ENGINE WASHING

ENGINE WASHING

• Atmospheric pollutants may contaminate the engine gas path, leading to a buildup of deposit on airfoils or the initiation of corrosion, sulphidation, or performance deterioration.

These effects can be alleviated with engine washing.

• Compressor Desalination Wash Used to remove salt deposits, which can cause corrosion, drinking quality water injected into the engine intake using either an installed compressor wash ring or a handheld wash wand.

• Compressor Turbine Desalination Wash Used to remove salt deposits from compressor turbine blades and stators which can cause sulphidation a reaction between salt in the atmosphere and sulfur in fuel.
• this wash must be done immediately following compressor desalination or performance recovery wash as contamination will be transferred from the compressor to the section.
• wash fluid is drinking-quality water.
• water is injected through a wash tube inserted in one of the igniter ports.

• Compressor Performance Recovery Wash Used to remove stubborn deposits that are unable to the removed during normal desalination washes
• wash fluid includes an approved detergent.
• only be done by when engine performance is lost noticeably.
