Surface condensers are essential components in many steam power plants, where they play a critical role in condensing steam back into water for reuse in the boiler. They do experience several common issues that can affect their efficiency and effectiveness.

Tube fouling occurs when unwanted substances accumulate on the inside of the condenser tubes. This buildup can significantly reduce the heat transfer efficiency and necessitates regular cleaning. Water leaks refer to any unintended escape of water from the condenser, which can compromise the system's operations and should be promptly addressed. Air leaks, likewise, are problematic as they can introduce air into the system, leading to decreased thermal performance and even potential corrosion of the condenser surfaces.

Vapor leaks, however, are less common in terms of surface condenser issues because the design of these condensers typically allows for efficient handling of steam and vapor. While they can occasionally occur, they are not as prevalent or impactful as the other issues listed. This distinction makes vapor leaks an uncommon issue associated with surface condensers compared to the more frequent problems of tube fouling, water leaks, and air leaks.
