1. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt
Abstract : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. READ MORE

2. High Temperature Corrosion of Superheaters in Biomass - and Waste-Fired Boilers: Combat on two fronts
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : Carbon dioxide is a greenhouse gas contributing to the greenhouse effect and a significant contribution 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

3. High Temperature Oxidation and Chlorination of FeCrAl alloys
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : AbstractThe constant strive for improved efficiency and lower-cost industrial processes often results in progressively higher temperatures and more aggressive environments. High- temperature corrosion is a well-known problem in biomass- and waste-fired boilers and is one of the obstacles to overcome in achieving a more sustainable society. READ MORE

4. Alkali Induced High Temperature Corrosion of Stainless Steel - Experiences from Laboratory and Field
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : The high temperature corrosion of steam superheaters is a major obstacle that has to be overcome in order to increase the electricity generating efficiency of power boilers burning biomass or waste. This thesis addresses this issue by a combination of well-controlled model experiments in the laboratory and short and long term field exposures using cooled probes in full-scale biomass and waste fired boilers.

5. Fundamental studies on the high temperature corrosion mechanisms of a 22Cr austenitic stainless steel in environments related to oxy-fuel combustion
University dissertation from ; Chalmers tekniska högskola; GothenburgAbstract : This thesis concern the high temperature corrosion mechanisms of stainless steels, with focus on a 22 wt.% Cr FeNiCr alloy (Sanicro 25), in environments related to oxy-fuel combustion, which is a promising technology that can provide enhanced CO2 recovery and sequestration from power plants by using post-combustion capture.
