Abstract
The present invention relates to an apparatus and method of deploying a desuperheater with a Seat-Ring designed to provide coolant injection at high temperature differential. The present invention's robust design provides for a high level of flexibility that allows operating at high temperature differentials between the coolant and the superheated fluid. The desuperheater Seat-Ring is made as a split hollow ring with a perpendicular slit traversing the ring's circumference. The opened slit design provides a high level of flexibility, which allows the seat ring to sustain severe temperature extremes by reducing thermal stress. The coolant is supplied to the seat ring through a specially designed coolant nipple liner connected to the seat-ring.
