Hi everyone,
I have been working for gas turbine frame 6b, i severe some problem during start with fuel oil.
on August 2019, gas turbine are able to start with fuel oil but then trip since step synchronizing initiate. the alarm appear was "loss of flame"
after that try to start with several checking in liquid fuel distribution line, then re-start and facing the same failure.
then start using fuel gas, everything was fine. continue running on fuel gas until 2020.
on November 2020, gas turbine trip while running at base load then fuel gas pressure low-low, initiating fuel change over, then trip by "exhaust temperature high high". after that restart with fuel oil due to unavailable fuel gas, but failure to firing, there is no flame detected.
then do several checking on spark plug (good, able to sparking), flame detector (good, able to detect flame), main fuel pump/magnetic clutch (engage and spin), flow divider (good, since running pressure each line appear approx. 7~8 bar).
second time start with fuel oil,. still firing cannot succeed.
so wait for availability fuel gas, and running with it until today.
did anyone here known what is going on my fuel oil problem ?
regards,
Tresna
