97/04044 High performance power systems (HIPPS) for the 21st century

Abstract

In Phase I of the DoE/PETC-sponsored Combustion 2000 Program, a team led by United Technologies Research Center identified a 300 MW High Performance Power Systems (HIPPS) which met the DOE goals of 47% efficiency, emissions of 10% NSPS, and costs lower than a PC-fired steam station. This HIPPS was based on a heavy frame gas turbine commercially available in the 1996-97 time frame. As part of the HIPPS Phase II program, advanced aero-derivative gas turbines have been investigated for use in HIPPS that could appear in the latter part of the first decade of the 21st century. These engine configurations are based on the EPRI/Utility Consortium-sponsored Collaborative Advanced Gas Turbine (CAGT) program in which uses technology from the latest 80-100,000 lb thrust aero engines for the large wide-body civil aircraft, but incorporate industrial features that could allow turbine temperatures approaching 3000 F and pressure ratios over 50/1. A variety of engine configurations and power cycles were analyzed for use in the advanced HIPPS. These include simple and intercooled gas turbines used in combined cycle and Humid Air Turbine (HAT) versions of HIPPS. The HIPPS plants were for both {open_quotes}greenfield{close_quotes} and repowering applications. For systems having one gas turbine, power outputsmore » were in the 150 MW to 300 MW range with efficiencies of 45% to 55% (HHV) depending on application and cycle variation.« less
