Why is it advisable to keep moisture in the inlet low as possible in a steam turbine?

Keeping moisture in the inlet of a steam turbine as low as possible is critical because it minimizes turbine blades wear. When steam contains high levels of moisture, it can lead to a phenomenon known as "wet steam" or "saturation," where water droplets collide with the turbine blades during operation. These impacts can erode the blades over time, leading to reduced efficiency, increased maintenance requirements, and ultimately, a shorter lifespan of the turbine.

In addition to reducing wear, minimizing moisture ensures that the steam is as dry and superheated as possible, which contributes to more effective energy conversion and overall turbine performance. While functions like reducing noise and optimizing fuel consumption may be important aspects of turbine operation, the direct impact on wear due to moisture makes it particularly critical to manage moisture levels effectively.
