Where is the cooling water flow from an air ejector intercondenser and aftercondenser discharged?

The cooling water flow from an air ejector intercondenser and aftercondenser is discharged into the condensate and feed system because this system is designed to handle and recycle the water used in the cooling process.

In systems where condensers are employed, the cooling water absorbs heat from the steam or vapor being condensed, raising its temperature as it passes through. After this process, the cooled condensate is integral to the steam cycle, as it can be reused to generate more steam. By directing the cooling water into the condensate and feed system, the vessel maximizes efficiency in using its water resources, ensuring that it can maintain steam production while managing heat effectively.

Other options, such as directing the water to a cooling tower or wastewater treatment, do not align with the operational purpose of the condensate and feed system in a marine context, where recirculation of water is a priority for efficiency and conservation.
