METHOD AND SYSTEM FOR SEALING AN ANNULUS

A purged seal system for an annular space (212) that includes an inner surface (210) of a radially outer vessel, an outer surface (208) of a radially inner vessel, and a seal passage therebetween, the annular space is divided into an upper annular space (214) and a lower annular space (216) by the p...

Beschreibung
Zusammenfassung:	A purged seal system for an annular space (212) that includes an inner surface (210) of a radially outer vessel, an outer surface (208) of a radially inner vessel, and a seal passage therebetween, the annular space is divided into an upper annular space (214) and a lower annular space (216) by the purged seal is provided. The system includes a first baffle element (218) that extends from the inner surface into the seal passage at an oblique angle with respect to the inner surface, a second baffle element (222) that extends from the outer surface above the first baffle element in a direction opposite gravity flow into the seal passage, the second baffle element extends at an oblique angle with respect to the outer surface, and a third baffle element (228) that extends from the inner surface above the first baffle element in a direction opposite gravity flow into the seal passage, the third baffle element extends at an oblique angle with respect to the inner surface, a distal end of the third baffle element is positioned proximate a distal end of the second baffle element.
