  • Optimized Combustion Through Collaboration of Boiler and

    2. Fluidized Bed Boiler Fluidized bed boilers can be categorized in two main types: bubbling (BFB) and circulating (CFB) boilers. They have a lot of similarities, however, the biggest difference being that in a CFB boiler, the sand bed is not still but circulating through cyclones in the boiler. As a result,Learn More

  • Advanced biofuel production via gasification – lessons

    Feb 21, 2018 · Starting from the CFB boiler, the recirculation of the bed material separated in the cyclone is directed to the BFB boiler instead of directly back to the combustion chamber (as is the case when the CFB boiler is operated as a boiler rather than as one of the interconnected reactors in a DFB gasifier).Learn More

  • Progress of circulating fluidized bed combustion

    By 2016, over 3000 CFB boilers were in commercial operation with a total installed capacity of over 90000 MW among which over 100 units are 300 MW. China started research on bubbling fluidized bed (BFB) in the 1960s. A series of BFB boilers with small capacities of 4–130 t/h steam were developed and the theory of BFB boiler design was Learn More

  • NOx Emission from a Circulating Fluidized Bed Boiler

    Aug 13, 2012 · The NOx emission from a circulating fluidized bed (CFB) boiler with 50 MW rated thermal output (50 MWth) during the cofiring of anthracite coal and pelletized corn stalk biomass was investigated. Cofiring could improve combustion efficiency and, thus, the thermal efficiency of the boiler.
