    1. Features of the Tonghae CFB Boiler and Operation Con-ditions The Tonghae CFB boiler, which has been described in many pre-vious studies, is shown in Fig.1 [4,5]. It consists of a furnace (19m-W ×8m-L×32 m-H), three cyclones and loopseals, three fluidized bed heat exchangers (FBHEs) and a fluidized bed ash cooler (FBAC).Get Price

  • Fluidized bed combustion - Wikipedia

    The circulating fluidized bed (CFB) boiler (see Figure 8) takes the principle of the bubbling bed one step further and with increased fluidization velocity the particles are lifted out of the bed and follow the gas out of the combustion chamber. They are then separated from the gas in a cyclone or beam separator and returned to the bed.Get Price
