  2. 11. Fuel dispersion and bubble distribution in fluidized beds

    Author : Johanna Olsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Fluidized bed technology is used for thermal conversion of solid fuels (combustion and gasification) and is especially suitable for conversion of low-rank fuels such as biomass and waste. The performance of fluidized bed units depends on the fuel mixing and fuel-gas contact. READ MORE

  4. 12. A Numerical Study of the Fluid Dynamics of Bubbling Fluidized Beds

    Author : Hans Enwald; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; validation; two-phase solver; multiblock; statistical bubble parameters; parallelization; bed expansion ratio; bubbling fluidized bed; two-fluid model;

    Abstract : The two-fluid model was evaluated as a tool for predicting local flow behaviour in bubbling fluidized beds. A review is given of the two-fluid model approach for simulation of the flow in bubbling fluidized beds. READ MORE

  6. 14. Fluidized bed combustion - modeling and mixing

    Author : David Pallarès; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluidized bed combustion; Mixing; Modeling;

    Abstract : 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. READ MORE

  7. 15. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study

    Author : Liang Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airflow; Wurster; coating; CFD; particle; Fluidized bed; drying; PEPT; spray; DEM;

    Abstract : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique. READ MORE
