1. Thin-Film Coated Steel Foils as Interconnects for Solid Oxide Fuel Cells (SOFC)
Abstract : Solid Oxide Fuel Cells (SOFCs) are electrochemical energy conversion devices that have the potential to achieve high efficiencies while using a broad range of fuels. The advancement of the technology has however been hindered by a number of technical and economic barriers, one of which is the durability and cost of the bipolar plate or interconnect that connects individual cells in series to form a so-called ‘stack’.

2. High temperature corrosion in a biomass-fired power boiler : Reducing furnace wall corrosion in a waste wood-fired power plant with advanced steam data
Abstract : The use of waste (or recycled) wood as a fuel in heat and power stations is becoming more widespread in Sweden (and Europe), because it is CO2 neutral with a lower cost than forest fuel. However, it is a heterogeneous fuel with a high amount of chlorine, alkali and heavy metals which causes more corrosion than fossil fuels or forest fuel. READ MORE

3. Degradation Mechanisms of Heat Resistant Steel at Elevated Temperatures : In an Iron Ore Pelletizing Industry
Abstract : This thesis focuses on the different degradation mechanisms of the stainless steel in a travelling grate in a Grate-Kiln iron ore pellet indurator. The travelling grate is a conveyor belt that transports green-body pellets to a rotary kiln while the pellets are being dried and pre-heated to a temperature of 900-1100 °C by recycled hot air.

4. High Temperature Corrosion Behavior in Biomass- and Waste-Fired Boilers - Insights into catastrophic corrosion and corrosion mitigation techniques
Abstract : Carbon dioxide is contributing to the greenhouse effect and a significant part comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. READ MORE

5. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels
Abstract : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. READ MORE
