1. Superheater corrosion in biomass and waste fired boilers : Characterisation, causes and prevention of chlorine-induced corrosion
Abstract : Biomass and waste fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work high temperature corrosion of superheater alloys, and methods to mitigate the problem, have been investigated by laboratory studies and controlled field exposures in commercial boilers.

2. Deposit Induced Corrosion in Biofuel Combustion
Abstract : 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. READ MORE

3. Materials and Coatings for Superheater Tubes in Biomass- and Waste-fired Boilers
Abstract : Combustion of biomass and waste fuels has strong potential as an alternative renewable energy source for meeting the increasing global energy demand, while reducing the net release of CO2 into the atmosphere. The combustion of biomass and waste releases flue gases that contain high amount of alkali salts and water vapour, which drive the corrosion of metallic boiler components. READ MORE

4. High temperature corrosion during waste incineration : characterisation, causes and prevention of chlorine-induced corrosion
Abstract : Waste-fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work the high temperature corrosion of candidate superheater alloys have been investigated by detailed laboratory studies and controlled field exposures in full-scale boilers. READ MORE

5. High Temperature Corrosion in Fluidised Bed Environment
Abstract : Successful material selection for power plants is the result of understanding the environment in each boiler. The boiler environment is affected by fuel chemistry, co-firing, process control and deposits as well as boiler type, design, size and load. READ MORE
