Question 171Steam Plants - QMED

The correct answer is A) main condenser. After the steam leaves the low-pressure turbine, it enters the main condenser, where the steam is condensed into water. This process helps maintain the vacuum necessary for the efficient operation of the turbine. The other options are incorrect because they do not represent the next step in the steam cycle after the low-pressure turbine. The turbine extraction valve manifold, feed and filter tank, and first-stage feed water heater are part of other systems within the overall steam plant, but they do not directly receive the steam from the low-pressure turbine.
