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

    Författare :Anna Köhler; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Erosion - Corrosion Resistance and Adhesion of Laser and Thermally Deposited Coatings in Fluidised Beds

    Författare :Anders Hjörnhede; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; fluidised bed; HVOF; laser cladding; CFB; FBC; adhesion testing; PFBC; thermal spraying; arc spray; erosion - corrosion; acoustic emission;

    Sammanfattning : High temperature erosion - corrosion is the major source for degradation of components such as heat exchangers, tubes, cyclones and water walls used in Fluidised Bed Combustion (FBC) plants. By coating the exposed components with a protective material, the degradation rate can be decreased. LÄS MER

  5. 4. Fuel dispersion and bubble flow distribution in fluidized beds

    Författare :Johanna Olsson; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluidised bed; fuel mixing; bubble distribution; digital image analysis; particle tracking; Energi och material; Resource Recovery; Resursåtervinning;

    Sammanfattning : 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. LÄS MER

  7. 5. 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
