Overview
When a power plant is not in operation, many components within the plant are subject to corrosion. This is referred to as standby corrosion. A plant may be shut down due to planned or unplanned maintenance, or due to low seasonal power demand. Power plants have to be idled or shut down temporarily due to following reasons:
- Maintenance or repair
- In case of breakdown
- Partial shut down due to excess capacity
- Extended cold standby (ECS)
Power plants have expensive auxiliary equipment that is subject to damage if measures are not taken to maintain relative humidity and prevent it from moisture which causes corrosion. As a rule of thumb, it is best to maintain relative humidity levels at or below 35% RH to slow down the rate of corrosion.
