  2. 1. Design and experimental studies of a biomass fired furnace for small- and medium scale heating applications

    Author : Joakim Lundgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : The main objective of the work was to develop a biomass fired furnace for small and medium scale heating systems, which has the ability to manage wet as well as unclassified biofuels with maintained low emissions of harmful substances. The system should also be able to cope with large and frequently occurring thermal output variations fulfilling rigorous environmental restrictions. READ MORE

  4. 2. 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

  5. 3. A small scale wastewater treatment system adapted to nutrient recovery in cold climate : performance and possible sorbents

    Author : Lea Rastas Amofah; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Waterbodies are impaired by, among other things, discharge from onsite small- scale wastewater (WW) treatment systems. Hence, these systems need to be updated to improve the effluent quality and the reuse of nutrients within society. READ MORE

  6. 4. Reactive filter materials for ammonium and phosphorus sorption in small scale wastewater treatment

    Author : Annelie Hedström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Existing small scale wastewater treatment systems in Nordic countries have generally low treatment efficiency regarding phosphorus and nitrogen. Even though only 15% of the Swedish population is connected to on-site wastewater treatment systems, the total discharge of phosphorus from these systems exceeds the total discharge from all municipal treatment plants in Sweden.

  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
