A case history is presented where serious corrosion occurred on the tubes and on the protection shells of the superheaters tubes. A decrease of the load changed the corrosion mode to localized corrosion outside the zone of soot blowing. A provisional equilibrium diagram for the reactions involved illustrates the combined influences of temperature, of the oxidizing character of the environment and of the HCl content on corrosion. The corrosive action of burning particles and the need for controlled start‐up conditions are emphasized.
