    Gas turbine

    Some may confuse "SOB" with Supervisor. Not mine of course. My supervisor's a swell guy! (He reads this site too).

    Going to Premix Mode from Lean Mode

    ahmad baktash, We simply went to the Control Constants Display on the HMI and made the changes for each MARK V. What do you mean when you state " We set the reference temperature (TTRF1) =1087 C for premix operation." Are you setting a Control Constant? What we were seeing on our units was...

    Going to Premix Mode from Lean Mode

    amahd baktash, We have six simple cycle 7EA's gas only units and we had this same problem on a few of our units in cold ambient temperatures. The problem was corrected by lowering the constant FXKTL2 by 10 degF - 15 degF. We change these every late Spring and late Autumn. We found if we leave...

    Asabula, Have you checked the Event Historian to see if any commands came from the DCS? If any commands were sent via logic or operator actions, it should show up here (from any control screen click Select>Event Historian). The only other thing I could think of real quick would be maybe some...

    Eliminate "coast-down to firing speed"?

    Hi CSA, Couldn't you open the IGV's at startup to increase airflow and reduce the purge speed? This would reduce ramp up and ramp down time, and maybe even the purge time itself. Someone would have to do the calculation to see how low you could go and still move the same amount of air.
