  1. 26. Experimental and modelling studies of radiative heat transfer in flames

    Författare :Daniel Bäckström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence-Radiation Interaction; Particle radiation; Radiative heat transfer;

    Sammanfattning : Combustion of solid fuels is used extensively for electricity generation purposes. However, combustion of fossil fuels leads to CO2 emissions which enhance the greenhouse gas effect. Carbon capture and storage (CCS) is a proposed solution where the CO2 is captured and stored instead of being emitted to the atmosphere. LÄS MER

  3. 27. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

    Författare :Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.

  4. 28. Black Liquor Gasification-Based Biorefineries – Determining Factors for Economic Performance and CO2 Emission Balances

    Författare :Karin Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefineries; system expansion; second generation biofuels; black liquor gasification; kraft pulp and paper mill; global CO2 emissions; heat integration; energy market scenarios;

    Sammanfattning : Biorefineries constitute an attractive future development option for the pulp and paper industry, allowing mills to produce not only pulp or paper but also other value-added products. Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery in kraft pulp and paper mills. LÄS MER

  5. 29. Externally fired gas turbine cycle based on biomass gasification gas as fuel

    Författare :Fabiola Baina Veizaga; Torsten Fransson; Lasse Rosendhal; KTH; []
    Nyckelord :Externally fired micro gas turbine; heat transfer; combustion of biomass derived gas; micro combined heat and power; Energiteknik; Energy Technology;

    Sammanfattning : Energy services are essential for the development of societies, reduce poverty, and improve the living standards of inhabitants. The conventional routes to provide energy services employ fossil fuels. However, this involves environmental and availability concerns. LÄS MER

  7. 30. Fluidized bed plants for heat and power production in future energy systems

    Författare :Guillermo Martinez Castilla; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass combustion; combined heat and power; thermal power plant; process control; operational flexibility;

    Sammanfattning : Fluidized bed (FB) plants are used for heat and power production in several energy systems around the world, with particular importance in systems using large shares of renewable solid fuel, e.g., biomass. LÄS MER
