High performance power plant systems (HIPPS) -- Coal-based gas turbine power systems for the 21st century
The Department of Energy's Federal Energy Technology Center (FETC) is sponsoring the Combustion 2000 Program aimed at introducing cleaner and more efficient advanced technology coal-based power systems early in the 21st century. As part of this program, the United Technologies Research is leading a team to identify and develop the technology for a High Performance Power System (HIPPS) that will provide in the near term, 47% efficiency (HHV), and meet emission goals only one-tenth of current New Source Performance Standards for coal-fired power plants. In addition, the team has identified advanced technologies that result in HIPPS with efficiencies over 56% (HHV). These HIPPS also can reduce greenhouse gas emissions, mainly CO{sub 2}, by as much as 50% compared to current coal-fired stations. The HIPPS is a combined cycle that uses a coal-fired High Temperature Advanced Furnace (HITAF) to preheat compressor discharge air in both convective and radiant heaters. The heated air is then sent to the gas turbine where additional fuel, either natural gas or distillate, is burned to raise the temperature to the levels of modern gas turbines. Steam is raised in the HITAF and in a Heat Recovery Steam Generator for the steam bottoming cycle. With state-of-the-art frame type gas turbines and commercially available materials in the HITAF, the DOE efficiency goal of 47% is met in a system with at lest two-thirds of the heat input furnished by coal. By using advanced aero-derivative engine technology and HITAF heat exchanger materials which have not yet been made available to the general marketplace, HIPPS configurations have been identified result in efficiencies over 50% (HHV). When these advances are used in Humid Air Turbine (HAT) HIPPS performance approaches 57% (HHV). These higher temperature heat exchangers also would allow efficient repowering on coal-fired plants with current technology gas turbines. The following paper contains descriptions of several advanced HIPPS configurations and discusses the HITAF and the experience with the heat exchanger test units that permit reasonable extrapolation to higher operating conditions.
