Superheaters - an overview | ScienceDirect Topics

In Fig. 8.10 [49], the corrosion of superheater tubes in a stoker boiler OR50 is shown. The outlet temperature of steam was 485°C. The boiler burned coal with a chlorine content of Cl ar = 0.3% mainly as NaCl from salty mine water and sulfur S ar = 0.4%, which corresponded to S/Cl = 1.33. After 3000 hours of operation, there was a failure.
