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.
