  1. 1. Chemical Properties of FBC Ashes

    University dissertation from Chalmers University of Technology

    Author : Britt-Marie Steenari; Chalmers tekniska högskola.; Chalmers University of Technology.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; Environmental engineering; ash chemistry; ash hydration reactions; ash leaching; ash melting; CaS; deposits; environmental impact of ash handling; FBC; PFBC; forest fertiliser; fouling; fuel additives; plant nutrient recycling; sintering; straw ash; wood ash characteristics; wood ash recycling;

    Abstract : In this thesis several aspects of ash chemistry are discussed. An issue of primary concern for boiler operators is the formation of ash deposits. New biomass fuels are introduced, many of which have unfavourable ash melting behaviour due to high levels of alkali metal species and chlorine. READ MORE

  2. 2. Unsaturated Phase Environmental Processes in MSWI Bottom Ash

    University dissertation from Media-Tryck

    Author : Aamir Ilyas; Lunds universitet.; Lund University.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency Domain; Bottom Ash; Hydrogen Recovery; Leaching; Microbial Respiration; Eco-toxicity; Solid Waste;

    Abstract : Every year, Sweden produces 1.5 million tons of incineration residues from waste to energy plants. Among these residues bottom ash(BA) due to its large volume and good geotechnical quality can be reused as an alternative construction material. READ MORE

  3. 3. Ecotoxicological classification of ash materials

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Author : Sara Stiernström; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ecotoxicity; ash; classification; leaching; Waste Framework Directive; CLP-Regulation; Hazard Identification; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Incineration of waste is increasing in the EU. However, in the incineration process, both fly and bottom ash materials are generated as waste that requires further action. A common goal throughout Europe is to find ways to utilize ash materials in an environmentally and economically efficient manner in accordance with the current legislation. READ MORE

  4. 4. Environmental assessment of municipal solid waste incinerator bottom ash in road constructions

    University dissertation from Stockholm : KTH

    Author : Susanna Olsson; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bottom ash; environmental impact; LCA; waste management; leaching; copper; dissolved organic carbon; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Abstract : There are several incentives for using bottom ash from municipal solid waste incineration (MSWI bottom ash) as a construction material, such as for road construction. These incentives include decreased disposal of material on landfills and a reduced amount of raw material extracted for road building purposes. READ MORE

  5. 5. Distribution and chemical association of trace elements in incinerator residues and mining waste from a leaching perspective

    University dissertation from Örebro : Örebro university

    Author : Naeem Saqib; Örebro universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; trace elements; partitioning; fly ash; bottom ash; speciation; association; risk assessment; wood waste; incineration; mining waste; Chemistry; Kemi;

    Abstract : Incineration is a mainstream strategy for solid waste management in Sweden and all over the world. Improved knowledge and understanding about the distribution of trace elements (in ashes) during incineration, and how trace element partitioning respond to the changes in waste composition, are important in terms of combustion process optimization and plant efficiency.
