Abradable Sealing Materials for Emerging IGCC-Based Turbine System
Performer: University of California, Irvine
Project No: FE0011929
Program Background and Project Benefits
This project will provide an improved mechanistic understanding of factors governing the performance of high-temperature abradable seals and degradation mechanisms unique to coal-derived syngas and high-hydrogen content (HHC)-based combustion environments. This improved knowledge will result in better seal design, reduced leakage, and reduced operating costs through increased performance and efficiency. Specifically, this project will investigate several classes of abradable coatings (including metal and ceramic-based systems currently being utilized) under simulated exposures to syngas-based combustion environments to determine their relevant wear/abrasive recession behavior, hardness, stability under cyclic oxidation, and general thermo-mechanical behavior.
