  3. 2. Wood Fuel Pellets: Sawdust Drying in the Energy System

    Författare :Magnus Ståhl; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; VOC; system integration; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : In 2004, the amount of wood fuel pellets used in Sweden was 1 256 000 tons, it was mostly used in large scale burning for district heating. Over the last 10 years, a significant increase in pellet production has occurred and today the preferred raw materials for pellet production, i.e., dry sawdust and wood shavings, are insufficient.

  4. 3. Influence of peat addition to biomass pellets on combustion characteristics in residential appliances

    Författare :Ida-Linn Näzelius; Markus Broström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : The biomass pellet consumption, both in the industry and in residential appliances, has increased during the latest years and this is expected to continue. In order to handle the demand, more ash rich (>0,5 wt-%) raw materials have been introduced as energy wood and other forest based fuels. LÄS MER

  5. 4. NOx Formation in Rotary Kilns for Iron Ore Pelletization

    Författare :Rikard Edland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; combustion chemistry; emissions control; Grate-Kiln process; Nitrogen oxides; NOx formation;

    Sammanfattning : The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. LÄS MER

  7. 5. Degradation mechanisms in refractory lining materials of rotary kilns for iron ore pellet production

    Författare :Jesper Stjernberg; Marc Huger; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Sammanfattning : Iron is one of the most important resources in the lithosphere; 90% of all metal ores extracted are based on iron. Many steps are included in the extraction of iron from ore, with extraction processes varying among different producers. Iron ore pellets are a prepared burden material for ironmaking in the blast furnace or by direct reduction. LÄS MER
