Fluidized Bed Combustion FBC Boiler - Boilersin

" (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers." In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.

Progress of circulating fluidized bed combustio

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.
