Best practices for maintenance of FRF in turbine EHC system
What is a Turbine EH System ? The most vital equipment of a power plant is the Electro-Hydraulic Control system (EHC system) of a turbine. It is the very soul of a turbine that directs steam into the turbine. An EHC failure can stop the turbine and then set off a series of events that will ultimately synchronize all processes in the power plant. The manager responsible for Operation & Maintenance finds it most challenging to keep the EHC system breakdown-free and operating reliably. Since there is high steam pressure & temperature surrounding a steam turbine from a safety compliance perspective, it is mandatory to use Fire Resistant Fluids (FRF) for hydraulic control of the EHC system. A synthetic fluid with chemical tri-xylenyl phosphate ester, specially designed for the application, provides the most exposure to fire resistance. Polar fluids, such as phosphate esters, are not only efficient for lubricating under harsh conditions but also exhibit a high-performance range....
