AIR EJECTOR Meaning and
Definition
-
An air ejector is a device or mechanism that performs the task of emptying or extracting air or gases from a closed system or vessel. It is essentially a type of vacuum pump that uses the venturi effect to create suction and remove unwanted air or gases.
The air ejector consists of a few essential components including an inlet, a nozzle, a diffuser, and an outlet. The process begins with the flow of a high-pressure fluid or gas, typically steam or air, through the nozzle. This high-velocity fluid passes through the venturi, creating a strong suction at the inlet of the ejector. As a result, the air or gas present in the system is entrained and drawn into the ejector.
Once the air or gas is captured, the mixture continues through the diffuser, which gradually expands the flow area. This expansion causes a drop in velocity and an increase in pressure, forcing the extracted air or gas to be expelled through the outlet. The ejected air or gases are then discharged into the environment or redirected to a different part of the system.
Air ejectors find applications in various industries, such as power plants, petrochemical plants, refineries, and water treatment facilities. They are used for tasks like deaeration, degassing, vacuum creation, and maintaining a specific pressure range within a system. The efficiency of an air ejector is typically dependent on parameters like fluid flow rate, pressure drop, and the ratio of motive fluid to the extracted gas.

Etymology of AIR EJECTOR
The word "air ejector" has a relatively straightforward etymology. It combines two main components:
1. Air: The word "air" originates from the Middle English word "air" or "eyr", which was derived from the Old French word "air" and the Latin word "aer", both meaning "air" or "atmosphere".
2. Ejector: The word "ejector" comes from the verb "eject", which traces back to the Latin word "eicere", meaning "to cast out" or "throw out". From the verb, the noun "ejector" was formed, referring to a device or mechanism that ejects or expels something.
Therefore, the term "air ejector" refers to a device or mechanism used to expel or remove air from a system or specifically designed to discharge air to create a vacuum.
