What is a potential consequence of starving a superheater of cooling steam?

Starving a superheater of cooling steam can lead to overheating and possible rupture of the superheater components. The purpose of the cooling steam in a superheater is to maintain an optimal temperature within the system and prevent the metal from reaching its maximum temperature limits. When this cooling steam supply is insufficient, the metal can become excessively hot, which can lead to thermal stresses, deterioration of material properties, and ultimately, a failure like rupturing of the tubing or components.

The integrity of the superheater is crucial for safe and efficient operation, and maintaining the correct temperature balance is a key factor in ensuring this. Without adequate cooling, not only does the risk of catastrophic failure increase, but it can also affect the overall efficiency and safety of the boiler system.

In contrast, other options such as increased efficiency or decreased output pressure do not accurately capture the consequences of insufficient cooling steam. Additionally, while reduction in steam quality may occur under certain conditions, the most immediate and critical risk is the potential for overheating and rupture.
