Fluidized Bed Combustion | Types and Advantages

2019-7-21·The evaporator tubes of boiler are directly immersed in the fluidized bed and the tubes, being in direct contact with the burning coal particles, produce very high heat transfer rates. Because of this, the unit size is reduced to a great extent, and also produces combustion with very high efficiency. Types of Fluidized Bed Combustion (FBC)

Progress of circulating fluidized bed combustion

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.
