What construction method is commonly used for water-cooled division walls?

The commonly used construction method for water-cooled division walls is all-welded membrane construction. This method involves creating a continuous, sealed structure that can efficiently handle the thermal and pressure variations associated with cooling systems. The welded membrane allows for minimum thermal bridging and ensures that the coolant flows effectively, providing optimal heat exchange.

All-welded membrane construction is particularly advantageous in power engineering applications because it maintains structural integrity while minimizing the potential for leaks, which is crucial in a system where water is used for cooling. It also reduces the risk of corrosion, which can be a significant concern in environments where water and metals interact.

In contrast, other construction methods such as brick construction, metal mesh construction, and concrete encasement may not provide the same level of thermal efficiency or integrity required for effective cooling processes. While bricks can retain moisture and provide some insulation, they may not be as effective for direct water contact and cooling efficiency. Similarly, metal mesh construction might not have the necessary sealing properties to contain the cooling water. Concrete encasement often lacks the flexibility and sealing capabilities of welded membranes, which can lead to potential issues in a system that requires tight thermal management.
