My apologies if this the not the right thread for this topic 1st
Greeting,
We currently have a Waste Heat Recovery Unit (WHRU) System to recover heat from a Gas Turbine Generator (GTG). Equipped with a multi louver and sealing air blower.
Current our client want to continue dry run the WHRU, keep the GTG running except for major scenario like tube leak, then we have to shutdown the GTG. This is due to the GTG of course being of main source of energy in whole system.
However our higher up want to to also shutdown the GTG whenever isolate Heat Transfer Oil.
I have read through ISO 21905 prat 9.3.2.2, it only mention case of tube bundle have to be designed for dry-run in case of unable to shutdown GTG AND not 100% fully isolate Heat Transfer Oil. Reason for not fully isolate even with damper + sealing blower is unclear to me, but suggested due to backflow or radiation. There are confirmation from MNF that the tube bundle is designed for GTG temperature / dry-run. This is a bit conflict of why our boss want to shutdown the GTG, but the reason is unknown for me at least.
Therefore i would love there is any ideas/ opinion on whether to keep the GTG running when isolate is better, if there is any big advantage for turning off the GTG when isolate the Heat Trasnfer Oil , safety reason included
