Dear all,

In general,do we always have to consider shelter for compressors?

In special case,can we ignore shelter for GTC (gas turbine compressor) because the stack completely falls below the shelter?

Thanks

I have done FEED for gas turbine inlet gas compressor and there was no mention of any special shelter for Compressor. Reason being that the compression unit was being installed under roof.

I can state that I have never seen any process compressor that was not located beneath some sort of shelter. While we can all imagine various reasons for this, I cannot think of why I would not want my compressor under cover (except for the cost which is not that much). That should apply to the special case of a GTC as well. After all, the air inlet is still located outdoors.

Precise paying attention to my problem in my first post:"Designed stack completely falls below the shelter"

Compressor and gas turbine being as a package (means close to each other):
Isn't that problem so enough to think about possibility of not considering the shelter?

fallah,
Do I understand you to mean that the stack is within the confines of your building? That certainly is not right; obviously the flue gases must be exhausted outside the building. I don't understand why there would not be in place an exhaust duct that conveys those gases through the building wall and to an outdoor stack.

Djack,

Thanks for your reply,but there isn't any building and the whole compact package of GTC is considered under shelter.Considering this matter kindly submit your solution regarding our problem.

There is not necessarily any problem with what (I understand you to) have. The only requirement is that flue gases are not confined and that air can freely enter the intake of the GT. So long as these objectives are achieved, all should be fine. But again, what I have seen is that an intake enclosure (basically just a large filter) and the exhaust stack were NOT under cover; the GT and driven equipment should be under cover.
