    Frame 9E dual fuel gas turbine with water injection as the nox control

    Hi All, We are currently running a frame 9e dual fuel gas turbine (as originally designed) with diesel fuel only. Although the turbine is designed for both gas fuel and diesel operation, it has never run in gas fuel due to unavailability of gas. Currently we are looking forward to receiving gas...

    Legacy Alstom Frame 6B gas Turbine Ventilation Fan 88BT

    Hi WTF, Thank you for the above information. I managed to get the model and the fan curve. It is designed for 3.6m3/s at -90mm h2o total head. Model is HMP 50-6-21VA from Solyvent Ventec. Also, one of the documents I read referred BT fan as pressurization fan and that confused me a lot. With...

    Header Pressure Low Switch and Transmitter of GE Frame 9E to Elin 9A5 Generator

    Hi Gents, Thanks for the reply and really appreciate it. I had no luck getting the PID from GE, but below is the diagram I could draw as per the layout. It is clear the porting valves should be in closed position and did verify with another site too. I will continue to upload if i receive the...

    Header Pressure Low Switch and Transmitter of GE Frame 9E to Elin 9A5 Generator

    Thanks CSA and Control Guy, Unfortunately P&ID is not available that is exactly what i am after. I can trace the lines, but due to limited space, i may need to remove couple of screws and front plate. what i have seen is it required to close two porting valves to establish the required pressure...

    Gas Turbine SRV Leak Observation

    Hi Makster, All of the SRV's I've worked with have a elastomer seat. If it does not seat properly, chances of further deterioration is also high. And soon after a shut down, you will be able to replace the seat within couple of hours while turbine in turning gear). In my opinion, it would be...

    GE Frame turbines Over Speed Testing

    Thanks MIKEVI and CSA. As an practical,doable and appropriate approach, we have selected 100% speed shutdown over speed test function (not yet implemented though). This is given the fact that no extra startup is required, turbine is fully heat soaked and trip can verify the function of all the...

    GE Frame turbines Over Speed Testing

    Hi MIKEVI, thanks again for the great inside. Apologies for not specific on my query. My question was more on comparison to a startup low setting test compared to shut down and on the selection of speed. for example, bringing the setting down to a low value like 55% speed is a doable in a...
