Jet Condenser- Definition, Types, Application and Advantages

Engineers Rail welcomes you. If you want to learn further about Jet Condenser?

You’ve got to the correct place. The definition, type, benefits, drawbacks, and application of a Jet condenser can all be found here.

So, without further ado, let’s get this party started. But, Let’s start with the fundamentals first-

What is Condenser?

A condenser is a heat-exchanging device that converts gaseous or vapour state compounds to liquid states.

Working Principle of Condenser-

Heat Transfer will be how the condenser works.

The primary idea behind the condenser’s operation is heat transfer, which is accomplished by the use of cooling agents in the chamber.

What is Jet Condenser?

A jet condenser is a type of condenser that combines steam and cooling water in a chamber where the steam is transformed into liquid form. The jet condenser is also known as a Mixing type condenser.

Types of Jet Condenser-

Jet condensers are divided into three categories:-

  1. Low-level Jet Condenser
  2. High-level Jet Condenser or Barometric Jet Condenser 
  3. Ejector Condenser

Low-Level Jet Condenser- 

The low-level jet condenser is classified into two categories-

  • Parallel Flow Jet Condenser
  • Counterflow Jet Condenser

Parallel Flow Jet Condenser-

A parallel flow jet condenser gets its name from the fact that steam and water come from the top of the condenser and flow parallel to each other. This is because the air pump creates a vacuum, which allows water and steam to flow.

The heat from the steam is transferred to the running water during the passage of water and steam, as heat always moves from higher to lower temperatures.

The condensate gathered at the bottom of the condenser is collected. To speed up the process, perforated trays and an air pump are utilised. The condensate is transferred to the hot well via an extraction pump placed at the bottom.

Condensate is supplied to the boiler after passing via the hot well. When compared to other types of jet condensers, the design of a parallel flow jet condenser is fairly straightforward.

Counter Flow Jet Condenser-

Steam and water flow in opposite directions. Steam enters the chamber from below while cooling water enters from above in a counter-flow jet condenser. A vacuum is created by the air pump, which forces cooled water into the condenser.

Through perforated trays, heavy water drips down and light steam rises up. The perforated trays collect the falling water. When cooling water collides with steam on its way to the bottom, a heat transfer process occurs, resulting in condensate accumulation.

With the help of a pump, the condensate is pumped into the hot well. The hot well is drained of its condensate. The equipment needed to build a counterflow jet condenser is less expensive and uncomplicated. A smaller amount of cooling water is required.

High-level Jet Condenser or Barometric Jet Condenser-

The barometric or high-level jet condenser is similar to the counter flow jet condenser in operation. A long discharge pipe from which the condensate passes and gathers in the hot well is one of the few adjustments to the fundamental structure.

The air pump and injection pump force cooling water from the top of the condenser and steam from below; again, steam rises and waterfalls through perforated trays because steam is lighter than water. Heat transfer between water and steam occurs, resulting in condensate that settles.

There is no requirement for a pump to extract the condensate, unlike other condensers. Because of the long discharge pipe, the potential energy of the condensate is large enough to cause it to drop.

Ejector Condenser-

Steam and cooling water mix in an Ejector type jet condenser and flow through a series of metal cones. These metal cones lengthen the time it takes for the water to fall, lengthening the time it takes for heat to be transferred.

A non-return valve allows steam to enter but not leave the condenser. While flowing through the cone, where the heat transfer process occurs, steam and cooling water are correctly combined. Pumps are not required because the cross-sectional area does not narrow. In a hot well, the condensate is collected.

Applications of Jet Condenser-

Some of the Jet Condenser’s Applications include:

  • Evaporators to condense gases
  • Vapour pans to condense vapours
  • Used to condense steam or hot air

Advantages of Jet Condenser-

The advantages of a Jet Condenser are as follows:

  • Easy Method
  • Economical
  • Simple Design
  • Less amount of coolant is used
  • Small in size
  • Less maintenance cost

Disadvantages of Jet Condensers-

Jet condensers have the following drawbacks:

  • Restriction in using condensate water
  • High power requirement
  • Low vacuum efficiency
  • Low overall efficiency
  • Low capacity
