How does a jet condenser work?
A condenser works on the principle of heat transfer (heat energy always flows from higher temperature to lower temperature). It transfers heat from hot steam from the compressor to the coolants and converts it into water.
Which type of the condenser are of jet types?
There are mainly three types of jet condensers.
- Low level condenser.
- High level condenser.
- Ejector condenser.
What is an 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.
Which nozzle is used in ejector condenser?
The injection water in rushing into the condenser through the conoidal nozzle, attains a velocity proportional to the vacuum, and this velocity, which the jet of water retains, is found sufficient to enable it to discharge itself through the induction tube C, which is so formed, that its area increases inversely with …
Where is jet condenser used?
An illustration showing the application of a jet condenser to pump a well. The steam enters the engine and leaves as exhaust. The exhaust steam is cooled by the well water in the jet condenser, then gets pumped into a separator.
What are the advantage and disadvantages of jet condenser?
Advantages and disadvantages of jet condensers: Simple equipment and cost are low. Less space is required. The cooling water pump is not needed in the low-level jet condenser. Condensate extraction pump is not needed for high level and ejector condensers.
How jet condenser is different from surface condenser?
Surface condensers (or non-mixing type condensers). In surface condensers, there is no direct contact between the exhaust steam and the cooling water. In jet condensers, there is direct contact between the exhaust steam and cooling water.
What is a barometric condenser?
[bar·ə′met·rik kən′den·sər] (mechanical engineering) A contact condenser that uses a long, vertical pipe into which the condensate and cooling liquid flow to accomplish their removal by the pressure created at the lower end of the pipe.
Why steam is used in ejector?
Steam ejectors use steam or gas instead of moving parts to compress a gas. In a jet or ejector, a relatively high-pressure gas, like steam or air, expands through a nozzle. The steam or air converts that pressure or potential energy to velocity or kinetic energy.
How vacuum is created in ejector?
In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area. The fluid leaving the jet is flowing at a high velocity which due to Bernoulli’s principle results in it having low pressure, thus generating a vacuum.
What is the difference between jet condenser and surface condenser?
1 Types of Surface Condensers: 1.2. 1.1 Down flow condenser. 1.2….Difference between surface condenser and jet condenser.
| S.NO | Surface Condenser | Jet or Direct Contact Condenser |
|---|---|---|
| 3 | Condensate is reused. | Condensate is wasted |
| 4 | It requires large quantity of circulating water. | It requires less quantity of circulating water |
How does an ejector type jet condenser work?
In the Ejector type jet condenser the steam and cooling water mixes together and pass through few metal cones. These metal cones increase the time taken by the water to come down, thus increasing the time of heat transfer. The steam enters into the condenser through a non-return valve (the steam can only go in and can’t come out of the valve).
How many types of jet condensers are there?
There are mainly three types of jet condensers. Low level condenser. High level condenser. Ejector condenser.
Do jet condensers need a pump?
Unlike other condensers, there’s no need for a pump to extract the condensate. The potential energy of condensate is high enough to make it fall this is because of the long discharge pipe. In the Ejector type jet condenser the steam and cooling water mixes together and pass through few metal cones.
How does a counter flow jet condenser work?
The exhaust steam enters from the side near to the bottom of the condenser. This is basically a counter flow jet condenser. Here, the steams travels upwards inside the condenser whereas the water jets falls from top. The condensates and cooling water comes to the hot-well through vertical tail pipe due to gravitational force.
