What is a jet condenser?
Jet condenser is a condenser in which the condensate gets mixed with the cooling water. That’s why it is also called as mixing type condenser. This type of condenser is used sometime because it lost some of the condensate and requires high power for the pump during the process of condensation.
How many types of jet condensers are there?
There are mainly three types of jet condensers. Low level condenser. High level condenser. Ejector condenser.
What are the advantages and disadvantages of jet condenser over surface condenser?
Difference between surface condenser and jet condenser
| S.NO | Surface Condenser | Jet or Direct Contact Condenser |
|---|---|---|
| 6 | Its maintenance cost is high. | Its maintenance cost is low. |
| 7 | Less power is required for air pump. | More power is required for air pump. |
| 8 | Less power is required for waste pumping | High power is required for water pumping |
What are the advantage and disadvantages of jet condenser?
Advantages and disadvantages of jet condenser
The construction is simple. Installation and maintenance cost is low. It requires less floor space when compared to the surface condenser. The mixing of vapour and condensing medium reduces the amount condensing medium required.
Where is jet condenser used?
A jet condenser is a direct type of condenser hence used for condensing vapors in evaporators. It is also used for condensing vapors in a vapor pans. Jet condensers are used in some of the thermal power plants to condense steam or hot air.
What is difference between surface condenser and jet condenser?
In surface condensers, there is no direct contact between the exhaust steam and the cooling water. Jet condensers (or mixing type condensers). In jet condensers, there is direct contact between the exhaust steam and cooling water.
What is difference between jet condenser and surface condenser?
What is high level jet condenser?
Barometric or High-Level Jet Condenser
Exhaust steam enters to the lower side of the condenser and direction of steam flow is upward direction. Cooling water also enters from upwards of the shell and stored at perforated conical plate. Vacuum is created by air pump, placed at the top of the condenser shell.
What are the advantages of surface condenser over jet condenser?
Advantages of surface condenser over jet condenser
- There is a high vacuum obtained compared to the jet.
- Water used for cooling is reused without any treatment.
- For high capacity plants, it is More advantageous.
- In this Condensate losses can be eliminated.
- It required power for air pump is low.
Why it is called surface condenser?
It is called the surface condenser because the exhausted steam and cooling water does not mix up.
What is the difference between jet condenser and surface condenser?
What are the 4 types of condenser?
Air-cooled Condenser
- 1.1. Natural Convection. In this type of condenser, air comes to contact with warm coils, absorbing the heat of refrigerant inside the coils, consequently the temperature of air increases.
- 1.2. Forced Convection.
- 2.1. Double Tube.
- 2.2. Shell and Coil Condensers.
- 2.3. Shell and Tube Condensers.
Where is a jet condenser used?
What is the purpose of a surface condenser?
The function of a surface condenser is to create the lowest possible turbine or process operating back pressure while condensing steam. The condensate generated is usually recirculated back into the boiler and reused.
What are the 3 major types of condensers?
Three main types are separated into: Air-cooled condensers. Water-cooled condensers. Combined air and water-cooled condensers.
What type of condenser is the most efficient?
Water-cooled systems are more efficient for heat transfer than air-cooled systems because air-cooled systems are limited by the dry bulb temperature, resulting in higher condensing temperatures and therefore lower chiller efficiency.
