The Main Air Ejectors serve the critical function of maintaining a vacuum in the main condensers of a ship's propulsion system. This vacuum is essential for ensuring the efficient operation of the steam cycle, as it allows for effective heat exchange by facilitating the condensation of steam back into water after it has passed through the turbines. By keeping the condensers under vacuum, the Main Air Ejectors help minimize the amount of energy needed to move water and steam through the system and enhance overall thermal efficiency.

Maintaining a proper vacuum in the main condensers prevents back pressure from building up, which can hinder the performance of the propulsion system and lead to reduced operational efficiency. This operation is crucial for the overall functionality and effectiveness of the ship's propulsion and steam generation systems.
