Why is superheated steam considered more useful than dry saturated steam?

Superheated steam is considered more useful than dry saturated steam primarily because it has absorbed more sensible heat. This additional heat increases the overall energy content of the steam, allowing it to generate more energy when expanded in a turbine or used for heating processes. The increased temperature of superheated steam means that it can perform more mechanical work when it passes through turbines, as it can expand more significantly without condensing.

In contrast to saturated steam, which exists at a specific temperature and pressure and can condense upon performing work, superheated steam remains in a gaseous state even at lower pressures, providing more efficient energy transfer and reducing the risk of water droplets forming that could damage equipment. The capacity to carry more heat makes superheated steam advantageous for applications requiring high efficiency.
