I don't disagree with Bob Peterson's last sentence, having been there and done that. Everyone's interpretation of TMR is slightly different. Everyone's application of TMR is slightly different. I would imagine there are subtle, as well as significant, differences between Siemens, and GE's...

No worries about the English skills, I think we're understanding you reasonably well. It's a well-documented fact that any PC (any motherboard/microprocessor/BIOS) can be used to run MS-DOS and IDOS to allow the PC to become an <I> GE Mark V operator interface. In fact, many newer...

Thanks for the feedback, but I'm still not clear on precisely what you're trying to do. You came in this thread pretty late, and we don't have any idea of what kind of operator interface your site has, nor what versions of IDOS or TCI and MS-Windows/CIMPLICITY the site is running. Not every...

Dear Gent, Off-line water washing is just like putting your clothes in an "automatic" washing machine. Sometimes the clothes have more dirt than others or the dirt/stains are of a different nature than usual. Sometimes a little extra detergent, applied directly to stains, is appropriate...

It would appear that the OEM who told you this was possible was at least partially incorrect. The only reason I can offer for the damage you are seeing is that the temperatures in the area of the AA cone tip are just too high. Is it that there is no air ("purge") air flowing through the AA...

Teekay/MIKEVI, The servo gain and null bias can be obtained from the I/O Configurator on the operator interface (I don't think we know if it's an <I> running IDOS or a GE Mark V HMI running MS-Windows and CIMPLICITY--but we should, be told, that is). And you will need to use the operator...

Please tell us more about the ARCnet card you installed to replace the previous ARCnet card. Who is the manufacturer and what is the model number of the new ARCnet card? Who is the manufacturer and what is the model number of the previous ARCnet card? Did the card look like the one...

Advice was offered on how to possibly correct whatever situation was caused by the unnecessary attempt to calibrate the "servos". I do understand why people think servos are calibrated, but it's just not true--it's a myth. And it's myths like these that cause problems like the original poster is...

Cris, Both are methods for decreasing the temperature of the air entering the axial compressor inlet, which increases the density of the air, which increases the mass flow of air through the axial compressor and turbine and therefore increases the power that can be produced by the gas...

Well said, MIKEVI!!! It does seem to be the case at too many sites that alarms are just interpreted as nuisances and not viewed as the helpful indications they are or should be. It is also unfortunate that GE does not do a better job of documenting alarms, or providing written...

<b>From the information provided,</b> I'm not convinced the "burning" is caused by the lack of purge/cooling air. I believe that if you try what you've suggested you will most certainly create a path for the back-flow of hot combustion gases through the AA passages. As an alternative...

Demigrog, Everything you said is true. But the originator of the post doesn't want to communicate with Mark VIe control panels <b>through</b> any HMI or intermediate PC. He, and many others, want to communicate <b><i>DIRECTLY</b></i> with the Speedtronic (Mark V, Mark VI, or Mark VIe)...

309Eguy, Let's be clear about the order of events to be taken when replacing a servo-valve on a GE-design heavy duty gas turbine: 1) Make sure the Speedtronic null bias current value is set to 2.67% (for TMR Mark V, Mark VI, or Mark VIe Speedtronic turbine control panels). This may mean...

Hello, All of the HRSGs with supplemental firing that I've had the pleasure of working on were not designed to be supplementally fired when the gas turbine was at part load with the IGVs at minimum operating position. What does the HRSG manufacturer, and the supplemental burner...

Most of the VME cards and many of the I/O terminal boards requires 28 VDC for operation. Microprocessors (of which there are many), RAM, and other components (operational amplifiers; analog-to-digital and digital-to-analog converters; etc.) require +5 VDC and +12 VDC and +15 VDC for proper...

Teekay, I will take it that you took my comments personally, which was not intended. But, no matter what you call it, overlooking alarms is the same thing as ignoring them. Just resetting and continuing to push the START button without understanding every alarm is just wishing for good luck...

This is another perfect example of the myth that changing servo-valves requires calibration or re-calibration--of anything. A servo-valve is NOT calibrated; only the LVDT feedback from a device which is positioned by an electro-hydraulic servo-valve. And, if there are no LVDTs then the "valve"...

Thanks for the feedback!

I was taught that keeping the drum level around mid-level was important for several reasons. One, as has been said, to keep elements in the lower part of the drum covered with water and that prevents damage from excessive heat. Two, the surface area of the water is maximized when the water...

First, if you are finding "burning" of nozzle components, then replacing exhaust T/Cs probably wouldn't resolve the spread problem. Second, if the transmitter is 0-5 VDC, why can't you adjust the zero down to 0.0 VDC and the span (gain) to 5.0 VDC? How did the transmitter come to be...
