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. 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.
