GAS TURBINES

Turbine Oil

Particulate and water reduce turbine oil viscosity, degrade turbine oil properties, and elevate turbine oil system operating temperatures.  In addition, particulate and water are catalysts in forming highly corrosive byproducts within turbine oil, and these byproducts attack bearing surfaces and other rotating components.  To protect sizable combustion turbine investments it is vital to keep turbine oil clean and free of water. 

Kaydon Filtration has experience in turbine oil conditioning for combustion turbines.  Our Turbo-TOC® turbine oil conditioning systems reliably removes both water and particulates.  Kaydon Filtration has helped several gas turbine power generators protect their equipment and maximize the effectiveness of their turbine oil. 

Compared to steam turbines, gas turbines do not normally need dedicated turbine oil conditioning systems applied to each reservoir.  However, water will invade gas turbine lube oil reservoirs, and effective oil conditioning equipment is needed to remove water before it can create water related damage.  Kaydon offers the KL5S2, KL10S2, and KL30S2 Turbo-TOC® turbine oil conditioners in a portable configuration.  These configurations include the skid mounted system with four casters and tow bar for effortless moving and easy positioning to a gas turbine lube oil reservoir.  By providing a portable unit, turbine oil can be conditioned for several gas turbines within a power generation facility.   Below is a general recommendation chart:

Diesel Fuel

When diesel fuel is used as the fuel for a gas turbine, one key issue faced by gas turbine users is treatment of diesel fuel prior to injection into the gas turbine combustion chamber. Water contaminated fuel causes incomplete combustion, which produces power loss and ignition “flame out”. 

 Also, saltwater contamination will cause sodium to enter the turbine, and this can lead to corrosive damage of the combustor and turbine blades. Particulate normally invades from corroded fuel tanks and fuel lines, and from poor fuel handling transfer and storage practices. Particle contamination of diesel fuel entering the combustor must be kept to a minimum to avoid nozzle plugging and combustion chamber fouling, in addition to reducing wear to moving fuel system components. Each gas turbine manufacturer has strict contamination limits, and the responsibility to comply lies with the power plant. Meeting the contamination limits can only be accomplished with fuel purification equipment that addresses both particulate and water.

The Kaydon VKS particulate filtration vessels and 851E diesel fuel/water separator vessels piped in series provide a complete solution to diesel fuel purification for gas turbines that use diesel fuel for either the primary or secondary fuel source.  Combined together, the VKS and 851E provide a diesel fuel purification solution for gas turbine operators.  

 
Turbo-TOC® systems are excellent choices for adding a further level of cleanliness for gas turbine lube oils.  When used on a regular rotating basis for multiple gas turbine lube oil reservoirs, the Turbo-TOC® brings an extra degree of turbine oil cleanliness.
        
The 851E diesel fuel/water separator vessels are designed and constructed in accordance with ASME Code and engineered to remove water from diesel fuel in a fuel forwarding line for a gas turbine.
 

        
The VKS series ofparticulate filtration vessels are carbon steel ASME Code constructed vessels designed for in-line filtration in a diesel fuel forwarding line for a gas turbine.  When combined as a pre-filtration stage before an 851E diesel fuel/water separator, the combination provide a complete diesel fuel purification solution.
