Your main problem will be at light off, when you have the highest wobbe index. Remember this is a fixed GCV stroke setpoint. It would be worth contacting GE for some advice, maybe you can get away with it as you are only slightly above the maximum index number or maybe you can change the gas...

I don't know which turbines you are using but I can talk GE industrial machines, but I reckon it is pretty much the same for all. The fuel gas regulating system is normally set up according to a gas specification supplied by the customer at the time of ordering. This system will accept small...

I reckon that the strange noise that you are hearing is VR5 relieving (Is it a loud squealing noise?). Try removing VR5 and checking Its setting. If it is too low you will be short of operating pressure, from memory, it is set at around 90 Bar.

You don't have a Ground brush on your rotor?

The ratchet control module has what I guess you could call a mechanical flip-flop valve which is controlled by the forward and reverse stroke piston oil. In forward stroke, the ratchet has a mechanical device which grabs the shaft and rotates it, in reverse stroke the mechanism free wheels (like...

Before I answer, I think if you use the Search box in the top right corner of the forum and search for "Temperature Control" you should find some relevant information, it's been discussed many times before. If you don't get an answer, reply back

You Email address is not working, should it have .com on the end?

Normally VPR-1 is a relief valve but a proportional valve. It doesn't have a diaphragm and will fail to close, but BHEL sometimes do some strange things. VPR-2 should be sensing the Bearing Header pressure and can be installed to dump excess pressure to the tank on some machines. As CSA says...

I could take some time and give you an answer on the forum. But if you can give me an email address, I can send you a Control Specification for a GE machine which will give you all your answers and more.

I think that he is talking about Chemical Oxygen Demand but it would be good if the writer would confirm!!

Try this, it is the best that I can find. Hope it helps There are 1000mg in 1g, 1000g in 1kg, and 1000kg in 1t. There are 1000L in 1m³. There are 3600 seconds in an hour and 24 hours in a day (if you run continuously) Your concentration in mg/L is the same as your grams/m³. To...

Well, I guess this is a BHEL invention. Why they use a pump with separate LO system I don't know. I would guess that you could use a "normal" Fuel Oil pump but that is a huge job. You need to look at why the DC pump logic is wrong, maybe that is what is causing your problem. Where you located?

Looks like the solenoid is controlling the return to tank flow back to the tank depending on the return line pressure. Can you show the logic for the operation of the solenoid. Have you talked to BHEL about this?

Is this really a GE Frame 5 with an Off Base L.O. skid? First I've ever seen. Can you upload some Flow Diags. to somewhere?

It kind of looks like you don't understand how DLN1 works! Is there someone there who does? There are a lot of documents on the operation of DLN, you should have some in your manuals,do you?

What model is the turbine? If it is an Aero-Derivative (LM series) it can have a lockout before restart.

Hi CSA, I was just about to post something similar. The thing that is very strange from the data sent is the cooling water temp. before and after the cooler, the temp. rise of the water over the cooler seems very small for a machine which is running such a hot AA Temp.

Interesting question but really the answer is, there is no other way, but a few questions :- 1) Is the VTR-2 controlling the AA cooling water wide open? If not, manually open the valve to see if the temperature improves. 2) What is the Air temp. going into the heat exchanger? 3) What is the...

There should be no problem changing over hydraulic filters on a running machine. But, if you think that you have a transfer valve problem, you need to be careful. 1) Can you take a shutdown and try to repair the transfer valve? 2) What is the differential pressure on the running filter...

This is Control.com, the documents I have are for control systems. If you don't understand how an LNG plant works, I think that you need to ask your Employer (RAS Gas?) to get you some training.
