Abstract
The present invention relates generally to furnace systems and more particularly, but not by way of limitation, to a split-ring assembly for sealing a junction between a catalyst tube and a furnace. In one aspect, the present invention relates to a ring-seal assembly. The ring-seal assembly includes a housing ring coupled to an outer surface of a furnace. The housing ring is disposed around a circumference of a tube proximate a junction with the furnace. The ring seal assembly further includes a brush seal that is at least partially disposed within the housing ring. The brush seal is disposed around the circumference of the tube. A plurality of brushes extend radially inwardly from the brush seal towards the tube.
Claims11
A ring-seal assembly comprising:
- a housing ring coupled to an outer surface of a furnace and disposed around a circumference of a catalyst tube proximate a junction with the furnace;
- a plurality of split brush-seal rings at least partially disposed within the housing ring, the plurality of split brush-seal rings disposed around the circumference of the catalyst tube, each brush-seal ring of the plurality of split brush-seal rings comprising a single joint, wherein a joint of a first split brush-seal ring of the plurality of split brush-seal rings is arranged in a circumferentially staggered orientation from a joint of an adjacent split brush-seal ring of the plurality of split brush-seal rings;
- and
- the plurality of split brush-seal rings comprising a plurality of brushes extending radially inwardly towards the catalyst tube.
A method of sealing a junction between a tube and a furnace, the method comprising:
- installing housing ring to an outer surface of a furnace and about a circumference of a catalyst tube proximate a junction with the furnace;
- installing a plurality of split brush-seal rings around the circumference of the catalyst tube and at least partially disposing the plurality of split brush seal rings within the housing ring, each brush seal ring of the plurality of split brush-seal rings comprising a single joint;
- arranging the plurality of split brush-seal rings such that a joint of a first split brush-seal ring of the plurality of split brush-seal rings is circumferentially staggered from a joint of an adjacent split brush-seal ring of the plurality of split brush-seal rings;
- and
- contacting a plurality of brushes extending radially inwardly from the plurality of brush-seal rings with an outer surface of the catalyst tube.
