Project Description

The goal of this project is to address critical corrosion and environmental effects issues in coal-fired boilers ranging from boiler water walls to super heater tubes. Specific technical objectives are to obtain better understanding of (1) hydrogen induced cracking in boiler water walls and which alloys may be more resistant to this type of degradation and (2) the effect of shot peening on steam side oxidation of austenitic super heater tubes. Such understanding is critical to developing more accurate lifetime prediction models for current alloys used in boilers, and advanced alloys and surface modifications that are being considered for use in advanced coal-fired power systems.

Project Benefits

Addressing critical corrosion and environmental effects issues in coal-fired boilers ranging from boiler water walls to super heater tubes is expected to improve performance of commercial and model alloys in controlled laboratory experiments to simulate advanced fossil boiler conditions.
