The U.S. Department of Energy (DOE) is sponsoring a program to conduct design and development, leading to full scale demonstration of advanced gas turbine systems. The Advanced Turbine Systems (ATS) program is jointly administered by the DOE Office of Fossil Energy (DOE/FE) and the Office of Energy Efficiency and Renewable Energy (DOE/EE). The program will demonstrate commercial prototypes of both utility- and industrial-scale ATS by the year 2000.
The ATS program objectives are: system efficiency 60 percent (lower heating value [LHV]) or greater for utility-scale systems, and an equivalent 15 percent improvement for industrial systems; environmental superiority without the use of post combustion emissions controls; busbar energy costs 10 percent lower than current systems; adaptability to coal or biomass firing; and reliability, availability and maintainability equivalent to current advanced turbine systems.
A competitive procurement process is being used for the selection of contractors to develop and demonstrate full scale systems. System studies were completed by six U.S. turbine manufacturers, and awards were announced in August 1993 for “concept development.” This paper describes one implementation approach to achieve the DOE/ATS targets.
