  2. 1. Improving Wood Fuel Pellets for Household Use : Perspectives on Quality, Efficiency and Environment

    Author : Magnus Ståhl; Bengt Månsson; Johan Vinterbäck; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; quality; efficency; environment; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Bioenergy is one of many contributors to reducing the use of fossil fuels in order to mitigate climate change by decreasing CO2-emissions, and the potential for biofuels are large. The wood fuel pellets are a refined biofuel made of sawdust, which is dried and compressed to achieve improved fuel and transportation properties. READ MORE

  4. 2. Implication of pellet quality on combustion performance

    Author : Peter Sundberg; Claes Tullin; Sylvia Larsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Quality aspects of wood pellets and their use have been of utmost importance since the development of the pellet market in the early 1980s. Research and hard-earned knowledge have resulted in advancements in the field, but there are still uncertainties in the pellet industry about how different quality aspects affect combustion performance.

  5. 3. Characterisation of Muko iron ores (Uganda( for defferent routes of iron production

    Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron ore; iron; characterization; physical and metallurgical properties; sinter; pellet; blast furnace; direct reduction; Muko; Uganda; Materials science; Teknisk materialvetenskap; SRA - Production; SRA - Produktion;

    Abstract : Iron and its products, especially the various forms of steel, have been and still are a vital material in many sectors of life. It is utilized in many industrial activities ranging from production of heavy duty mechanical equipment to light electrical appliances and home appliances. With the world‟s iron ore consumption estimated to stand at 1. READ MORE

  6. 4. Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

    Author : Julia Wolska; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Feed; Physical quality; Durability; Aging; Crosslinking; Transglutaminase;

    Abstract : As aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. READ MORE

  7. 5. Influence of Oxygen Enrichment on the Oxidation of a Magnetite Pellet Bed During Pot Furnace Induration

    Author : Anna Eriksson; Charlotte Andersson; Hesham Ahmed; Timo Fabritius; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen enrichment; Magnetite pellet bed; Oxidation; Pot furnace; Induration; Fossil-free ironmaking; Process Metallurgy; Processmetallurgi;

    Abstract : This study was motivated by the excess oxygen that likely results from the current transition to hydrogen-based Swedish steel production. The potential usability of large amounts of oxygen in a process gas for iron ore pellet induration could improve the process efficiency in terms of fuel consumption and productivity. READ MORE
