Development of high temperature turbine subsystem technology to a ''technology readiness status'': Phase I. Second quarterly report, October--December 1976
Two gasification systems, the advanced fixed bed and the entrained bed, have been evaluated and compared in order to select a single system for an Overall Plant Design Description (OPDD). Comparisons made to date favor the fixed bed system due to more favorable control characteristics, more experience, and a significantly higher overall plant thermal efficiency. Also selected for inclusion in the OPDD was the Benfield Acid Gas Removal System to be used for gas cleanup. Included herein are the results of parametric studies on the coal-derived liquid combined cycle plant. A Failure Mode and Effects Analysis has begun with Fault Tree preparation based on specific constraints. Design evaluations of various turbine cooling schemes and their influence on the balance-of-plant design plus development requirements are shown. The resulting prime turbine design of all water cooled nozzles and buckets is illustrated plus the backup design of water cooled nozzles and steam cooled buckets. Combustor design efforts are shown on the annular, sectoral, and cylindrical concepts. The mechanical assembly difficulties of the annular design and the flow separation problems of the cylindrical design are overcome by the sectoral design which is derived from annular combustor technology.
