1. 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

2. 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.

3. 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

4. Alloys in Contact with Molten Salts for Thermal Storage Applications
Abstract : The combination of a concentrated solar power (CSP) plant and a thermal energy storage (TES) system is a promising technology for power generation, in that it overcomes the challenges commonly faced by renewable energy systems, such as intermittency, dispatchability, and the gap between the energy supply and energy demand. The third generation (Gen3) CSP plants are designed to increase plant efficiency by using supercritical carbon dioxide (sCO2) instead of steam for the Brayton cycle gas turbines, requiring a minimum operating temperature of 750°C for the TES materials.

5. 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
