Question 62Steam Plants - QMED

The correct answer is D) reduce the effects of electrolysis. Zincs are installed in the main and auxiliary condenser water boxes to reduce the effects of electrolysis. Electrolysis can occur in the condenser when dissimilar metals are in contact with each other in the presence of an electrolyte, such as seawater. The zinc acts as a sacrificial anode, meaning it corrodes preferentially to the other metals in the system, protecting them from galvanic corrosion. The other options are incorrect because they do not accurately describe the primary purpose of zincs in the condenser. Preventing air pockets, scaling, and reducing turbulence are not the main functions of zincs in this application.
