  1. 1. Fluidized Bed Operating Parameters and Eulerian Erosion Models

    Författare :Mattias Gustavsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Eulerian erosion model; fluidized bed; distributor plate; slugging; plenum chamber; brittle; two-fluid model; ductile; air-feed system;

    Sammanfattning : A numerical two-fluid code, Gemini 2D, was adapted to study gas-solid fluidization in arbitrary 2D domains. The code was also used to study fluid dynamic mechanisms of dense particle flow that cause ductile and brittle erosion of solids. LÄS MER

  4. 3. Fluid Dynamics of the Bottom Bed of Circulating Fluidized Bed Boilers

    Författare :Anders Svensson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Design, modelling and operation of a 100 kW chemical-looping combustor for solid fuels

    Författare :Pontus Markström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Fluidised beds; Chemical-looping combustion; Modelling; Carbon capture and storage; Oxygen carriers;

    Sammanfattning : With the increasing threat of global warming, technologies for efficient capture and storage of the greenhouse gas CO2 are sought after. Chemical-looping combustion is a novel CO2 capture technology that can be applied when burning gaseous, liquid or solid fuels. LÄS MER
