    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

    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.

  5. 3. Decreased furnace wall corrosion in fluidised bed boilers - The influence of fuel lead content and sewage sludge additive

    Author : Annika Talus; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demolition-wood; alkali chlorides; Furnace wall corrosion; lead oxide; used-wood; salt melt; lead oxychloride; sewage sludge; chlorine-induced corrosion;

    Abstract : Usage of used-wood fuel in the power industry has resulted in increased corrosion problems for metallic materials in the boilers, most probably due to relatively high amounts of chlorine, alkali metals and heavy metals present in the fuel.In this investigation, laboratory exposures were performed in order to study the influence of lead content in a wood-based fuel on the corrosion of selected materials.
