Most corrosion specialists with experience in the power-generation industry suggest using a closed-loop system with generators to reduce humidity levels to 35% or lower. Doing so will help reduce corrosion. In addition, preventing corrosion due to foreign objects, such as salt, basically comes down to adhering to filtration methods properly.
Pipes should also be insulated with jackets or protective coatings. When appropriate, improving pipe design to have better flow characteristics can also aid in corrosion prevention. Protective coatings are a good idea on any component exposed to water, condensation, or the environment outdoors.
Often, the water in power plants contains chemicals or organic agents like anaerobic bacteria, so using a water-conditioning agent can be helpful. Other strategies include using drains or vacuums to prevent water from pooling and using dehumidifiers for air that passes through turbines to reduce relative humidity levels. These methods can often be adopted without spending inordinate sums of money.
It's little wonder then that power plant damages from erosion, corrosion, and foreign objects are a constant worry for power plant managers, especially as their plants approach the end of their design life. However, many of those worries can be reduced by undertaking an evaluation of current filtration policy and regularly inspecting at-risk components.
Perhaps the most obvious preventative remedy against power plant damages is a ruthless inspection regime that consistently tests components at risk from corrosion, even ones that have protective surfaces. Such components include turbines, pipes, ducts, areas with demineralized water, welded areas, and scrubber modules.
