  1. 1. Black liquor gasification : experimental stability studies of smelt components and refractory lining

    Författare :Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; Chemical energy engineering; Kemisk energiteknik;

    Sammanfattning : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). LÄS MER

  2. 2. Effect of chemical and physical properties on combustion of biomass particle

    Författare :Amit Biswas; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering - Chemical process and manufacturing engineering; Kemiteknik - Kemisk process- och produktionsteknik; Energy Engineering; Energiteknik;

    Sammanfattning : Biomass combustion is an interesting alternative to fossil fuel. Modeling and simulation is used for design optimization of biomass boilers and furnace. It is difficult to develop a sufficiently accurate and computationally efficient model because the combustion system is highly complicated multi-scale, multi-phase and multi-physics problem. LÄS MER

  3. 3. Experimental studies of pulverised biomass combustion : Impacts on ash transformations and process temperature

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

    Sammanfattning : Den samlade erfarenhet som finns kring användandet av rena biobränslen för produktion av värme- och kraftvärme kommer till största del från rost- och fluidbäddpannor. Pulvereldningstekniken har traditionellt sett nyttjats mest för kolbränslen, och erfarenheter av rena biobränslen i pulvereldade anläggningar är därför begränsad. LÄS MER

  4. 4. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

    Författare :Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; Experimental investigations; Techno-economic; Wastewater; Flue gas condensate; Waste heat; District heating; Nano-electronics; Cogeneration; Sustainable development; Energiteknik; Energy Technology; Chemical Engineering; Kemiteknik;

    Sammanfattning : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. LÄS MER

  5. 5. Modelling of the pyrolysis of large wood particles

    Författare :Michel Bellais; Krister Sjöström; Björn Zethraeus; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drying; modelling; pyrolysis; shrinkage; wood; Chemical energy engineering; Kemisk energiteknik;

    Sammanfattning : Wood is an interesting alternative to fossil fuels. It is CO2-neutral and widely available. However it is a difficult fuel to handle which features a low energy content. Thus technologies for wood thermal conversion need to be improved. LÄS MER
