   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized bed combustion; Mixing; Modeling;

   Sammanfattning : First demonstrated on industrial scale in 1976, fluidized bed combustion (FBC) rapidly became an established technology for solid fuel combustion with a currentinstalled capacity of about 30 GWe and power plants ranging from 10 to 460 MWe.The widespread use of the FBC technology both under so-called circulating and bubbling conditions (i.e. LÄS MER

3. 2. Macroscopic modeling of fluid dynamics in large-scale circultaing fluidized beds

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel mixing; fluid dynamics; large-scale circulating fluidized bed; particle tracking;

   Sammanfattning : Satisfactory knowledge of the fluid dynamics governing the gas-solid flow in large-scaleCirculating Fluidized Bed (CFB) units is still lacking, although the CFB technology is widelyused for power (and heat) generation. Due to the complex two-phase flow in large CFB unitsfluid dynamical modeling of practical use is so far limited to a macroscopic approach andavailable models generally focus in describing one of the following key-phenomena: maingas-solid flow pattern, mixing of fuel particles and gas mixing.
