| 摘要 | The invention relates to refractory members for use in the construction, by stacking of a number of such members, thermal regenerators or recuperators, such as those used in conjunction with glass or metallurgical furnaces, for recovering the heat contained in flue gases. The invention provides that the refractory member is formed of a monolithic structure cast from fused refractory oxides. The member is in plan aspect shape composed predominantly of elongated portions, each having over the greater part of its length a maximum width which does not exceed 50 mm. The overall dimensions of the refractory member are sufficient to afford stability in stacking. The member may be star-shaped in plan aspect and it is advantageously formed by a number of parallelepipedal members joined together by casting into a monolith. | ||||||
| 权利要求 | 1. A stackable refractory member useful for constructing thermal regenerators or recuperators, said member being constructed of fused, cast refractory oxides and comprising: an elongated hub portion having a major longitudinal axis extending centrally thereof in the direction of said elongation thereof; and at least three identical arm portions which are integral with said hub portion and which extend radially outwardly from said axis, the dimension of each of said arm portions in a direction parallel to said axis being substantially coextensive with the length of the hub portion along said axis, the width of each of said arm portions in a direction perpendicular to both said radial extension thereof and said dimension thereof being 50 mm or less, said arm portions being angularly distributed about said axis. 2. A refractory member as set forth in claim 1 wherein said arm portions are angularly spaced about said axis in substantially equidistant relative relationship. 3. A refractory member as set forth in claim 1 wherein said arm portions are generally parallelepipedal in shape. 4. A refractory member as set forth in claim 2 wherein are included three arm portions spaced 120* apart about said axis. 5. A refractory member as set forth in claim 2 wherein are included four arm portions spaced 90* apart about said axis. |
