A Desuperheater are secondary heat exchanger devices with applications in power generation to various industrial processes like in air conditioning, refrigeration, food and textile processing, etc.

One common use of these devices is transferring heat from the earth in winters and homes in summer, into the hot water tank.

These crucial devices are utilized in various processes that are dependent on the thermal management of heat. Desuperheater is also used to bring down the temperature of a superheated gas to make it saturated.

The gas used in industrial processes or heat transfer is most efficient when it is saturated, and this can be achieved with a steam desuperheater.

General Purpose of a Desuperheater in Different Industries

These heat exchanger devices are an efficient means of controlling the temperature and pressure of steam. This enables production companies to achieve cost-reduction and the convenience in transferring steams through thinner pipes in lower grade alloys.

There are several other applications of this device besides reducing the temperature of gas.

It can be injected into various types of gases in order to produce different sorts of vapors. It’s one of the most extensive application is found in the LNG plant setting.

LNG desuperheaters are forever making energy plants more efficient and keeping plants functional at reduced costs. These devices are specifically designed for LNG terminals, and by direct injection, these ensure secure discharge of the LNG carrier.

Other Areas of its Uses

Desuperheaters being so crucial in various industrial processes can be seen functioning across a diverse range of industries.

• Hotels & Hospitals
• Textile
• Engineering and Automobile
• Dairy and Food Processing
• Pharmaceutical
• Chemical

The Principle Behind the Working of Desuperheaters

Essentially, a desuperheater device lowers the temperature of superheated gas and vapors. This process of temperature reduction can be achieved by bringing vapor in direct contact with a liquid like water. The injected water will then evaporate.

Benefits

• From 80 to 90 percent of cost reduction can be achieved with these devices.
• Surface condensers are more efficient specially when working with saturated steam. This process eliminates requirement for adding tubes for the purpose of cooling superheated steam and prevent thermal expansion when the dry and hot steam enters the condenser.

Steam desuperheater has a wide range of applications like in toluene, natural gas, methanol, R-134a, etc. It can also be designed for various mixtures of gases as per the requirements.
