High Temperature Turbine Technology Program: Phase II. Technology test and support studies. Technical progress report, July 1-September 30, 1981

Technical Report ·
OSTI ID:5279923
The status of work performed on the High Temperature Turbine Technology Program, Phase II Technology Test and Support Studies during the third quarter of 1981, July 1-September 30, 1981 is reported. Testing of the Turbine Spool Technology Rig (TSTR) was initiated. Performance calibrations were performed at several turbine stator throat area settings, followed by steady-state operation at 2600/sup 0/F turbine inlet temperature with fly ash particulates injected into the hot gas stream at the primary zone of the combustor. After approximately 36-1/2 hours of test time, a labyrinth seal on the turbine vane cooling air impeller failed, causing foreign object damage to a number of turbine blades. The test has been interrupted to repair blades, to make changes ot the impeller seal arrangement to preclude future failures and to ensure adequate sealing at the failure location. Observations of the turbine indicate minimal effects from the high temperature and gas stream contaminants. The development status of both the low Btu gas fuel cooled combustor and high temperature, low emissions coal-derived liquid-fueled combustor are reviewed. Both of these programs are in the component fabrication phase leading to test evaluation during the fourth quarter. Control systems status and descriptions for the above items are given. The anaytical studies to support the TSTR and combustor programs are described. Extended time oxidation testing of Nichrome V-Cb material porous mesh for transpiration air cooled turbine airfoils is continuing; furnace exposure time is now over 3000 h.
