  2. 1. Beyond Breakaway Corrosion: Secondary Corrosion Protection of Iron-based Alloys

    Author : Amanda Persdotter; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Breakaway oxidation; High temperature corrosion; Fe-based alloys;

    Abstract : Metallic materials intended for high temperature applications must resist both mechanical and environmental degradation. The ability to withstand corrosion is an important aspect of high temperature materials and is of major concern in, for example, heat and power production. READ MORE

  4. 2. Beyond Breakaway Corrosion: Investigating the Secondary corrosion protection of Iron-based alloys

    Author : Amanda Persdotter; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; Breakaway oxidation; Fe-based alloys; Iron oxide; Secondary corrosion protection;

    Abstract : High temperature corrosion of metallic materials remains a major challenge for many in-dustrial applications. The challenges of high temperature corrosion are often addressed by using highly alloyed materials such as stainless steels or FeCrAl alloys. READ MORE

  5. 3. High temperature corrosion of low-alloyed and stainless steels: mechanistic study of chlorine-induced corrosion

    Author : Mercedes Andrea Olivas Ogaz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steels; low-alloyed steels; pre-oxidation; High temperature corrosion; chlorine-induced corrosion;

    Abstract : The global demand on power generation is constantly increasing and so far, also its environmental impact. The environmental impact could primarily be directed to the power generation being based on fossil fuels, giving a net increase of CO2 to the atmosphere when combusted. READ MORE

  6. 4. High Temperature Corrosion of FeCrAl Alloys in Biomass- and Waste-fired Boilers - The Influence of Alloying Elements in Prediction and Mitigation of Corrosion in Harsh Environments

    Author : Johan Eklund; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Overlay Welding; Waste; High Temperature Corrosion; Silicon; FeCrAl alloys; Breakaway Oxidation; Biomass; HVAF; Coatings;

    Abstract : Combustion of biomass and waste for heat and power production is an alternative to fossil fuels and can be an important step towards a more sustainable future. The electrical efficiency of the fuel-to-energy conversion process is largely dependent on the steam parameters (temperature and pressure) of the combined heat and power (CHP) plants. READ MORE

  7. 5. Materials and Coatings for Superheater Tubes in Biomass- and Waste-fired Boilers

    Author : Vicent Ssenteza; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Secondary Protection; Waste; Boiler; High-Temperature Corrosion; Phase transformation; Biomass; Breakaway Oxidation;

    Abstract : Combustion of biomass and waste fuels has strong potential as an alternative renewable energy source for meeting the increasing global energy demand, while reducing the net release of CO2 into the atmosphere. The combustion of biomass and waste releases flue gases that contain high amount of alkali salts and water vapour, which drive the corrosion of metallic boiler components. READ MORE
