US 2014/0326353 A1 · EXPANSION JOINT IN A VERTICAL CHANNEL

Abstract

An expansion joint in a vertical channel suitable for conducting hot particles. The expansion joint includes an upper channel portion including a lower end portion with a lower edge. A lower channel portion is sealingly connected by a flexible element connected on an outer side of the vertical channel. The lower channel portion includes an upper end portion with a horizontally extending upper plane. In a predetermined vertical level range, the upper end portion telescopically overlaps the lower end portion in a spaced relationship, to permit relative axial and lateral movements of the upper channel portion and the lower channel portion, whereby the upper plane is at a higher level than the lower edge. A sealing ring, including mutually connected sealing blocks positioned on an outer circumference of the lower end portion, is arranged on the upper plane.

A method of forming an expansion joint in a vertical channel suitable for conducting hot particles, the expansion joint comprising (i) an upper channel portion, the upper channel portion comprising a lower end portion with a lower edge, and (ii) a lower channel portion, the lower channel portion comprising an upper end portion with a horizontally extending upper plane, the method comprising the steps of:

(a) arranging the upper channel portion and the lower channel portion so that, in a predetermined vertical level range, the upper end portion telescopically overlaps the lower end portion in a spaced relationship, to permit relative axial and lateral movements of the upper channel portion and the lower channel portion, whereby the upper plane is at a higher level than the lower edge;
(b) arranging on the horizontally extending upper plane a sealing ring comprising mutually connected sealing blocks positioned on an outer circumference of the lower end portion;
and
(c) thereafter, sealingly connecting the upper channel portion and the lower channel portion by connecting a flexible element on the outer side of the vertical channel.
