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.
