  2. 11. On Premixed Gas Fuelled Stirling Engine Combustors with Combustion Gas Recirculation

    Author : Magnus Pålsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; Maskinteknik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; framdrivningssystem; hydraulik; Mechanical engineering; hydraulics; vacuum technology; termodynamik; Termisk teknik; applied thermodynamics; Thermal engineering; heat pipe; ejector; solar energy; CGR; recirculation; EGR; catalytic combustion; premix combustion; Stirling engine; combustor;

    Abstract : The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. READ MORE

  4. 12. Catalytic Incineration of CO and VOC Emissions over Supported Metal Oxide Catalysts

    Author : Per-Olof Larsson; Tillämpad biokemi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titania; Ceria; Manganese oxide; Copper oxide; VOC; CO; Ethanol; Ethyl acetate; Metal oxide catalysts; Catalytic combustion; Catalytic incineration; Alumina.; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Fysicumarkivet A:1999:Larsson;

    Abstract : Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. READ MORE

  7. 15. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia

    Author : Göran Olofsson; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Energy research; Reaction mechanism; Ammonia degradation; Pt CuO Al2O3 Catalysts; SCO; Selective Catalytic Oxidation; Catalytic hot gas cleaning; Bed agglomeration; NOx emissions; Fluidised bed; Biomass combustion; Biogas; Energiforskning;

    Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE
