A startup cooling steam generator (36) is disclosed. The generator provides cooling steam (40) to a combustion turbine (2) shortly after the combustion turbine begins to operate. Cooling steam is generated in a once-through system by passing hot exhaust gases generated by the combustion turbine over an immediately adjacent metal tubing apparatus filled with liquid. The startup steam generator (35) is operable in parallel with the main heat recovery steam generator (6).

[ I claim:] [1.] A system for generating steam from a heated exhaust of a combustion turbine comprising: a first steam generation circuit means and a second steam generation circuit means operable in parallel with the first steam generation circuit means for cooling heat sensitive components of the combustion turbine through a cooling circuit within the combustion turbine, said second steam generation circuit means comprising:first means for supplying fluid during startup of the combustion turbine;second means for receiving the fluid and exposing the fluid received from said first means to the heated exhaust generated by the combustion turbine during startup so as to evaporate the fluid and generate steam, said second means being sized to generate a sufficient volume of steam within a substantially minimal time period at startup of the combustion turbine to satisfy the requirements of the cooling circuit; and,third means for providing substantially all of the steam generated by said second means to the combustion turbine cooling circuit so as to cool the combustion turbine during startup.
