(Guide)Standard Guide for Cleaning, Flushing, and Purification of Steam, Gas, and Hydroelectric Turbine Lubrication Systems
Standard Guide for Cleaning, Flushing, and Purification of Steam, Gas, and Hydroelectric Turbine Lubrication Systems
SIGNIFICANCE AND USE
This guide is intended to aid the equipment manufacturer, installer, and turbine operator in coordinating their efforts to obtain and maintain clean lubrication and control systems.
The flushing and cleaning philosophies stated in this guide are applicable to both large and small lubrication systems.
Clean lubrication systems result from proper system design and good planning, execution, and communication by all involved during commissioning. No phase of these procedures should be undertaken without a thorough understanding of the possible effects of improper system preparation. The installation, cleaning, and flushing of the equipment should not be entrusted to persons lacking in experience.
Because of the knowledge and specialized equipment that is required, the operator may wish to employ an outside specialist contractor for the system flushing. Review of this guide can provide guidelines for discussion with prospective contractors.
SCOPE
1.1 This guide covers types of contaminants, oil purification devices, contamination monitoring, contamination control during building or refurbishing of turbine systems, lubrication system flushing, and maintenance of pure lubrication oil.
1.2 To obtain maximum operating life and reliability, or lubricants and system, it is vital that the turbine lubrication system has pure oil. This guide is intended to aid the equipment manufacturer, installer, and turbine operator in coordinating their efforts to obtain and maintain clean lubrication and control systems. These systems may be on land or marine turbine generators and propulsion and mechanical drive equipment. This guide is generalized due to variations in the type of equipment, builder's practices, and operating conditions.
1.3 This guide primarily addresses petroleum based lubricating oil. For systems using nonpetroleum based fluids, this guide may not be appropriate. For nonpetroleum products, consult the equipment and fluid manufacturers.
1.4 This guide is applicable to both large and small lubrication systems. Some equipment specified herein, however, may not be appropriate for all systems. Moreover, in situations where specific guidelines and procedures are provided by the equipment manufacturer, such procedures should take precedence over the recommendations of this guide.
1.5 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

INTRODUCTION
Optimum turbine system reliability requires a well designed lubricating system and use of a good
lubricant that is free of contaminants. Achieving this requires use of proper purification methods to
ensure that the oil is free of detrimental contaminants. In addition, it requires an ongoing monitoring
program to ensure that the oil quality is within specifications and that corrective action is taken to
minimize contaminant generation and ingression. The benefits of purification of an operating
lubrication system can be significantly reduced if the lubricating systems are not initially cleaned to
a level that will prevent component damage on initial start up after manufacturing or rebuilding.
Care and thorough cleaning are required to minimize and remove contaminants during fabrication,
rebuilding, or installation, or combination thereof. Because contaminants will remain from these
processes, it is necessary to flush and purify the system to remove them prior to startup. Ongoing
purification is required to maintain pure oil during operation. In new systems, the emphasis is on the
removal of contaminants introduced during manufacture, storage, field fabrication, and installation. In
operational systems, the emphasis is on the removal of contaminants that are generated or carried in
during operation, and by malfunctions that occur during operation or contaminants that are introduced
during overhaul, or both.
