    Sammanfattning : 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. LÄS MER

  4. 8. Thermally homogenous gasification of biomass/coal/waste for medium or high calorific value syngas production

    Författare :Anna Ponzio; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning :  Today’s problems with emissions of green house gases, land filling of waste and depletion of the oil reserves calls for new energy systems based on alternative fuels like biomass and waste. Gasification is an attractive technology for the use of such solid fuels. LÄS MER

  5. 9. Thermodynamic aspects and heat transfer characteristics of HiTAC furnaces with regenerators

    Författare :Nabil Rafidi; Wlodzimierz Blasiak; John Witton; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; flameless; oxy-fuel; heat-recirculation; gas-recirculation; heat transfer; furnace; radiant-tube; regenerative burner; honeycomb; fixed-bed; Thermal energy engineering; Termisk energiteknik;

    Sammanfattning : Oxygen-diluted Combustion (OdC) technology has evolved from the concept of Excess Enthalpy Combustion and is characterized by reactants of low oxygen concentration and high temperature. Recent advances in this technology have demonstrated significant energy savings, high and uniform thermal field, low pollution, and the possibility for downsizing the equipment for a range of furnace applications.
