Frame 5 Gas Turbine with Mark V control system Flames out at …
Oct 8, 2024 · A GE-design Frame 5 heavy duty gas turbine usually has between 2 and 4 flame detectors depending on the age of the machine and the type of combustion system (conventional or DLN), AND the Mark* won't usually trip the machine on LOSS OF FLAME until AFTER the warm-up period is over (which is about 1 minute after flame was originally detected).

GE Frame 5 Gas Turbine Inlet Filter Cleaning - Control.com
Mar 22, 2023. #1. Greetings All, Cleaning the Air Inlet Filters of the GE Frame 5 Gas Turbine with Pressured Air and Running water is time-consuming, which is done independently until the 288 Filters are cleaned. We are presently in need of other means of cleaning the Filters in a better way and less time-consuming before total replacement.
Gas Turbine GE frame 5 Start Up - Control.com
Jan 20, 2019 · For a Frame 5- or Frame 6 GE-design heavy duty gas turbine the liquid fuel bypass valve (if the unit was produced in the 1980s or after) would NOT have LVDTs), but the GCV would--and if it was calibrated improperly it might require that kind of reference for firing, and/or if the fuel being burned was low BTU fuel or something like that.
GE Frame-5 Gas turbine Ratcheting system Hydraulic pressure low …
Feb 21, 2023 · Now, GE-design Frame 5 heavy duty gas turbine shafts are relatively light and the bearings are filled with oil which makes them relatively easy to turn. The turbine output shaft is coupled to the input shaft of the reduction (load) gear box, and the output shaft of the load gear box is coupled to the drive end of the generator rotor.
GT Frame 5 Startup Procedure Clarification - Control.com
Jul 5, 2016 · Ours is Gas turbine frame-5 machine. During start-up the machine can be started in crank/fire/auto mode or directly auto mode. During crank start-up, diesel engine speed is reaching 1800 rpm and slowly reducing to 1500rpm and hence turbine is unable to reach crank speed i.e 920 rpm or 18% of rated speed. But once machine is started directly in ...
