Application Of Dry Gas Seals In Special Purpose Steam Turbines.
Abstract
Noncontacting dry gas mechanical face seals are being routinely
applied to steam turbines to reduce new construction project costs
and improve overall plant operating efficiencies. Historically, most
of the applications have been in general purpose turbines. On a
recent California refinery expansion project, this innovative seal
design was selected for two special purpose steam turbines.
Concurrently, a similar turbine for another customer had similar
operating conditions and design challenges.
During turbine testing, the seals failed. An extensive root cause
failure analysis determined that material face combination and
operating procedures were the sources of the failures. With the
change in materials and procedure, both turbines and three sets of
revised seals passed a series of API tests, including a partial load
test run. In the fall of 1996, the two turbines were commissioned
and have been in operation since.
