  1. 21. Diffusion tests for assessing leaching from incineration residues

    Författare :Jelena Todorovic; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : Increasing amounts of incineration residues need to be disposed, reused or treated, which calls for reliable characterisation methods. Leaching tests are often used for an assessment of release of pollutants from wastes under a variety of leaching factors. LÄS MER

  3. 22. Controlling the mobility of organic carbon (OC) ant its impact on metal transport from incineration residues

    Författare :Malin Svensson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Sammanfattning : Incineration residues contain both inorganic and organic material. The organic material may affect the mobility of pollutants in e.g. landfills or geotechnical constructions. LÄS MER

  4. 23. Investigation of Solids Distribution and External Solids Flux in a Circulating Fluidized Bed Boiler

    Författare :Elin Edvardsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; external solids flux; recirculation rate; solids distribution; CFB boiler; co-combustion;

    Sammanfattning : This work concentrates on two issues regarding combustion in circulating fluidized bed (CFB) boilers. Firstly, the impact of co-combustion of coal with sewage sludge on ash flows, bed material and gas concentrations in a CFB boiler is studied. LÄS MER

  5. 24. Characterisation of organic substances in waste materials under alkaline conditions

    Författare :Ivars Pavasars; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Organic substances are important constituents of different types of inorganic waste in that they can strongly influence the chemical behaviour and environmental properties of the waste materials. Two alkaline waste-material systems containing organic constituents were investigated: a cementitious radioactive waste repository and residues of incinerated municipal solid waste. LÄS MER

  7. 25. Characterisation of residues : Release of contaminants from slags and ashes

    Författare :Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. LÄS MER
