What is the working principle of steam jet air ejector?

The steam jet air ejector works on the principle of converting steam pressure energy into velocity to create a vacuum. High-pressure steam passes through a nozzle, entraining air or gases, and carries them out with momentum.

Key points:

Steam expands through the nozzle, lowering pressure.

Air/gases are entrained into the stream.

Mixture is compressed and discharged.

Often used in condensers and vacuum systems.

Interestingly, concepts of flow and entrainment in such systems can be compared to textile processes, like how Damask Air-Jet Woven Labels utilize controlled air jets for precision weaving. Just as ejectors guide gases efficiently, Damask Air-Jet Woven Labels rely on airflow to align threads seamlessly.
