  1. 41. Alkali-enhanced gasification of biomass : laboratory-scale experimental studies

    Författare :Albert Bach-Oller; Kentaro Umeki; Viktor Scherer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkali; biomass; gasification; tar; soot; potassium; char; syngas; enhanced; Energiteknik; Energy Engineering;

    Sammanfattning : Gasification seeks to break carbonaceous materials into synthetic gas (CO+H2) which can be subsequently upgraded into valuable products. Thus gasification can be utilized to convert low grade biomass stocks into carbon-neutral chemicals heat and power. LÄS MER

  3. 42. Co-gasification of black liquor and pyrolysis oil: Fuel conversion and activity of alkali compounds

    Författare :Albert Bach Oller; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Gasification using entrained flow reactors generates syngas that can be upgraded tochemicals with little gas cleaning. Black liquor (BL) is a by-product from pulping industrythat consists of residual wood constituents and spent pulping chemicals. LÄS MER

  5. 44. Increasing the value of household appliances by adding a heat pump system

    Författare :Peder Bengtsson; Jonas Berghel; Tomas Persson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat pump; Appliances; ASKO; Energy system; Energiteknik; Energy Technology;

    Sammanfattning : Historically, domestic tasks such as preparing food and washing and drying clothes and dishes were done by hand. In a modern home many of these chores are taken care of by machines such as washing machines, dishwashers and tumble dryers. LÄS MER

  7. 45. Experimental analysis of thermal mixing at reactor conditions

    Författare :Mattia Bergagio; Henryk Anglart; Paolo Vinai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing estimator; empirical mode decomposition; Hilbert-Huang transform; uncertainty assessment; radial heat flux; Energy Technology; Energiteknik; Fysik; Physics;

    Sammanfattning : High-cycle thermal fatigue arising from turbulent mixing of non-isothermal flows is a key issue associated with the life management and extension of nuclear power plants. The induced thermal loads and damage are not fully understood yet. LÄS MER
