WHITE PAPER:
Innovative Solutions to address Lube Varnish in Hydrogen Seals
Hydrogen seal failures can be very costly to large frame gas turbine users. The problem can either begin with the installation of bolted seals or the increase of varnish in the turbine oil, both of which will lower the dynamic clearances in the seals. This paper addresses some of the factors that lead to hydrogen seal failures and presents some solutions to address this problem.
