  1. 21. Combined solar and pellet heating systems : Study of energy use and CO-emissions

    Författare :Frank Fiedler; Rebei bel Fdhila; Wolfgang Streicher; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar heating; pellet heating; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Sammanfattning : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. LÄS MER

    Sammanfattning : This thesis describes various aspects of the development of a multi-disciplinary aero engine conceptual design tool, TERA2020 (Techno-economic, Environmental and Risk Assessment for 2020), based on an explicit algorithm that considers: engine performance, engine aerodynamic and mechanical design, aircraft design and performance, emissions prediction and environmental impact, engine and airframe noise, and production, maintenance and direct operating costs.As part of this research effort, a newly-derived semi-empirical NOx correlation for modern rich-burn single-annular combustors is proposed.

  5. 24. Metal retention from leachate using Industrial Waste Products

    Författare :Emma Nehrenheim; Sylvia Waara; Hanna Obarska-Pemplowiak; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Sammanfattning : Landfill leachate arises when water percolates through a landfill. The degree and type of pollution is dependent on the content of the landfill but also on a range of other factors, including the age of the landfill and the landfilling technique. LÄS MER
