    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

    Sammanfattning : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

  4. 3. On Gas Turbine Diagnostics with Emphasis on Combustion Chambers

    Författare :Raik Orbay; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent combustion; PDA; swirl stabilisation; PIV; off-design.; Gas turbine; experimental methods; LDA; atomisation; emission measurements;

    Sammanfattning : The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. LÄS MER

  5. 4. High temperature aerosol formation and emission minimisation during combustion of wood pellets

    Författare :Henrik Wiinikka; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Combustion of solid biomass under fixed bed conditions is a common technique to generate heat and power in both small and large scale grate furnaces (domestic boilers, stoves, district heating plants). From both an environmental and economical perspective, one of the most interesting alternatives to replace oil and electricity for heating of family houses and apartments in Sweden is wood pellets made of stem wood sawdust from pine and spruce.

  7. 5. SiCFET gassensors : theory, developent, and applications to flue gas cleaning processes  in power plants

    Författare :Zhafira Darmastuti; Anita Lloyd Lloyd Spetz; Lars Ojamäe; Mike Andersson; Niclas Lindqvist; Mikael Larsson; Jaco Visser; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Environmental and health concerns lead to stricter regulations on power plant emission. Sensors play an important role, not only as part of the process control to ensure that the effluent stays under the regulated values, but also to increase the pollution removal efficiency and to decrease the reagent consumption.
