What is the role of an air separator in a boiler system?

An air separator plays a crucial role in a boiler system by removing air and gases, such as nitrogen and carbon dioxide, from the water circulating within the system. The presence of air can cause various issues, such as reducing the efficiency of heat transfer, leading to corrosion in the boiler and piping, and creating noise and vibration in the system. By effectively removing these unwanted gases, the air separator helps maintain optimal system performance and efficiency, ensuring that the heating process is as effective as possible.

This process helps to create a more efficient heating system, as it allows for better heat distribution and reduces the risk of operational issues associated with trapped air. Thus, the correct choice is the one that reflects this critical function of the air separator.
