What are advantages of condenser?
Advantages of a condenser in a steam power plant It reduces back pressure of the steam which results in more work output. It reduces temperature of the exhaust steam which also results in more work output. The condensed steam can be reused as feed water for boiler which reduces the cost of power generation.
What are the advantages and disadvantages over jet condenser?
Advantages and disadvantages of surface condenser Since there is no mixing, cooling medium (water) of poor quality can be used. This advantage reduces the cost of water treatment. Cooling of condensate can be easily controlled by regulating the flow of cooling medium. Suitable for large plants.
What is the main advantage of condenser splitting?
This method is referred to as condenser splitting . Its main advantage is to keep a reasonable head pressure in colder ambient while not having to hold excessive amounts of refrigerant charge in a flooded condenser.
What is the main disadvantage of contact condensers?
Space requirements are significantly less for spray condensers than required for surface condensers. The main disadvantage of direct-contact condensers is that the steam condensate is mixed with the cooling water.
What are some possible disadvantages with water cooled condensers?
Disadvantages of water-cooled condensers:
- Installation cost is more.
- It required more maintenance.
- Operating the water-cooled condenser is not easy.
- It is not so flexible to use everywhere.
- It required an additional recirculation system for used water.
- Water cooled condenser parts undergo to corrosion effect.
What are the advantage and dis advantage of surface condenser over jet 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 advantages of a jet condenser?
Advantages of Jet Condenser: Less amount of water or coolant is required in jet condensers. Jet condensers are quite small in size therefore they acquire less area. The maintenance cost of jet condensers is quite low. Unlike other condensers, the cooling water and steam mix together physically in jet condensers.
What advantages can a jet condenser claim over a surface condenser?
Jet Condensers
- Contact between steam and cooling water is direct.
- Condensate is not fit for reuse as boiler feed water since circulating water contains impurities.
- Vacuum rarely exceeds 650 mm of mercury.
- Quantity of cooling water is less.
- Less maintenance cost.
- Low manufacturing cost.
- Requires less floor area.
How is condenser temperature difference?
In air-cooled condensers, the temperature difference between the ambient and the condensing temperature is referred to as the condenser split. For example, if the condensing temperature is 110 degrees F and the ambient is 80 degrees, the condenser split would be 30 degrees.
Which of the following condensers is the most efficient?

| Which of the following condensers is the most efficient? | D. Water-cooled counterflow |
What are advantages and disadvantages of water cooling over air cooling?
Water-cooled chillers usually don’t need replacement as often as air-cooled chillers do. They aren’t exposed to outdoor elements such as rain, snow, ice, and heat, which makes them less vulnerable. While air-cooled chillers have ducts and vents that create noise, water-cooled chillers operate quietly.
What are the advantages of water-cooled condenser?
Advantages of a Water-Cooled Condenser A water-cooled system typically lasts years longer, assuming maintenance is not neglected. It has higher heat transfer rate. It consumes far less overall energy, which can lead to savings on energy costs and consumption. It does not require any external power.
