  1. 11. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

    Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER

  3. 12. Development and Application of Uncertainty Analysis Approaches for MELCOR Simulations of Severe Accidents

    Författare :Wanhong Wang; Weimin Ma; Florian Fichot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Severe accident; MELCOR; uncertainty analysis; Wilks’ method; Bootstrapped artificial neural network; deterministic sampling method; 95 95 tolerance limit.; Svåra haverier; MELCOR; osäkerhetsanalys; Wilks’ metod; artificiella neuronnät; deterministiska urvalsmetoder; 95 95-toleransgränser.;

    Sammanfattning : The contemporary needs in advancing safety analysis methods and the increasing stringency in light water reactor (LWR) safety in the post-Fukushima era require more advanced and systematical approaches for severe accident analyses. The best estimate plus uncertainty (BEPU) methods are among such approaches and have been widely used for deterministic safety analysis (DSA) of design basis accidents (DBAs). LÄS MER

  4. 13. Modelling of Solid Oxide Fuel Cells Applied to the Analysis of Integrated Systems with Gas Turbines

    Författare :Azra Selimovic; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical physics; plasma; plasmas; Gaser; fluiddynamik; Termisk teknik; termodynamik; Gases; fluid dynamics; applied thermodynamics; Thermal engineering; Hybrid Cycles; Gas Turbines; Mathematical Modelling; Electrochemistry; Fuel Cells; Solid Oxide Fuel Cells; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; gravitation; statistisk fysik; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity;

    Sammanfattning : Solid oxide fuel cells (SOFCs), working at high temperatures with an incomplete fuel oxidation process, have become an interesting candidate for combination with conventional power generation technology, such as gas turbines, in order to develop power plants that are both functional and efficient. An absolute condition for successful analysis and optimisation of such plants is the existence of reliable simulation tools. LÄS MER

  5. 14. Statistical energy analysis and variational principles for the prediction of sound transmission in multilayered structures

    Författare :Mathias Barbagallo; Svante Finnveden; Jean-Louis Guyader; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical energy analysis; porous materials; biot theory; variational principles; hamilton principle; double walls; multilayered structures; Järnvägsgruppen - Ljud och vibrationer; Järnvägsgruppen - Ljud och vibrationer;

    Sammanfattning : Multilayered structures have many application in industry and society: they have peculiar properties and serve a variety of purposes, like structural support, thermal insulation, vibrational and acoustic isolation. This thesis concerns the prediction of sound transmission in multilayered structures. LÄS MER

  7. 15. Strengthening the Municipal Energy Planning – Integration into Comprehensive Planning, Performance of Impact Assessment and Inclusion of National Environmental Objectives
