  1. 1. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion

    Author : Daniel Fleig; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SO3; acid dew-point; coal combustion; oxy-fuel; sulfur; flue gas recycle; corrosion; Carbon capture and storage; H2SO4; SO2;

    Abstract : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. READ MORE

  2. 2. The Fate of Sulfur during Oxy-Fuel Combustion

    Author : Daniel Fleig; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulverized coal combustion; oxy-coal; SO3; Oxy-fuel; SO2; sulfur;

    Abstract : Oxy-fuel combustion, where air is replaced by O2 and recycled flue-gas to enrich combustion products, is one of the main CO2 capture technologies suitable for large-scale coal-fired power plants. The changed combustion conditions in oxy-fuel combustion influences the sulfur chemistry, which has recently been the subject of increased attention due to the importance of sulfur species in corrosion and flue-gas cleaning issues.

  3. 3. Surface Reactivity and Electronic Structure of Metal Oxides

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Anneli Önsten; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxides; surfaces; defects; cuprous oxide; zinc oxide; magnetite; water; OH; sulfur dioxide; photoelectron spectroscopy; scanning tunneling microscopy; TECHNOLOGY Engineering physics Material physics with surface physics; TEKNIKVETENSKAP Teknisk fysik Materialfysik med ytfysik;

    Abstract : The foci of this thesis are the metal oxides Cu2O, ZnO and Fe3O4 and their interaction with water and sulfur dioxide (SO2). The intention is to study SO2-induced atmospheric corrosion on a molecular level. All studies are based on photoelectron spectroscopy (PES) and scanning tunneling microscopy (STM) measurements.

  4. 4. Transition metal oxide surfaces Surface structures and molecular interaction

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Markus Soldemo; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Metal oxides are both corrosion products and useful materials with a wide range of applications. Two of the most used metals today are iron and copper. In this thesis, surface structures and molecular interaction with surfaces of iron oxides and copper oxides are studied using spectroscopy and microscopy methods. READ MORE

  5. 5. Strategies to reduce gaseous KCl and chlorine in deposits during combustion of biomass in fluidised bed boilers

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Håkan Kassman; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peat; KCl; Ammonium sulphate; IACM; Combustion of biomass; Sulphation; Chlorine in deposits;

    Abstract : Combustion of a biomass with an enhanced content of alkali and chlorine (Cl) can result in operational problems including deposit formation and superheater corrosion. The strategies applied to reduce such problems include co-combustion and the use of additives. READ MORE
