  2. 1. Mixing of Large Solids in Fluidized Beds

    Author : Anna Köhler; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel mixing; fluidized beds; magnetic particle tracking; drag; semiempirical modelling; fluid-dynamic downscaling;

    Abstract : Fluidization is a technology that is widely used in systems in which particulate solids are to be transported, mixed, and/or reacted with gases. In fluidized bed applications, the lateral mixing rate of the solids and the heat and mass transfer with their surroundings play important roles in process performance. READ MORE

  4. 2. Lateral mixing of solids in bubbling fluidized beds – experimental quantification

    Author : Erik Sette; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solids cross-flow; lateral dispersion; Solids mixing; fluid-dynamic scaling;

    Abstract : For solid fuels, thermochemical conversion processes such as combustion and gasification are especially suitable to be carried out in fluidized bed units because of the relatively high mixing rates, fuel flexibility and the possibility to use active bed material to enhance process efficiency. Fuels such as biomass and waste, which are commonly used in fluidized beds, are characterized by volatile contents much higher than what is found in fossil fuels such as coal. READ MORE

  5. 3. SOLIDS MIXING IN BUBBLING FLUIDIZED BEDS

    Author : Erik Sette; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-dynamic scaling; Solids mixing; lateral dispersion; solids cross-flow;

    Abstract : For solid fuels, thermochemical conversion processes such as combustion and gasification are especially suitable to be carried out in fluidized bed units because of the relatively high mixing rates, fuel flexibility and the possibility to use active bed material to enhance process efficiency. Mixing of fuel is important to ensure complete conversion and reduced emissions of unburnt material. READ MORE
