Power generation companies are often contractually obligated to deliver a certain amount of power over a certain amount of time. They are currently facing multiple simultaneous challenges: the reduction in the use of coal, the reduction in the use of nuclear power and the increased use of renewable energy sources such as solar and wind energy, which are not always available on demand. They also must be ready to activate peaking units instantly when demand spikes.
Varnish created by lubricant oxidation in a turbine can cause gas regulation valves to stick and impair oil cooler performance, resulting in serious operational issues or, in the worst case-scenario, in automatic shutdown or failure to start. Not surprisingly, therefore, varnish resistance is a hot topic in the turbine world.
