Studies on circulating fluidized bed (CFB) boilers have being conducted at the Tsinghua University (TH) for about two decades and much of works are done to link the fundamentals with practical application. A full set of design theory was developed and some key elements of this theory are presented in this paper.

2013-10-24 · circulating fluidized-bed boilers involves a two-stage combustion process: the reducing combustion at the fluidized-bed section, and the oxidizing combustion at the freeboard section. Next, the unburned carbon is collected by a high-temperature cyclone located at the boiler exit to recycle to the boiler, thus increasing the denitration efficiency.

These boilers are termed as „Circulating Fluidized Bed Combustion Boilersâ  [CFBC]. Basu and Fraser [5] have defined the CFBC boiler as follows: "A circulating fluidized bed boiler is a device for generating steam by burning fossil fuels or biomass in a combustion chamber operated under special hydrodynamic condition.

Circulating (fast )fluidized bed combustion system are designed to overcome drawbacks associated with AFBC boiler. Fluidizing velocity in this type of boiler is relatively very high 3.7-9m/sec, The combustion takes place at 840-900 °C, and the fine particles (<450 microns) are elutriated out of the furnace with flue gas velocity of 4–6 m/s.
