Mmmmm... why only steam is used in a steam ejector for creating vacuum and not anything like air or other inert gases...
Steam ejectors create a vacuum by using high-pressure steam to create a low-pressure zone. The steam is directed through a nozzle, which increases its velocity and decreases its pressure. This creates a suction that draws air or other gases out of the system, creating a vacuum.
The principle behind steam ejectors is called the Venturi effect. This states that when a fluid is forced through a narrow space, its velocity increases and its pressure decreases. This creates a vacuum, which can be used to remove gases or create a low-pressure environment.
The efficiency of steam ejectors depends on several factors, such as the design of the ejector, the operating conditions, and the type of fluid being removed. Generally, steam ejectors are very efficient and can achieve vacuum levels of up to 0.01 torr.
Steam ejectors are commonly used in industries such as chemical processing, oil and gas, food and beverage, and pharmaceuticals. They are used to create vacuums for various processes, such as distillation, drying, and degassing.
Steam ejectors have several advantages over other vacuum pumps. They have no moving parts, making them more reliable and requiring less maintenance. They also have a simple design and can handle corrosive or dirty fluids. Additionally, they can achieve higher vacuum levels and are more energy-efficient than other pumps.
