TACKLING VARNISH FORMATION TO HELP MAXIMISE TURBINE PERFORMANCE

For turbomachinery operators in the power generation sector, finding ways to reduce total cost of ownership and maintenance costs by maximising asset availability and reliability is a top priority.

Understanding and controlling the rate at which turbine oils degrade, and dealing with the by-products formed, are vital steps toward maximising turbomachinery availability. 

Varnish: Understanding the Issue 

The operating conditions and equipment design changes of todays combined-cycle and gas turbines place additional oxidative and thermal stress on turbine oil that can result in premature ageing and degradation.

The formation of oil-soluble and oil-insoluble degradation products, also referred to as varnish or deposits, can lead to operational problems and associated unplanned downtime.

Tackling varnish can help reduce total cost of ownership and maximise turbine availability

Regular oil condition monitoring, varnish removal techniques and system flushing and cleaning procedures during oil changeover can help reduce total cost of ownership and maximise equipment availability.

To help you better understand how, Shell Lubricants has developed this white paper Tackling Varnish Formation in Turbomachinery.  

The paper shares insights and tips around:

  • How todays turbomachinery operating conditions and equipment design place additional stress on the turbine oil
  • The turbine oil properties and specifications designed to help tackle varnish formation
  • In-service strategies to minimise the impact of varnish formation including the importance of effective turbine oil monitoring and analysis
