1. Chlorine Induced Corrosion in Biomass and Waste Fired Boilers: Laboratory and Field Investigations
Sammanfattning : The fireside corrosion in biomass and waste fired boilers is widely believed to arise from the presence of chlorine-containing compounds in the fuels. Although many researchers have studied the influence of such compounds on the high temperature corrosion of various steels, the mechanisms underlying chlorine-induced corrosion are still poorly understood.

2. Deposit Induced Corrosion in Biofuel Combustion
Sammanfattning : Deposit induced corrosion is one of the main mechanisms for attack on heat exchangers in biofuel boilers. This severe corrosion decreases the obtainable steam temperature in boilers, thereby the efficiency in production of electricity is reduced. Deposit formation from the gas on superheater tubes are is generally referred to as fouling. LÄS MER
3. Modelling phase separation in Fe-Cr alloys : A continuum approach
Sammanfattning : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. LÄS MER

5. High-Temperature Durability Prediction of Ferritic-Martensitic Steel
Sammanfattning : Materials used for high-temperature steam turbine sections are generally subjected to harsh environments with temperatures up to 625 °C. The superior creep resistance of 9–12 % Cr ferritic-martensitic steels makes them desirable for those critical steam turbine components. LÄS MER
