  1. 1. Fluidized bed combustion - modeling and mixing

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

    Sammanfattning : 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. LÄS MER

  4. 3. The effects of mixing on the enzymatic hydrolysis of lignocellulosic biomass

    Författare :Adnan Kadic; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; softwood; spruce; enzymatic hydrolysis; mixing; viscosity;

    Sammanfattning : Biorefining of lignocellulosic biomass into biofuels and chemicals can help replace fossil resources and decrease anthropogenic greenhouse gas emissions. This thesis is focused on the effects of mixing on the enzymatic hydrolysis of pretreated biomass. LÄS MER

  5. 4. Flow structures in solid-liquid suspensions in mixing and confined jets

    Författare :Matthias Eng; Chalmers tekniska högskola; []

    Sammanfattning : This thesis investigates the influence of solid particles on different liquid flow systems.Large-scale periodic fluctuations such as macro instability (MI) phenomena in a mixingvessel and jet flows in a confined jet were experimentally analyzed by means of LDV. Theinfluences of different sized (0.5mm-2mm) glass particles (0%vol - 6. LÄS MER

  7. 5. SOLIDS MIXING IN BUBBLING FLUIDIZED BEDS

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

    Sammanfattning : 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. LÄS MER
