Integration of High Performance Power Systems (HIPPS) Into Vision 21

Abstract: The U.S. Department of Energy/Federal Energy Technology Center (DOE/FETC)-sponsored High Performance Power Systems (HIPPS) program headed by United Technologies Research Center has identified coal-based combined-cycle power systems using advanced technology gas turbines that could operate at efficiencies approaching 55% (HHV). The HIPPS uses a High Temperature Advanced Furnace (HITAF) to preheat combustion turbine air. The HITAF’s metallic air heaters include a radiator section located in the furnace slagging … Show more

“…The Brayton (gas turbine) cycle, which makes one-half of the electricity in the IFCC, is inherently more efficient than a Rankine (steam) cycle, because there is no loss of the heat of vaporization of the water to make steam in the Brayton cycle. Therefore, an IFCC system has the potential to be more efficient than a system based solely on the Rankine cycle (Robson et al, 2002).…”

“…The EERC has previously demonstrated a very high-temperature heat exchanger (HTHX) that could be used to produce pressurized air at up to 1090°C for an indirectly fired combined-cycle (IFCC) power plant. An IFCC using this type of heat exchanger has the potential to reach efficiencies of 45% when firing coal and over 50% when a natural gas-fired duct burner is used to additionally heat the gas entering the turbine, efficiencies similar to those of an integrated gasification combined cycle, but with operation almost identical to those of current pulverized coal (pc)-fired boilers [5,6].…”
