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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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.

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

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

   Sammanfattning : 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. LÄS MER

5. 4. Pathophysiology and treatment of chlorine gas-induced lung injury : an experimental study in pigs

   Författare :Jianpu Wang; Kai Knudsen; Östergötlands Läns Landsting; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : One of the most threatening scenarios in disaster medicine is the accidental release of toxic gases with the exposure of many people. In this respect, chlorine gas remains a significant threat due to its abundant use and transport through densely populated areas in modem society. LÄS MER

7. 5. Effects of Varying Combustion Conditions on PCDD/F Formation

   Författare :Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

   Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. LÄS MER
