What Is A Desuperheater And How Does It Differ From An Attemporator?

1.	What Is A Desuperheater And How Does It Differ From An Attemporator?
Answer» A desuperheater is a DEVICE that is used to control the ADDITION of water to superheated steam to reduce the temperature to WITHIN 10°C of saturation. An attemporator also ADDS water to steam to control its temperature but the set point temperature is HIGHER and the downstream steam is still superheated. Generally desuperheaters are used in process plants where the steam is used for heating. Attemporators are used more in power stations for interstage temperature control.
