Jan 1, 2013 · The Ahlstom Pyropower circulating fluidized bed (CFB) was developed in the late 1970s. Since 1969, CFB research had been one of the major research and development projects of the Hans Ahlstrom Laboratory in Karhula, Finland. Further investigation of CFB technology was initiated in the mid-1970s.

Jun 21, 2024 · The most significant introduction of fluidized bed combustion technology took place about 50 years ago. Initially the combustion beds were of the bubbling type. Once the designs had reached commercial application, several drawbacks were discovered: Erosion on in-bed heat-exchanger tubes, insufficient combustion and desulphurization efficiencies with coal, unfavourable scale-up to electric ...
Fluidized-bed combustion (FBC) system is a variation of PCC technology, in which coal is burned with air circulating through a bed of broken fuel mixed with an inert material. FBC systems have high fuel flexibility and can operate with different types of coal, biomass, or even low-grade fuels, such as petroleum coke.
Circulating fluidized bed (CFB) technology has been recognized by industry as a viable gas/solid contacting process with applications including combustion for power generation and waste incineration, pyrolysis, calcining, and catalysis. One important and growing use of circulating fluidized beds is as utility boilers.

Nov 3, 2009 · Gas−particle two-phase turbulent flows are numerically studied in a 50 MWe circulating fluidized bed combustor. The dense flow of particles is modeled by the frictional stress models adopted from solid mechanics theory, and the dilute flow in the so-called rapid granular flow regime is modeled from the kinetic theory of granular flow. At low concentrations the viscosity due to the effect of ...
