Although materials and coatings are being developed for use in
syngas-fueled turbine engines, no test system is available today to effectively
measure their capabilities under representative engine conditions.
This project
will design a low-cost test rig that can be used to understand how trace
contaminants in a coal-derived synthesis gas
(syngas) fueled combustion environment interact with advanced turbine
blade materials and coatings. The
degradation processes that may be studied with this rig include deposition,
erosion, and corrosion from heavy metals or particulates and gaseous species
such as SOx, alkali compounds, or HCl. The
rig also will allow for the study of thermal and mechanical loads on the test
specimens, emissions measurements, and will simulate actual engine conditions.
In Phase I, a conceptual design and analysis were conducted of the rig
test section to demonstrate that desired test conditions (thermal gradient and
heat flux) could be achieved, and that the proposed rig is viable.
The test chamber was designed to test multiple specimens concurrently
with the specimens loaded statically. An
instrumentation plan was developed to address the need to monitor specimen
temperature and identify whether coating spallation occurs.
In Phase II, an analytical verification of the test section design will
be performed. In addition, the
combustion system that supports the test rig will be designed and built.
Commercial
Applications and Other Benefits as
described by awardee: Higher
performance and lower emission requirements are driving the need for advanced
turbine thermal barrier coatings for industrial gas turbines, land-based
aeroderivative power turbines, and military aero engines.
These applications require accurate representation of turbine engine
pressures, temperatures, and air velocities in order to evaluate candidate
coatings with confidence. The
proposed rig should enable versatile and accurate testing in a very affordable
and efficient manner to support new turbine designs.
