Combating high temperature corrosion by new materials and testing procedures - Corrosion exposures in the waste fired CFB boiler P15 at Händelö
Research Project , 2014 – 2018

Compared to traditional waste fired CFB boilers, a newly built CFB boiler by FW is designed with a horizontal pass. With this design, a decreased corrosion rate of the super-heater tubes is expected. However, no corrosion tests have been performed, showing if the horizontal pass design displays improved corrosion resistance. We will investigate the corrosion attack of superheaters in the horizontal pass by testing a new class of materials (so called FeCrAl-alloys) as well as state-of-art stainless steels and conventional materials. In order to generate generic knowledge about the corrosion attack the flue gas chemistry, deposit chemistry and corrosion attack be closely monitored and coupled together. This is done by a novel alkali online system, comprehensive deposit analyses, advanced corrosion analysis and complementary equilibrium calculations. The goal is to increase the understanding how the corrosiveness of flue gas varies with temperature. A methodology development .
