  1. 1. Co-combustion of biomass and waste fuels in a fluidised bed boiler : fuel synergism

    Författare :Anna-Lena Elled; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; co-combustion; biomass; municipal sewage sludge; fluidised bed; combustion; Energi och material;

    Sammanfattning : The objective of this work was to study co-combustion of biomass and waste fuels in a circulating fluidised bed boiler and to detect synergy effects with respect to flue gas composition and ash formation during boiler operation. It was also the aim to perform supplementary thermodynamic equilibrium calculations in order to support the experimental results. LÄS MER

  3. 3. Characterisation of Fuels and Fly Ashes from Co-Combustion of Biofuels and Waste Fuels in a Fluidised Bed Boiler. A Phosphorus and Alkali Perspective

    Författare :Anita Pettersson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; phosphorus recovery; co-combustion; fluidised bed combustion; olivine; Biofuels; zeolites; fertiliser; extraction; refuse derived fuels; kaolin; alkali; sulphur; ash; municipal sewage sludge; biofuels; Energi och material;

    Sammanfattning : In the efforts to create sustainable production of heat and power and to reduce the net CO2 emissions to the atmosphere, alternative fuels are today being utilised. These fuels are, for example, biofuels and waste derived fuels such as different residues from the agricultural sector and the pulp and paper industry, municipal sewage sludge and municipal sorted solid waste.

  4. 4. Co-Combustion of Municipal Solid Waste and Animal Waste : Experiment and Simulation Studies

    Författare :Farzad Moradian; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resursåtervinning; Resource Recovery; Resursåtervinning;

    Sammanfattning : Co-combustion of animal carcasses and slaughterhouse waste products (animal waste), which are classed as high-risk infectious waste, has been considered as a “fuel opportunity” for waste-to-energy boilers. In this study, the impact of co-combustion of animal waste with municipal solid waste (MSW) on operational issues such as bed agglomeration, deposit formation and emission was investigated, employing experimental and theoretical methods.

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

    Författare :Elin Edvardsson; Chalmers University of Technology; []
    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
