Desuperheaters are crucial components that are used in the thermal management of heat. This heat is generated from power generation sources to the industrial uses such as refrigeration and air conditioning.
The gas becomes more efficient when it gets saturated, especially when it is used for heating or other heat transfer or even in the industrial processes.
A desuperheater is mainly a device that helps to lower the temperature of superheated gas in order to use the gas efficiently. This gas is used for heating or for any other industrial use.
There are several types of desuperheaters that include the Venturi desuperheater and the annular Venturi desuperheater that bring steam directly into contact with water to reduce steam temperature. These types are useful where there is a lack of atomizing steam.
On the other hand, an attemperator desuperheater is one of the low cost solutions used when lesser flow variation is needed and a low pressure drop is needed.
One of the other major types include surface absorption desuperheaters that forces desuperheated steam to create a contact with wetted metal reaction rings.
When the temperature of the superheated gas is lowered, the gas can be used effectively. This minimization is called as attemperation. It is one of the functions performed by the desuperheater.
Steam desuperheaters are placed well before the condenser and the oil separator. There is the ammonia refrigerant that travels through the different tubes before it enters the condenser.
Desuperheater is mainly manufactured considering the requirements of hot water for industrial processes.
When there are no needs of refrigeration simultaneously, the hot water is generated, stored and is maintained in a separate insulated tank. The stored hot water can be later utilized as and when required for future use.
