You say that you have some white smoke so it looks like you have fuel. Do you get any change in exhaust temp. when you try to fire? It would be nice to try a new set of fuel nozzles that have been calibrated, do you have any? You have checked a lot but I would still be a bit suspicious of the...

One bit of information you didn't give is what is the HP Fuel Pressure before the Flow Divider? If the pressures are different, the actual fuel flow could be the same. Do you have any other fuel flow meter installed anywhere on the system, even on the LP side?

Some more information would be useful. any pictures of bucket damage? How old is the machine? Fired Hrs. at overhaul? Any strange behaviour before shut-down? Any pre-shutdown data? Any of the above would be useful, we don't have a crystal ball out here!

It's pretty well up to the client to specify which way he wants to go. A lot of the decision is based on how you operate your plant and how you do your maintenance. With one HRSG/machine it means you can do turbine and boiler maintenance at the same time or maintain the HRSG with the turbine...

Don't take the radio near the pressure transmitter. What control system are you using?

Looks like a problem with Diesel Engine Lube Oil Pressure, probable tag is L63QD(N). This will stop engine accelerating with 20DA. Cannot remember the setting but > 9 psi sticks in my mind.

We see some very strange things on this forum sometimes! Do you guys have a Permit for Work system in place? If yes, how did anyone ever allow a permit to be issued to do this extremely dangerous job (As CSA commented, you are lucky you didn't kill someone). If you don't have a permit system, I...

Stall: When a compressor is operated away from its design point, the gas flow into the aerodynamic components (impellers, blades, diffusers, etc.) deviates from its design direction. If the angle of deviation (or incidence angle) is large, flow separation occurs. At higher incidence angles, the...

IGV should go fully closed on a trip, usually within 2 seconds to fully closed. This is to prevent a shut-down surge or choke.

Once you have entered the 5-digit password, you should have access to the Raise & Lower pushbuttons and can adjust the constant value (It will be very slow to adjust if you are online). Hope this helps

Normally extended ratchet cycle times are caused by not making the forward stroke and therefore never cycling 33HR so the system never gets reset and keeps trying to run to get 33HR to cycle (Forward & reverse stroke completed). Usually this is an operating pressure problem (Low). I would...

Just an addition to CSA's comments. GE's policy on DLN machines running in Extended Lean-Lean is 1 hour in Ext. L-L = 10 hours normal firing. This is how damaging they reckon running in Ext. L-L is. So, 5 months is 3,600 Hrs. = 36,000 Fired Hrs. It is just unbelievable how badly some people can...

Do you know if the 4 Kg/cm2 is according to spec? I have no experience of this particular torque converter on a Frame 3 but, normally on Frame 5 & 6, it should be at least 6 Kg. Have you checked the foot valve and trash screen on the torque converter?

Is this a Gas Fuel machine? Are you sure you have no fuel gas problems which could cause a possible liquid carry over in the gas system? Was fuel gas supply temperature OK Is there any chance that you are operating near the gas dew point? Was there any evidence of unusual levels in your Fuel Gas...

If T/C fails (open Circuit), it will read the minimum value in the scale code for the thermocouples, basically open circuit is 0 mv. The thermocouple will be rejected from the system and you will get an alarm indicating a failed thermocouple. There is no way to set failed hi or low, it will fail...

You didn't mention what type of air filtration system you are using. Self cleaning (Pulse jet) type filters can start to get very high pressure drops in high humidity or rain when the filter is beginning to get contaminated. You mentioned high diff. in the morning and getting better in the...

It is pretty clear that there is some problem with the governor/fuel control on the Iso machine that is hunting. Again, we really need more information on the machine, maintenance history, type of fuel, etc. If you can, please also send details when the machine is hunting, FSR, Load, Servo...

Are you sure that you are in the correct UNIT directory? It looks like MK5MAKE cannot find UNITDATA. Can you post the LOG file?

If you are not aware of it, the 2 middle digits on a turbine Model Name are the output Horsepower in thousands so a 6581 is 58,000 SHP. Exactly what other differences there is between the 56 and the 58, I don't know. If you need to know more than this, I have 6581 machines here and can send you...

Came into this discussion late. I don't know if it is any help to you but we are running an islanded system in an LNG plant where our 4 X MS6000 machines are using a PMS system (ABB ENMC). Our four machines all run in Droop with PMS doing the frequency control. I would think that this an easier...
