Two paths for the high performance power systems (HIPPS)

In the DoE/FETC-sponsored Combustion 2000 Program, a team led by United Technologies Research Center has identified a 300 MW High Performance Power Systems (HIPPS) which meets the DoE goals of 47% efficiency, emissions of 10% NSPS, and costs lower than a PC-fired steam station. This HIPPS, and other versions of advanced HIPPS, used natural gas to boost the air heated in the High Temperature Advanced Furnace (HITAF) to the design levels of the particular gas turbine selected. While there are many advantages to using supplemental gas, there are also advantages to an {open_quotes}all-coal{close_quotes} HIPPS. A variety of engine configurations and power cycles were analyzed for use in an all-coal HIPPS. These include intercooled gas turbines used in combined cycle and Humid Air Turbine (HAT) versions of HIPPS. These HIPPS plants are suitable for both {open_quotes}greenfield{close_quotes} and repowering applications. For systems having one gas turbine, power outputs were in the 150 MW to 300 MW range with efficiencies better than those projected for advanced PC-fired steam plants.
