Desuperheaters are basically used to cool steam in power plants. Desuperheating is the process of regenerating superheated steam to its saturated state with the help of temperature reduction. There are two basic types of desuperheaters that is indirect contact and direct contact.

3. Introduction
A direct contact steam desuperheater transfers moisture through
small holes into the path of high-velocity steam.
After the transformation, the water is atomized into small drops and
quickly evaporated by absorbing the superheat.
The amount of the steam temperature downstream is used to control
the amount of water added during desuperheating.

4. Desuperheaters are basically used to cool steam in power plants.
Desuperheating is the process of regenerating superheated steam to
its saturated state with the help of temperature reduction.
There are two basic types of desuperheaters that is indirect contact
and direct contact. Indirect contact includes desuperheaters such as
shell and tube heat exchangers separate the steam and the medium
used to cool it.
Direct contact steam includes desuperheaters do not.

5. What is Desuperheater
A device that cools down the superheated refrigerant (gas that's at a
temperature on top of its saturation temperature) is nothing however
a desuperheater.
The temperature of this gas is reduced by spraying droplets of water
into the flow of the superheated gas.

6. Types of Desuperheater
1) Freon: Maniks desuperheater works on Freon refrigerant gas to
extract the superheated refrigerant and use it for other purposes.
Therefore this heat if used for boiling water in hotels, restaurants etc
users can get free of cost water.
2) Ammonia: Ammonia is the oldest one of all the refrigerants and it
is still widely used in the refrigeration and air conditioning
applications.
It is additionally the sole refrigerant outside the halocarbons cluster,
still being used to a great extent.

7. Desuperheater Fundamentals
In a usual AC & R system, the refrigerant temperature rises in tune
of 80 to 120 after compression.℃ ℃
The refrigerant is more place to the air/ water cooled condenser to
condense close to concerning 40 .℃
While the compression of refrigerant within the condenser, the total
heat contained in this high Temperature/high pressure gas gets
wasted to the atmosphere.
This superheat of the gas that is an element of the entire enthalpy of
the gas, has a substantial heat potential provided the same is
reclaimed efficiently and is optimized

8. Installation
The Maniks Desuperheater storage tank is placed before the
condenser and also the oil centrifuge.
The ammonia refrigerant travels through the different tubes in the to
lower the refrigerant temperature before entering the condenser.
The Water heater is manufactured considering the hot water
requirements for industrial processes.

9. Design
Double walled “Tube in Tube “, vented, counter flow heat
exchanger.
Vent tube having serrations on inner & outer surfaces to avoid cross
contamination of refrigerant and water/ fluid.
Each tube incorporates a tube within that permits water/ fluid to
travel in associate degree other way.
