  2. 11. Drying of iron ore pellets : analysis with CFD

    Author : Anna-Lena Ljung; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. READ MORE

  4. 12. Energy Efficient Wood Fuel Drying

    Author : Roger Renström; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : With reference to the reduction of carbon dioxide emissions, biofuel is pointed out as an important substitute for fossil fuels. The Swedish Government favours the use of biofuel by imposing taxes on fossil fuels. READ MORE

  5. 13. Mathematical modeling of municipal solid waste plasma gasification in a fixed-bed melting reactor

    Author : Qinglin Zhang; Weihong Yang; Wlodzimierz Blasiak; Halina Kruczek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; plasma gasification; municipal solid waste; fixed-bed;

    Abstract : The increasing yield of municipal solid waste (MSW) is one of the main by-products of modern society. Among various MSW treatment methods, plasma gasification in a fixed-bed melting reactor (PGM) is a new technology, which may provide an efficient and environmental friendly solution for problems related to MSW disposals.

  6. 14. Modeling drying of iron ore pellets

    Author : Anna-Lena Ljung; Graham Nathan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Iron ore pellets are a highly refined product supplied to the steel making industry for use in blast furnaces or direct reduction processes. The use of pellets offers many advantages such as customer adopted products, transportability and mechanical strength yet the production is time and energy consuming. READ MORE

  7. 15. Heat Balance Modeling of a Stationary Fluidized-Bed Furnace Burning Biomass

    Author : Fredrik Niklasson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing; modeling; biomass; dispersion; heat balance; fluidized bed boiler;

    Abstract : The influence of biomass fuel properties on the heat balance of the bottom region (bed and splash zone) of a commercial-scale bubbling fluidized-bed furnace is investigated theoretically and experimentally. The experiments have been carried out at the Chalmers 12 MWth research boiler, operated under non-circulating conditions during most of the experiments. READ MORE
