Why should moisture in the inlet of a steam turbine be kept as low as possible?

Keeping moisture in the inlet of a steam turbine as low as possible is crucial primarily because of the potential wear it can cause to the turbine blades. In a steam turbine, the presence of water droplets can lead to erosion and damage to the blades due to the mechanical impact of the moisture. This damage can compromise the efficiency and longevity of the turbine, leading to increased maintenance requirements or even premature failure.

While factors like energy loss, boiler efficiency, and operational costs are important considerations in turbine operation, the direct relationship between moisture and blade wear is a primary concern. Reducing moisture not only extends the life of the turbine components but also helps maintain optimal performance and efficiency levels, contributing indirectly to lowering operational costs and enhancing overall system reliability.
