  2. 1. Corrosion of Stainless Steel in Diesel Exhaust Gas After-treatment Systems with Urea Injection

    Author : Johanna Nockert; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urea; stainless steel; thermal cycling; High temperature corrosion; AES; XPS; condensate; SCR; diesel exhaust;

    Abstract : The demands on lowering the emissions from fossil fuel keep increasing. Together with higher demands of longer component lifetime and lighter vehicles for lower fuel consumption this has led to an increasing use of stainless steels in exhaust after-treatment systems. READ MORE

  4. 2. Developing Humidified Gas Turbine Cycles

    Author : Michael Bartlett; KTH; []
    Keywords : advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Abstract : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. READ MORE

  5. 3. On the Design of Residential Condensing Gas Boilers

    Author : Mikael Näslund; Energihushållning; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; flue systems; modelling; efficiency; condensing boilers; space heating; natural gas; Energiforskning;

    Abstract : Two main topics are dealt with in this thesis. Firstly, the performance of condensing boilers with finned tube heat exchangers and premix burners is evaluated. Secondly, ways of avoiding condensate formation in the flue system are evaluated. READ MORE

  6. 4. Advanced Gas Turbine Cycles with Water-Air Mixtures as Working Fluid

    Author : Niklas Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas turbine cycles; HAT cycles; evaporative cycles; power generation;

    Abstract : Since the early 80's, the worldwide utilization of gas turbines for thermal power generation has increased rapidly. They have less pollution than any other major combustion energy converters. READ MORE

  7. 5. Catalytic tar cleaning of biomass-derived gas with simultaneous catalyst regeneration

    Author : Fredrik Lind; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Tar cleaning; Catalytic gas cleaning; Biomass gasification;

    Abstract : Tar cleaning of raw gas from biomass gasification is a necessary operation before the gas can be used as feedstock for synthetic fuels. The technology for gas cleaning that is commercially available today (scrubber systems), is associated with problems like heat penalties and loss of the chemically stored energy within the tars.
