Hello Everyone,
We have GE Frame 9E units (open cycle) with MARKVIe control system. Everytime during startup when machine reaches 95% rpm both 88TK-1 & 88TK-2 starts with a gap of 10 seconds. During this 10 seconds two things happen:
1) Sometimes the two flames go out immediately and after few seconds third one too. The unit trips on Loss of flame in between these 10 seconds.
2) Sometimes GT's rpm start decreasing from 2850 to 2760 & then after 10 seconds when the second Fan starts rpm start increasing up to FSNL.
Has anyone experienced these scenarios before? Why machine trips on Loss of Flame during this time?
