We have TM25000 on which the flame sensors at low loads are detecting a flameout despite other instrumentation (FGV, T54) suggesting otherwise. We are using Spectra GT30 flame sensors with self contained amplifier and 4-20mA signal. Has anyone come accross this problem before and what did you do to fix it?

If the exhaust thermocouples are reading even spreads and the redundant flame sensors are picking up the issue is specific to that device. It is possible the uv sensor is not picking up and needs to be cleaned or replaced. If your flame is truly flickering, it's time for a combustion tune.

We have a problem with our LM2500, whereby the load cannot be raised beyond 2MW (out of 20MW). We have exhausted all possibilities including changing the fuel pump, removing the filter, etc but to no avail. Has anyone come across the same problem before? TQ.
