What is a characteristic of a surface condenser used in condensing turbines?

A surface condenser used in condensing turbines is characterized by its construction, which typically comprises thousands of small tubes. These tubes are designed to maximize the surface area available for heat exchange, allowing the steam from the turbine to condense efficiently as it comes into contact with the cooler water circulating through the tubes. The effectiveness of this design is crucial for maintaining the efficiency of the turbine and ensuring that the waste heat is effectively removed.

Using numerous small tubes rather than one large tube improves the efficiency of heat transfer and ensures that the steam condenses properly, allowing the condensed water to be reused in the system. This design also helps to minimize the risk of fouling and scaling, both of which can occur in large-diameter tubes if not managed properly.
