专利汇可以提供Heat regenerator专利检索，专利查询，专利分析的服务。并且A heat regenerator of the type comprising, within a wall of refractory material, a space containing a pile of bricks (checker brick) and a burner stack separated therefrom by a separating wall, the cylindrical wall of the heat regenerator and the separating wall consisting of more than one layer of refractory material, in which at least for part of the walls and in particular for the separating wall between checker bricks and burner stack, at least one of the layers of refractory material is subdivided by a vertically extending expansion joint to avoid cracks, damage and gas leaks through the concerning wall or walls. Preferably there is a number of such joints in the separating wall, extending at least over the height of the lower half of the burner stack. The facing edges of the layer at the joint have grooves with sealing bricks engaging therein or tongues and grooves engaging sealingly, with a compressible filler of ceramic wool or felt sealing the joint in cold condition of the regenerator.，下面是Heat regenerator专利的具体信息内容。

权利要求

1. In a heat regenerator assembly comprising a cylindrical wall member of refractory brick and a separating vertical wall section of refractory brick positioned interiorly thereIn thereby forming within said cylindrical wall member a separate zone for receiving a pile of refractory and heat accumulating bricks and a separate burner stack zone, the improvement comprising having said vertical wall section made up of at least two side by side vertically extending wall portions of refractory material with each said wall portion comprising layers of refractory material elements in substantially face to face relation and with at least one of the layers of at least one of the wall portions of the vertical wall member for at least part of the length thereof having vertically extending, horizontally expansible expansion joint means between the abutting ends of said refractory material elements making up the layers of the wall portions to permit circumferential expansion thereof.

2. A heat regenerator in accordance with claim 1, wherein each of the several layers of refractory material of the wall portions forming the separating wall have such vertically extending expansion joints for at least over the height of the lower half of the burner stack, said expansion joints being formed by mutually engaging profiled shapes extending for the entire height of the joints.

3. A heat regenerator according to claim 2, wherein the expansion joints in said layers of the wall partitions forming the separating wall are staggered mutually.

4. A heat regenerator in accordance with claim 1, wherein said expansion joints each include cooperating protruding and recessed portions each forming a tongue and groove assembly, the portions of said joints which are in spaced relation when in the cold state being filled at least in part with a compressible refractory filler material.

5. A heat regenerator in accordance with claim 4, wherein the tongue and groove assembly has a trapezoidal configuration.

6. A heat regenerator according to claim 4, the tongue and groove assembly having a rectangular configuration.

7. A heat regenerator according to claim 1, wherein the expansion joints in the layers of the wall portions are formed by recesses in the abutting ends of the refractory material making up the layers of the wall portions, the hollow space thus formed being filled by refractory elements slidable therein.

8. A heat regenerator according to claim 1, wherein the expansion permitted by the joints is larger than the thermal expansion of the layers in a horizontal direction transverse to the joints, at about the highest operating temperature which may occur in the same region.

9. A heat regenerator according to claim 1, wherein the joints extend over substantially the entire height of each of the layers of the wall portion in which they are provided.
