ABSTRACT:
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).
