(In some cases air is heated by steam or water coil air heater and flue gas air pre-heater.) main primary air flow is led to a boiler windbox under the grid of the combustion chamber. It is used as the source of fluidizing air for the fluidizing bed of fuel and sorbent in the combustion chamber and supplies most (~55%) of the combustion air for the process.

The first lower energy consumption CFB boiler based on the re-specification of the fluidization state began commercial operational in 2007. As shown in Fig. 5, the field test results [] showed that with the pressure drop decrease from 7.3 to 3.2 kPa, the solid suspension density in the dilute zone was barely influenced due to the higher collection efficiency of the cyclones.
