Online treatment of small air-cooled leaks
Thread Content
I would like to ask the experienced experts on this forum: if there are small leakage points at the base of the heat exchange fins of a steam turbine’s air-cooling system, are there any effective emergency solutions that can be used without shutting down the turbine? I would appreciate any useful advice you can share. Thank you!
It’s difficult to handle without shutting down the system; what is the medium inside your pipeline, what is the pressure, and welding under pressure presents challenges
Is it direct air cooling? Has the leak been found? If direct air cooling is used for condensing the turbine exhaust steam, the brazing process can be tried at high back pressure.
