Many units in the combined cycle setup, which can be comprised of two MS7001FA gas turbines and a D11 steam turbine, are also equipped with 7FH2 generators. Many of these machines have unbolted babbitted hydrogen seals. If there’s any contamination of the oil or improper assembly, those conditions may cause the unbolted seals to tilt, which could lead to a hydrogen leakage and oil ingress into the generator. MD&A upgraded a customer’s hydrogen seals for a 7FH2 generator by modifying the existing housing.
In the power generation industry, most large generators are cooled by hydrogen gas. If a unit will be offline for a while for a planned maintenance outage, the hydrogen must be removed. MD&A Control Systems has a strategic partnership with Lectrodryer® to perform installation and commissioning services for their Generator Automated Hydrogen Purge Package. Give your plant the best possible solution with a minimum of oversight by combining the proven Lectrodryer® Package with MD&A’s experience on generator auxiliary systems’ operation and maintenance.
MD&A Parts Division's Advanced Sealing system for steam turbines, consists of the Patented Guardian® & Vortex Shedder® Sealing Technology which improves steam turbine efficiency above design!
