  2. 1. Fluid Dynamics of the Bottom Bed of Circulating Fluidized Bed Boilers

    Author : Anders Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidized beds; circulating fluidized bed boilers; fluctuations; fluidization regimes; bottom bed; bed porosity; fluid dynamics; bubbling beds; circulating fluidized beds; non-slugging; bed expansion; particle concentration;

    Abstract : The fluid dynamic conditions in the furnace of a fluidized bed boiler influence the combustion and the production of harmful emissions. A substantial amount of the bed material in a circulating fluidized bed (CFB) boiler is present as a dense bubbling bottom bed. READ MORE

  4. 2. 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

  6. 4. Moisture Buffering in the Indoor Environment

    Author : Kaisa Svennberg; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; furniture; textiles; moisture buffering; beds; indoor air; indoor environment; sorption isotherms; field measurements; definition scheme; Technological sciences;

    Abstract : Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g. READ MORE

  7. 5. Axial Mixing of Large Solids in Fluidised Beds – Modelling and Experiments

    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; fluid-dynamic down-scaling; fluidised beds; magnetic particle tracking; solids mixing; semi-empirical modelling;

    Abstract : Fluidisation is a technology commonly found wherever particulate solids are to be transported, mixed and/or reacted with a gas. At present, it is a widespread technology with applications ranging from the production of carbon nanotubes in the manufacturing industry to the conversion of solid fuels in the heat and power sector.
