Operating Experience of Circulating Fluidized Bed

2016-4-20 · decision for a semi-dry spray dryer absorption (SDA) and a circulating fluidized bed (CFB) FGD-process. The main advantages of these technologies are up to 30% less water consumption, compared to a wet FGD (WFGD), the high removal efficiencies in particular SO2, SO3 and H2SO4, the assured product utilisation for landfill at the nearby opencast coal

Oxygen Carrier Aided Combustion (OCAC) of Wood

Oxygen Carrier Aided Combustion (OCAC) is realized by using an active oxygen-carrying bed material in fluidized bed boilers. The active material is reduced in fuel rich parts of the boiler and oxidized in air rich parts. Advantages could be achieved such as new mechanisms for oxygen transport in space and time. Here calcined manganese ore has been used as active bed material in a 12 MWth
