In 1992, the U.S. Department of Energy forged partnerships with industry and academia under the Advanced Turbine Systems (ATS) Program to go be-yond evolutionary performance gains in utility-scale gas turbine develop-ment. Agreed upon goals of 60 percent efficiency and single digit NOx emissions (in parts per million) represented major challenges in the fields of engineering, materials science, and thermodynamics—the equivalent of break-ing the 4-minute mile. Today, the goals have not only been met, but a knowledge base has been amassed that enables even further performance enhancement. The success firmly establishes the United States as the world leader in gas turbine tech-nology and provides the underlying science to maintain that position. ATS technology cost and performance characteristics make it the least-cost electric power generation and co-generation option available, providing a timely response to the growing dependence on natural gas driven by both global and regional energy and environmental demands. Through the Advanced Turbine Systems (ATS) Program, lofty vi-sions in the early 1990s are now emerging as today’s realities in the form of hardware entering the mar-ketplace. An investment by govern-ment and industry in partnerships encompassing universities and na-tional laboratories is paying signifi-cant dividends. This document examines some of the payoffs emerging in the utility sector result-ing from work sponsored by the U.S. Department of Energy (DOE). Both industrial and utility-scale turbines are addressed under the ATS Program. The DOE Office of Fossil Energy is responsible for the utility-scale portion and the DOE Office of Energy Efficiency and Re-newable Energy is responsible for the industrial turbine portion. The focus here is on utility-scale work implemented under the auspices of the National Energy Technology ATS Program Strategy Laboratory (NETL) for the DOE Office of Fossil Energy. In 1992, DOE initiated the ATS Program to push gas turbine perfor-mance beyond evolutionary gains. For utility-scale turbines, the objec-tives were to achieve: (1) an effi-ciency of 60 percent on a lower heating value (LHV) basis in com-bined-cycle mode; (2) NOx emis-sions less than 10 ppm by volume (dry basis) at 15 percent oxygen, without external controls; (3) a 10 percent lower cost of electricity; and (4) state-of-the-art reliability, avail-ability, and maintainability (RAM) levels. To achieve these leapfrog performance gains, DOE mobilized the resources of leaders in the gas turbine industry, academia, and the national laboratories through unique partnerships. The ATS Program adopted a two-pronged approach. Major systems Introduction
development, under cost-shared co-operative agreements between DOE and turbine manufacturers, was con-ducted in parallel with fundamental (technology base) research carried out by a university-industry consor-tium and national laboratories. Major systems development began with turbine manufacturers conducting systems studies in Phase I followed by concept development in Phase II. Today, one major system development is in Phase III, tech-nology readiness testing, and an-other has moved into full-scale testing/performance validation. Throughout, the university-industry consortium and national laborato-ries have conducted research to ad-dress critical needs identified by industry in their pursuit of systems development and eventual global deployment. www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：Advanced Turbine Systems 先进的涡轮系统
