Oxy T-Fired Boiler Development Project

• This project provides a comprehensive evaluation

Summary

of key oxy process and boiler design parameters under large scale pilot testing

• Oxy tangential firing system will be developed and optimized.

• Key technical data is being obtained defining oxy firing impacts on boiler performance and operation

• Engineering and CFD modeling tools will be refined and validated with test results

• Project results will provide design guidelines and performance data that, along with results of other Alstom oxy projects, provide a strong foundation for the next step of demonstration of an oxy tangentially fired boiler (~250 MWe)
