The objective of the DOE-HTTT (High-Temperature Turbine Technology) Program is to bring to Technology Readiness, over a six- to ten-year duration, a high-temperature gas turbine for use in a combined-cycle power plant, with coal-derived fuel at a firing temperature of 2600/sup 0/F and with growth capability to 3000/sup 0/F. Phase II, Technology Testing and Test Support Studies, commenced on August 1, 1977, with its objectives to: perform component design and technology testing in critical areas; perform system design and trade-off analyses in sufficient depth to support the component design and test tasks; and update the Phase I combined-cycle plant studies to evaluate the commercial validity of a GE-TRV gas turbine system. During this reporting period the major effort was on motorized rig tests to acquire the heat transfer data needed to design the cooling passages within the rotating components of the TRV gas turbine. A single specimen was tested extensively during the reporting period. The tested specimen, with a 0.083-inch-diameter passage STEM-drilled in an IN718 tube, is prototypical of eight cooling passages in the Stage 1 bucket and all cooling passages in Stages 2 and 3. The performance of this specimen was better than the performances of all smooth specimens tested previously, both in terms of power at boiling transition and in terms of wetted area. These favorable results hve been used to review the cooling flows and the need for turbulence promoters in TRV buckets.
