steam turbine lube oil

 
In steam turbine power plants the steam turbine is the most important piece of machinery, generating the output of the power plant. The hot steam can be generated by coal, fossil fuels, nuclear power or HRSG (Heat Recovery Steam Generator). The steam turbines main lube system is typically the largest oil system in the power plant, which can contain upward of 40,000L of ISOVG46 oil, and is sensitive to water in oil, oxidation residues and particles. Therefore the oil in steam turbine lubrication systems must be clean and dry.

Challenge
If the steam turbine lube system oil is not kept clean and dry, you risk very expensive repairs or replacements, and downtime of the plant. The main problem with the steam turbine lube oil is water ingress due to leakage through the labyrinth seals, but also condensed water in the tank and particles are challenging. In new turbines, the settling-in time means increased particles in the oil, and this can cause immediate wear if particles are not effectively removed.  If the steam turbine does not perform, power is not delivered to the grid, and the risk of penalties arise.   

Benefits, installing CJC® Oil Filters

• Protect your investment
• Optimise availability of the power plant
• Reduce risk of steam turbine repairs
• Reduce risk of unplanned breakdowns, outages and penalties 
• Reduced maintenance costs

When you install a CJC® Oil Filter solution on your steam turbine lubrication system, you get an oil filtration system with excellent water removal capability and the highest dirt holding capacity. This can offer cost savings and better reliability of equipment, and a higher output of your plant. Technically, CJC® is known for keeping oil clean, dry and without oxidation residues which has been documented over many years and in several steam turbine lube system installations. CJC® Oil Filtration solutions are installed in many power plants worldwide. When you choose CJC® Oil Filters, you ensure a long lifetime of the turbine, reduce maintenance and you avoid unplanned breakdowns.  And you can even monitor the condition of your system using the Oil Contamination Monitor (OCM).
