What is the difference between ejector and injector?

What is the difference between ejector and injector?

Ejectors are used for mixing liquid and solid products with a liquid (often water or steam). Injectors are used to increase the temperature of a liquid. It also causes a constant recirculation of the product inside the tank which ensures a good mixture and uniformity of temperature.

What is ejector condenser?

In the steam ejector system, the steam (auxiliary steam) is passed through a nozzle and allowed to expand in one chamber. When the HP steam passes through a nozzle it expands in the chamber and creates vacuum in the chamber; this chamber is connected to the condenser so that the condenser vacuum is created.

What is the purpose of ejector in steam turbine?

The main function of the ejector is to maintain the vacuum value in the condensation system of the turbine. According to this, main indicators of the efficiency, which influence the vacuum value in the condenser (pressure of the I stage and the length of the performance curve) are also connected with the reliability.

What is the difference between eductor and ejector?

1. The eductors are used to remove the air 4 times the volume of the vessel per hour for the vessel entry jobs. whereas the ejectors just suck the excess volume of the system and maintains the system pressure accurately. The difference is with respect to their function and not with respect with their motive fluid.

Where is ejector used?

The ejector is widely used as a vacuum pump where it is staged when required to achieve deeper vacuum levels. If the motive fluid pressure is sufficiently high, the ejector can compress gas to a slightly positive pressure. Ejectors are used both as subsonic and supersonic devices.

What is the ejector?

Ejectors are simple, static devices that use the energy within a high-pressure motive fluid (Gas or Liquid) to entrain and compress a low-pressure suction fluid (Flare Gas) to an intermediate discharge pressure.

Why ejector is used?

What is the purpose of ejector?

The purpose of the ejector is to transport and compress a weight of induced fluid from the suction pressure to the exit pressure. By staging ejectors it is possible to obtain a very large range of suction pressures from atmospheric down to as low as one micron of mercury absolute.

How does an ejector work?

An Ejector works by accelerating a high pressure stream (the ‘motive’) through a nozzle, converting the pressure energy into velocity. The two fluid streams then travel through the diffuser section of the Ejector, where velocity is decreased as a result of the diverging geometry and pressure is regained.

What is an eductor used for?

A water eductor or water dredge is an eductor-jet pump-based tool used by underwater archaeologists to remove sediments from an underwater archaeological site. Airlifts may be used for the same purpose.

What is the main function of ejector?

What are ejectors used for?

What is the difference between main ejector and start ejector?

The only difference is the utilization of used steam in case of main ejectors. In main ejectors the used steam is condensed and connected to a flash tank or the condenser, while in starting or hogging ejectors the used steam is let out to atmosphere.

What is an ejector condenser and how does it work?

Ejector condensers improve system efficiency by condensing the ejector motive steam and a portion of the saturation vapors to reduce the compression load on the flowing stages in the gas removal system. As for the ejectors, ejector condensers at geothermal steam plants are typically fabricated from Type 316L stainless steel.

What are the different types of ejector condensers at geothermal steam plants?

As for the ejectors, ejector condensers at geothermal steam plants are typically fabricated from Type 316L stainless steel. Ejector condensers are either direct contact or surface condensers typically in the same form as the main condenser. Shell and tube ejector condensers should be straight tube units, single or double pass with removable heads.

What is the difference between an ejector and a vacuum pump?

The major difference between the ejector and vacuum pump or compressor is it had no moving parts. Hence it is relatively low-cost and easy to operate and maintenance-free equipment.
