1. On the On-line Tools for Treatment of Deterioration in Industrial Processes
Abstract : For industrial processes high availability and efficiency are important goals in plant operation. This thesis presents studies and development of tools for on-line treatment of process deterioration and model and sensor errors in order to achieve these goals. READ MORE

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. Furnace Wall Corrosion in a Wood-fired Boiler
Abstract : The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals.

4. High-Temperature Corrosion in Waste-Fired Boilers: Insights into material selection for fluidized bed heat exchangers and the corrosivity of PbCl2
Abstract : The replacement of fossil fuels with waste-derived fuels for heat and electricity production has gained significant momentum in the European Union (EU), especially in the wake of the implementation of stricter waste management directives and the pursuit of ambitious climate goals. Combustion of waste, however, leads to the formation of a complex and highly corrosive flue gas that cause severe corrosion on important boiler equipment. READ MORE

5. 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
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
