Desuperheaters are devices that lower the temperature of superheated gas or vapor by injecting water droplets into the flow. This brings the temperature down to the saturation level and prevents wasted heat. Desuperheaters have applications in power generation to stabilize temperatures for condensers, in process control, and to allow for thinner pipes and prevent lubricant degradation in machines. They provide effective heat transfer between gases and water to precisely control refrigerant temperatures for various industrial processes.

3. Introduction
A desuperheater could be a device that cools superheated gas to a
temperature about to its traditional temperature, generally by
spraying penalized droplets of water into the flow of supeheated
gas.
Superheated gas is gas that's at a temperature on top of its traditional
temperature.

4. The primary operate of a desuperheater is to lower the temperature
of superheated steam or alternative vapors.
This chilling is accomplished as a results of the method vapor being
brought into direct contact with another liquid like water.
The injected water is then evaporated.

5. Basic Theory
Superheated refrigerant is gas that's at a temperature that's above the
traditional temperature, at the superheated level.
This extra heat is wasted in atmosphere which:
• Is higher than saturation temperature.
• Contains more energy.
• contains a larger specific volume than saturated gas.

6. The overall purpose of a desuperheater water heater is to provide
effective heat transfer between refrigerant and water.
Desuperheaters heater comes in a very kind of configurations
together with probe vogue with variable or fastenednozzle, double
venture and venturi. With a style that has finely controlled water
spray that ends up in reducing refrigerant temperature at saturation
level.

7. Applications
1.Power generation
Boilers running at minimum hundreds or with high power, produce
variable temperature gas.
Desuperheaters are wont to stabilize superheat over wide selection
of flows.
Surface condensers work most effectively once equipped saturated
gas.
This reduces the necessity to feature tubes for cooling the
superheated gas, and prevents burden caused by thermal growth
whenever the new, dry refrigerant gas enters the condenser.

8. 2.Process controllability
Desuperheaters additionally facilitate to regulate a range of
processes.
Maniks has a wide range of desuperheaters as they provide precise
refrigerant temperature control for various applications in boilers,
chemical, oil & gas process plants, etc where the available
refrigerant is at superheated conditions.

9. 3.Thinner pipe and lighter flanges
Cooler gases needs skinny pipe schedules or lighter rim than
superheated gas.
Besides from lower prices, this can reduce down- times for piping,
controls, valves and other equipments during their initial
constructions or shutdown maintenance.

10. 4.Preventing lubricant degradation
Superheated gas could straightaway degrade bound lubricants,
therefore the saturated gas is employed for dearspecial things like
compressors and pumps.
