Answer / mob

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

Answer / naga

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.

Answer / varun kamboj

GT 9FA+e MEANS
9- SIZE OF FRAME.
F- CLASS OF MACHINE.
+e VERSION OF MACHINE

9E GT MEANS - 9171 SERIAL NO. WHICH DENOTES

9-FRAME SIZE
17- 170000 HP
1- MEANS SINGLE SHAFT

Answer / madhu

GE 9FA &9E MEANS FRAME 9A &9E GAS TURBINES, 9= MODEL
NUMBER,A&E VERSIONS

Answer / satyadar

ge ms9001 fa means

ms mechanical shaft
9- frame size
f- class
a- version

actually it orginal coding was pg 9351 fa
pg- power generation
35- 350000 hp
1- single shaft
f- class
a- version

Answer / jayant c dusane

GE9FA and 9E
9FA = 9- frame size
f- class
a- version

9E = 9- frame size

e- class

Answer / ahmed mamdouh

9FA = 9- frame size
F- class
A- version
9E = 9- frame size

E- class

Answer / nithi

GE Frame 9FA Machine
9=FRAME
F= MEANS CLASS LIKE E CLASS MACHINE TURBINE INLET
TEMPERATURE AROUND 1070 DEGC AND F CLASS MACHINE TURBINE
INLET TEMPERATURE IS AROUND 1180 DEG C.
A = MEANS ANUALR COMBUSTION.

Answer / bhola shanker

9E turbines have cranking motor,  no lift oil for turbine bearings,  having additional bearing near the marriage coupling I.e.,in between compressor sand turbine, because of lower capacity the generator is air cooled, 
Whereas 9FA turbine have LCI for cranking, have lift oil for turbine bearings, unlike 9E is having only bearing only at the extreme end of the compressor and turbine and generator is hydrogen cooled. 

Answer / santosh dhange

9FA is higher version then 9 E
GE frame 9E means - 9 is the Frame size. E -Class or version.
GE frame 9FA - 9 means frame size, F - means Class, A- means annular Combustion type.
