  1. 16. Slag formation in fixed bed combustion of phosphorus-poor biomass

    Författare :Ida-Linn Näzelius; Marcus Öhman; Bengt-Johan Skrifvars; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; slagging; fixed bed; Energiteknik; Energy Engineering;

    Sammanfattning : To handle a great demand for biomass, alternative biomasses beyond stem wood are being introduced into the solid fuel combustion market, fuels with generally higher (>0,5 wt-%) ash content and different fuel ash compositions compared to stem wood, such as forest residue, bark, grass and straw. Unfortunately, combustion of these alternative fuels often causes more ash related problems such as fouling, slagging and higher particle emissions compared to combustion of stem wood. LÄS MER

  3. 17. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst

    Författare :Hanmin Yang; Weihong Yang; Pär Jönsson; Linda Sandström; Chunfei Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic upgrading; Biomass; Biochar; Syngas; Hydrogen; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals. LÄS MER

  4. 18. Electrification of rural Mozambique : Sustainable energy solutions

    Författare :Miguel Meque Uamusse; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy; hydropower potential; Rural electrification; mini-grid; biomass; climate change effects;

    Sammanfattning : The UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. The effects on socioeconomic development by access to safe, affordable, and clean electricity stands out as educational benefits, income improvement, and health progress. LÄS MER

  5. 19. Materials and Coatings for Superheater Tubes in Biomass- and Waste-fired Boilers

    Författare :Vicent Ssenteza; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary Protection; Waste; Boiler; High-Temperature Corrosion; Phase transformation; Biomass; Breakaway Oxidation;

    Sammanfattning : Combustion of biomass and waste fuels has strong potential as an alternative renewable energy source for meeting the increasing global energy demand, while reducing the net release of CO2 into the atmosphere. The combustion of biomass and waste releases flue gases that contain high amount of alkali salts and water vapour, which drive the corrosion of metallic boiler components. LÄS MER

  7. 20. Mild Wet Torrefaction and Characterization of Woody Biomass from Mozambique for Thermal Applications

    Författare :Carlos Alberto Cuvilas; Weihong Weihong Yang; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Wet torrefaction; Fast Pyrolysis; kinetics; Catalyst;

    Sammanfattning : Mozambique has vast forestry resources and also considerable biomass waste material such as bagasse, rice husks, sawdust, coconut husks and shells, cashew nut shell and lump charcoal waste. The potential of the total residues from the agricultural sector and the forest industry is estimated to be approximately 13 PJ. LÄS MER
