How are by-products formed and how will this effect the rate turbine oil degrades?
Understanding how varnishes are formed allows turbomachinery operators to make an informed choice of the best maintenance regime for their equipment.
High variable temperatures, oxidation rates, thermal degradation and generation of contaminants can increase the total acid number, which over time develops into insoluble polar compounds that then creates varnish deposits.
This is something that operators need to consider when choosing turbine oil for their machinery, as oil can provide increased resistance to the formation of varnish deposits.
