    Sammanfattning : Mankind has to provide a sustainable alternative to its energy related problems. Bioenergy is considered as one of the potential renewable energy resources and as a result bioenergy market is also expected to grow dramatically in future. However, logistic issues are of serious concern while considering biomass as an alternative to fossil fuel. LÄS MER

  5. 4. Combustion of gasified biomass: : Experimental investigation on laminar flame speed, lean blowoff limit and emission levels

    Författare :Nur Farizan Binti Munajat; Torsten Fransson; Catharina Erlich; Jens Klingmann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass gasification; gasified biomass; laminar flame speed; blowoff; emissions;

    Sammanfattning : Biomass is among the primary alternative energy sources that supplements the fossil fuels to meet today’s energy demand. Gasification is an efficient and environmental friendly technology for converting the energy content in the biomass into a combustible gas mixture, which can be used in various applications. LÄS MER

  7. 5. Modelling of Biomass Combustion in Furnaces

    Författare :Torbern Klason; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; applied thermodynamics; grate fired boiler; Biomass combustion; computational analysis of boiler performance; Thermal engineering;

    Sammanfattning : Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. LÄS MER
