2. 1. High temperature corrosion of low-alloyed and stainless steels: mechanistic study of chlorine-induced corrosion

   Author : Mercedes Andrea Olivas Ogaz; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steels; low-alloyed steels; pre-oxidation; High temperature corrosion; chlorine-induced corrosion;

   Abstract : The global demand on power generation is constantly increasing and so far, also its environmental impact. The environmental impact could primarily be directed to the power generation being based on fossil fuels, giving a net increase of CO2 to the atmosphere when combusted. READ MORE

4. 2. High temperature corrosion during waste incineration : characterisation, causes and prevention of chlorine-induced corrosion

   Author : Peter Viklund; Christofer Leygraf; Jan Froitzheim; Staffan Hertzman; Sweden Stockholm Swerea KIMAB AB; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; high temperature corrosion; waste incineration; superheater tubing; steel; alkali; chlorine; suphur; Chemistry; Kemi;

   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. 3. Superheater corrosion in biomass and waste fired boilers : Characterisation, causes and prevention of chlorine-induced corrosion

   Author : Peter Viklund; Christofer Leygraf; John Nicholls; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature corrosion; waste; biomass; superheater tubes; steel; alkali; chlorine; sulphur;

   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.

6. 4. Investigations of Chlorine-Induced High Temperature Corrosion of Steels

   Author : Nicklas Folkeson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; sulphur; alkali; chlorine; field exposures; HCl-induced corrosion; high temperature corrosion; deposits.; chloride-induced corrosion; waste; 310S; HCl;

   Abstract : The high corrosivity of the fireside environment in waste and biomass fired boilers is commonly attributed to the presence of chlorine-containing compounds. Chlorine-induced high temperature corrosion is not well understood, however. READ MORE

7. 5. 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.
