  1. 1. Alkali Induced Corrosion of 304L, The Influence of Potassium Salts and Water Vapour

    Author : Jesper Pettersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 304L; Alkali; Breakaway Corrosion; KCl; Oxidation; Deposit;

    Abstract : This work investigates the influence of alkali salts on the oxidation of304-type (Fe18Cr10Ni) austenitic stainless steel in laboratory and fieldexposures. Stainless steel coupons were exposed isothermally inlaboratory furnaces at 400-600 °C in 5% O2 and 5% O2 + 40% H2O.Thermobalance exposures were also performed. READ MORE

  2. 2. Alkali Induced High Temperature Corrosion of Stainless Steel - Experiences from Laboratory and Field

    Author : Jesper Pettersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; KCl; 304L; Biomass; Corrosion; Chlorine; Chromate; Waste; Deposit;

    Abstract : The high temperature corrosion of steam superheaters is a major obstacle that has to be overcome in order to increase the electricity generating efficiency of power boilers burning biomass or waste. This thesis addresses this issue by a combination of well-controlled model experiments in the laboratory and short and long term field exposures using cooled probes in full-scale biomass and waste fired boilers.

  3. 3. High Temperature Corrosion of Stainless Steels - The Effects of Chloride Salts and SO2(g)

    Author : Sofia Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : AbstractThe high corrosion rate of superheaters in waste- and biomass- fired plants is often linked to the presence of alkali chlorides. One way to mitigate the corrosion is to replace the superheater material with more corrosion- resistant materials. Another way is to change the corrosive environment by introducing fuel additives.
