Gas turbines of GE make are denoted by Frame i.e. Frame V, Frame - VI, Frame - IX etc. Frame - 9E gas turbine means serial no. 9001 , 9171 E etc For 9171 E - 9 means the frame number, 17 means 170000 HP, 1 means single shaft and E is the latest modification 9FA is a high end frame 9 machine i.e. has higher rating than 9E GE gas turbines were basically divided into 2 different classes. 1. E - class Ex: 6B, 9E 2. F - class Ex: 6FA, 7FA, 7FB, 9FA, 9FB,9FA+e F class machines are newer machines and has higher power generation capacity. 9FA means : "9" indicates Frame size and "F" indicates F class machine. FA and FB are two categories of F - class machines. 9E means : "9" indicates Frame size and "E" indicates E class machine. 9FA+e means : "9" indicates Frame size, "F" indicates F class machine and "+e" indicates extended version of 9FA.

For ex: 9FA+e 'inspection interval' is more compared to 9FA. In Steam Turbine using superheated steam as an inlet steam, What happens if I use air in  place of steam with the same parameters ?
