  2. 1. CFD in the design of gas quenching furnace

    Author : Olivier Macchion; Said Zahrai; Bengt Sunden; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Gas quenching; modeling; CFD; gas mixtures; uniformity.; Numerisk analys; Numerical analysis; Numerisk analys;

    Abstract : This thesis focuses on the numerical and theoretical studies of gas quenching in industrial furnaces. Gas quenching is the rapid cooling of metal pieces, aiming at forcing a phase transformation of the metal structure to improve its mechanical properties. READ MORE

  5. 3. Sustainable Energy Conversion from Biomass Waste Combustion - Experimental and Multiscale Modelling Studies

    Author : Maulana Nugraha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; particulate matter; biomass; combustion; soot; furnace; orthogonal collocation; CFD simulation;

    Abstract : The development of sustainable energy conversion via residual biomass combustion is one of the scientific and industrial community focus today to fulfilling the global net zero emission commitment in 2050. Despite its potency due to the abundant stock of biomass, hazardous particulate matter (PM) emission from residual biomass combustion remains a big challenge to increase the contribution of biomass combustion as a main renewable energy source.

  6. 4. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

    Author : Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

  7. 5. Disturbances in Fixed-Bed Combustion

    Author : Sven Hermansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; modelling; packed bed; bed; combustion; channelling; grate furnace;

    Abstract : Conversion of solid fuels in fixed beds is a common method for heat and power production. A frequent fixed-bed technique in small to medium scale is combustion in grate furnaces. Grate furnaces are widely used in the industrial energy branch and appreciated for their stability and simplicity of control. READ MORE
