    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.
