abstract

The EPRI projects for the development of water-cooled gas turbine power plants have been completed, while the DOE project on this subject (HTTT) is completing Phase II with little likelihood for further funding. This paper presents the prospects of water-cooled power plants as currently evaluated at EPRI. It is concluded that: water cooling designs for the stationary components are commercially ready, but technology development work is still required for the rotating components; water cooled turbines can have much lower ash deposition and corrosion rates than air cooled ones when firing on ash-containing fuels; water cooling provides considerable increase in specific power, but there is little advantage, if any, in efficiency compared to air cooling. The water-cooled gas turbine has its main attractiveness for operation with ash-containing fuels at base load. However, since this type of operation is not currently foreseen for American utility practice, the near-term continued development of the water-cooled gas turbine power plant is not expected to proceed.
