Let’s discuss it together
Thread Content
Let’s discuss: What are the functions of the small pipelines connected to the compressor volute? Some of them are used for venting to a flare, while others are used for venting to a sewer.
In the diagram, 11802.3.4 refers to the drainage of condensate from the unit, while P1P2 denotes the drainage of seal gas condensate.
Additional note: Using two separate lines instead of one is to prevent gas mixing due to potential internal leakage in the valves, which could affect the operation of the unit
On the volute: exhaust and condensate discharge, pressure balancing
How is this balanced gas circuit balanced?
Could you please explain it more clearly? Those two lines? Thank you
Both of these lines are for condensate drainage; they do not lead to the flare.
At the shaft seal, it may be necessary to discharge the sealed gas via a flare due to the need for gas tightness; the pyrolysis gas compressor on the casing is equipped with a water injection system, but it’s not entirely clear where the water is injected and what the exact mechanism is. I was wondering if there’s anyone experienced who could guide me?
Is there more detailed information on the aircraft crew? The media in the two places is different, that’s why they are separated.
