May Combustion Chamber - an overview |

Also, existing coal-fired FBCs can be easily adapted to cofiring. There are two major types of FBC systems: bubbling fluidized bed combustors and circulating fluidized bed combustors (Fig. 5.5). In general, fluidized bed boilers can substitute higher levels of coal with biomass than pulverized coal-fired or grate-fired boilers.

Fluidized bed - Thermopedia

The fluidized state, occuring between the filtration of the fixed bed and the pneumatic conveying regime, includes three different regimes: stationary bubbling fluidized bed, turbulent fluidized bed and the regime of fast fluidization. Recently, many technological processes are being carried out in the last two of the above mentioned regimes.
