  1. 1. Förbränning av termokemiskt behandlade biobränslen : en studie av biomassa som genomgått en pyrolys-, torrefierings- eller steam explosionprocess

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Karl Lindberg; [2014]
    Nyckelord :Pyrolys; Steam explosion; torrefiering; förbränning; syreberikning;

    Sammanfattning : EU har som mål att år 2020 ha minskat utsläppen av växthusgaser med 20 % och ökat andelen förnyelsebar energi till 20 %. I Sverige är andelen fossilt bränsle som förbränns ca 30 %. Denna studie syftar till att utreda om termokemiskt behandlade biobränslen kan ersätta de kommersiella fossila bränslena. LÄS MER

  3. 2. Combustion of sludge in Fortum’s plants with possible phosphorus recycling

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Victor Hoffman; Anton Marmsjö; [2014]
    Nyckelord :Sludge combustion; phosphorus;

    Sammanfattning : The management of waste is by all means a great challenge to any society. In Sweden, the past decades has seen legislation progressing in congruence with concerns over environmental stress from inefficient waste management. The legislative changes aim primarily to promote waste reduction and better waste utilization. LÄS MER

  4. 3. Computational fluid dynamics (CFD) study of co-firing of coal and pretreated biomass

    Master-uppsats, KTH/Energi- och ugnsteknik

    Författare :A S M Abdul Hye; [2014]
    Nyckelord :Computation fluid dynamics; co-firing; emission; boiler; coal; biomass; torrefied biomass;

    Sammanfattning : This master thesis describes the co-firing concept, benefits and opportunities of pretreated biomass in pulverized coal boilers for industrial use. Burning fossil fuels, i.e. coal is under immense political pressure as European Union (EU) and other countries are trying to bring down the CO2 emission. LÄS MER

  5. 4. The state of the Latvian wood pellet industry : a study on production conditions and international competitiveness

    Master-uppsats, SLU/Dept. of Forest Products

    Författare :Anders Gemmel; [2014]
    Nyckelord :bioenergy; export; biomass; renewable energy; pellet mills; the Baltic States; support schemes ;

    Sammanfattning : In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. LÄS MER

  7. 5. Consequences of new sources of supply on wood fuel prices

    Uppsats för yrkesexamina på avancerad nivå, Matematiska institutionen

    Författare :Anders Dahlberg; [2010]
    Nyckelord :;

    Sammanfattning : The use of wood fuels in Western Europeis growing rapidly each year. The co-firing of wood fuel in coal- fired powerplants to reduce CO2 emissions makes thedemand accelerate even more and astrained supply could be a reality in anear future. Regions as Canada andNorth-West Russia have large biomasspotentials and small internal marketsfor wood fuels. LÄS MER
