Season's Greetings!
Pls. be informed that we are facing the Gas turbine (Solar) Trip on "High Start Gas Fuel Flow", during start-up of the machine with in approx..8- 10 Sec. after the Purge time step is completed.
Alarm Grp. name: FSNL ,
Tag name: FN_High_Start_Fuel_Flow,
Following are the observations:
Main Fuel Gas Pressure: 24.1 Bar (350 Psig)
Primary Shutoff Valve opens
Secondary Shutoff Valve opens
Gas Torch valve opens
Igniter becomes - ON
ECT Avg. reading visually noticed reached to 240 deg. C for a very short time. The trend plotted it at 45 deg C only.
Fuel Gas flow remains at Zero at this stage. This reading reaches to 250 momentarily during Gas Fuel Control Pressure check step.
Main Fuel Gas Valve command reaches till 6%
Main Fuel gas Valve position feed back achieved 6%
Action taken :
Torch Gas Pri. regulator out put was checked and found at 35 psig,
Torch Gas Sec. regulator output checked and found at 24 psig.
Kindly advise the way forward.
