| Reasons for a Fuel Oil Treatment System

Why to install a fuel oil treatment system with Westfalia Separator centrifuges?

Reasons

temperature corrosion

Increase the life time of the turbine

a es

Reduce the content of sediments

drastically

Latest approved centrifugal

technology with our OSD-Type

Customer Benefit: Reduction of

Corrosion on a turbine blade

| Reasons for a Fuel Oil Treatment System

The lifetime of turbine blades is depending on the sodium and potassium content

in the fuel

Lifetime of turbine blades

Mean lifetime of the blades:

8 - 12 years

Replacement of blades dependingon size of turbine costs several

million Euro

As temperatures increased due to demands for more efficiency,

it was found that the requirements of Sodium and Potassium levels

in the fuel must be reduce to smaller 1 to 0 1 m !!!

HFO normally contains higher levels of harmful trace elements such as sodium

and potassium

Efficient fuel oil treatment in power

plants ensures:

Attainment of the degree of purity

specified by the gas turbine

manufactures

Water-soluble trace metal elements

are reduced
