Project Description

The goal of this project is to develop materials surfaces that have a combination of good adherence, high resistance to fireside corrosion (especially sulfidation), a minimum effect on material thermal conductivity, and that are tailored for easy application to the waterwall tubes of coal fired boilers to provide effective protection from corrosion and thermal fatigue.

Project Benefits

This project will identify coating materials and application techniques that have the potential to cost-effectively protect coal-fired boiler waterwall tubes in harsh, and corrosive operating environments. Improvement to high-temperature advanced materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, with improved efficiency and operational flexibility, resulting in lower capital and operating costs.
