Presently the highest steam temperature allowed at the turbine inlet is about 620°C.
GE Gas Turbine Performance Characteristics
ncad.netAs shown in Figure 5, the firing temperature on a turbine with steam-cooled nozzles (GE’s cur-rent “H” design) has an increase of 200 degrees without increasing the combustion exit temperature. An alternate method of determining firing tem-perature is defined in ISO document 2314, “Gas Turbines – Acceptance Tests.” The firing tem-
