Near term application of water cooling to stage 1 nozzles on present day gas turbines results in significant improvements in fuel flexibility and performance. Design and performance calculations for application of a water-cooled stage 1 nozzle are compared to an air-cooled stage 1 nozzle in a heavy duty gas turbine. The results of ash deposition tests of both air-cooled and water-cooled nozzles using simulated residual fuel are presented for firing temperatures of 1850°F and 2050°F. This work was jointly sponsored by the Electric Power Research Institute and General Electric under the Advanced Cooling, Full-Scale Engine Demonstration Program.
