Standard Guide for Microbial Contamination and Biodeterioration in Turbine Oils and Turbine Oil Systems

Importancia y uso:

5.1 This guide provides information addressing the conditions that lead to turbine oil microbial contamination and biodeterioration, the general characteristics of and strategies for controlling microbial contamination. It compliments and amplifies information provided in Practices D4378 and D6224 on condition monitoring of lubricating oils.

5.2 This guide focuses on microbial contamination in turbine oils and power generation turbine oil systems. Uncontrolled microbial contamination in turbine oils and lubrication systems remains a largely unrecognized but potentially costly problem in power generation systems.

5.2.1 Examples of turbine oil and system biodeterioration include, but are not limited to:

5.2.1.1 Filter plugging,

5.2.1.2 Oil line and orifice fouling,

5.2.1.3 Increased oil acidity,

5.2.1.4 Increased oil corrosivity,

5.2.1.5 Oil additive depletion,

5.2.1.6 Water emulsification,

5.2.1.7 Lubricity loss, and

5.2.1.8 Decreased oxidative stability and increased sludge generation.

5.3 This guide introduces the fundamental concepts of turbine oil microbiology and biodeterioration control.

5.4 This guide provides personnel who are responsible for turbine oil system stewardship with the background necessary to make informed decisions regarding the possible economic or safety, or both, impact of microbial contamination in their products or systems.
