1. On the establishment of effective condition-based maintenance for oil-filled electrical transformers to reduce failures due to copper corrosion problems and its role toward sustainable energy
Abstract : Oil-filled electrical transformers are critical equipment for modern societies where a sustainable energy supply is required. Recently, many severe fire and explosion accidents of transformers have been reported due to copper corrosion problems in the form of copper sulfide deposits on the windings. READ MORE

2. The Corrosive Effect of Chlorine Containing Species on Waterwalls and Superheater Materials in Waste and Biomass-Fired Power Plants
Abstract : To increase power generation from waste- and biomass-fired boilers, it is necessary to increase the temperature and pressure of the steam generated. This implies an increase in the temperature both of the waterwalls and of the steam superheaters in the boiler. READ MORE

3. On the estrablishment of effective condition monitoring parameters for copper corrosion problems in mineral oil-filled electrical transformers
Abstract : The power transformer is a critical equipment in which the protection process is essential for modern societies where continuous electric power supplies are required. Copper corrosion problems due to the formation of sulfur deposits on the copper windings of mineral oil-filled power transformers are considered a major issue that can lead to sudden failures, and in some cases, to costly fire and explosion accidents in the power plants.

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. Chemical Interactions between Potassium, Nitrogen, Sulfur and Carbon Monoxide in Suspension-Fired Systems
Abstract : Drastic cuts in global CO2 emissions are needed to mitigate global warming and limit the average temperature increase to well below 2ºC. The power generation sector is largely based on fossil fuels and generates a significant share of the global CO2 emissions. READ MORE
