The term 'loss of water seal in the hotwell' primarily affects which system aspect?

The term 'loss of water seal in the hotwell' is primarily related to vacuum maintenance. In systems that utilize hotwells, a water seal is essential for maintaining the vacuum that is necessary for efficient operation, especially in condensate systems. When the water seal is compromised or lost, it can lead to air ingress into the system, which can disrupt the vacuum.

Maintaining a proper vacuum is crucial for the optimal performance of heat exchangers and condensers. A loss of vacuum can result in decreased thermal efficiency and potential operational issues. Without a proper seal, the system may have to work harder to achieve the necessary conditions, thereby affecting overall efficiency and reliability.

Other aspects like water filtration, pressure regulation, and cooling capacity are important system functions, but they are not directly impacted by the loss of water seal in the hotwell as much as vacuum maintenance is. Issues in these areas can arise as secondary effects of poor vacuum conditions, but the primary concern is the maintenance of the vacuum itself.
