Fluidised bed combustion (FBC)

Fluidized bed combustion technologies include:

  • atmospheric pressure fluidized bed combustion (FBC) in both bubbling (BFBC) and circulating (CFBC) beds, mainly with subcritical steam turbines, together with sorbent injection for SO2 reduction and particulates removal from flue gases;
  • pressurized fluidized bed combustion (PFBC) mainly using bubbling beds, and in combined cycle with both a gas and steam turbine. Sorbent injection is used for SO2 reduction and particulates removal from flue gases. Pressurized circulating fluidized bed combustion (PCFBC) is being demonstrated;.
