Have you thought about how to isolate individual CT's from the HRSG when down or maintenance is required? How would you handle fluctuating loads? GT's don't like running at partial load, so prudent operation would be to take one or more off line and leave the ramaning one(s) run at higher...
Some of the "old school" methodology was just blind stupid luck. I inadvertantly tripped a unit on an islanded systemconsisting of two plants, multiple units at each plant, but only one unit running at each plant that winter evening. The operator at the other plant just happened to be up...
As Scotty has noted, combustion turbines come in "hot end drive" and "cold end drive." The words you quote to me say to me that this is a cold end drive machine. The LM-6000 was mentioned in another thread witin the last few days. It is a 'cold end' drive machine. Large "F" frame machines...
I think your temperature measuring element is being wetted by carryover or ME slip, thereby cooling it below the sat temp of the vessel. Is it possible to move it?
Or... the 'purified' water is loaded with air or some other dissolved gas so that as was stated much earlier in this thread, there...
So, is the effect you are asking about in the original post the first effect? Define 'purified water'. Are you distilling purified water or making purified water, and if making purified water, what are you distilling. What is the boiling point elevation (depression) of the fluid that is fed...
My main experience with basalt lined pipe was in coal bottom ash slurries and that flow stream is full of clinkers that are not only lava hard, but with lots of sharp edges too. Some of the pumps that pumped the stuff were designed to handle up to 14" solids. It was very tough stuff, not...
Air meaning any form of non condensables. EM, Hopper has asked a legitimate question for this thread. Shoubaki, two possibilities, one is non-condensables where the partial pressure of the water vapor has to be taken into consideratoin or (2) if this temperature sensing device is in fact above...
There is an Automotive Lubricant forum in the Automotive section that I think you will find more posters who might be able to help you, not that it isn't a ME subject. The members who lurk there might have it at their fingertips.

I have used beaucoup chrome carbide plate as fan and ductwork liners for gas sterams laden with abrasive materials - and it was just dandy. Those however, were dry processes where the...
A hot lay up boiler connotes to me a boiler ready at a moment's notice to come on line and take up the slack if, for example, another boiler should trip. Can it have happened that this boiler has been called on to come to full load in a rapid fashion without the SH loops having been properly...
I don't know exactly how to recommend the search terms, but a search of this site would reveal this topic having been discussed many many times. I'd recommend you make some kind of attempt to find some of those older conversations. I know there is information in there that you are looking for...
I meant to say "...in series with a trap.." in my earlier post.
To add to moltenmetal's comment above, it also allows full steam pressure (which has a temperature relationship) in the Hx rather than a reduced pressure across a control valve at the inlet, and for some Hx's or processes, that is...
I think it has been repeated several times throughout this thread that it is NOT the right thing to do to have a control and valve in series after a heat exchanger. To do so is a poor design. Are you trying to justify the design?

The relationship is this: Q = M(dot)*Cp* delta T. But also, Q = M(dot)*U*A*LMTD. The first is a heat in/heat out book keeping equation and he second is a function of the heat transfer coefficients and the terminal temperature differences.
So you need to know how much heat you need to remove...
I am familiar with the concept of a control valve on the condensate outlet, but that is not the question that was asked in the OP. Adding a trap in series after the valve makes it into a completely different situation.
On the second method mentioned above, if the control valve fails shut...
