A vessel includes an outer wall and an inner wall arranged at a distance therefrom within the vessel and leaving an annular space relative to the outer wall. The inner wall is supported on the outer wall so as to allow for relative movements. In order to provide a vessel with which the danger of oscillations of the inner wall is avoided, with which a simple supply of medium is possible, which is easy to clean and with which the danger of an implosion of the inner wall is reduced, the inner wall is comprised of individual annular sections subsequently arranged in an axial direction of the vessel. Each section is supported on the outer wall independently of the other sections. An expansion joint is provided between two neighboring annular sections each.

1. In a vessel, such as a pressure vessel to be used in hydration or cracking plants, of the type including an outer wall, an inner wall arranged at a distance from said outer wall within said vessel and leaving an annular space relative to said outer wall, said inner wall being supported on said outer wall so as to allow for relative movements, the improvement of the inner wall comprising individual annular sections sequentially arranged in an axial direction of said vessel, means for supporting each of said annular sections on said outer wall, independently of the remaining ones of said annular sections, and an expansion joint bridging neighboring annular sections. 2. The vessel as set forth in claim 1, wherein said outer wall is provided with a lining. 3. The vessel as set forth in claim 1, wherein said outer wall includes a cylindrical part, said inner wall within said cylindrical part comprising neighboring cylindrical courses constituting said annular sections and at least three guides provided for each cylindrical course and radially extending from the axis of said vessel and adapted to movably support each of said cylindrical courses on said outer wall. 4. The vessel as set forth in claim 3, wherein said outer wall includes a bottom part and said inner wall in said bottom part comprises frustoconical or spherical-segment-shaped courses, each of said frustoconical or spherical-segment-shaped courses having a larger-diameter end directed toward said cylindrical courses and a smaller-diameter end directed toward said bottom part. 5. The vessel as set forth in claim 4, wherein said vessel further comprises supports extending in the direction of the vessel axis and adapted to support a frustoconical or spherical-segment-shaped course on said bottom part. 6. The vessel as set forth in claim 5, wherein said frustoconical or spherical-segment-shaped course is supported at about half its height, measured from said smaller-diameter end. 7. The vessel as set forth in claim 5, wherein said frustoconical or spherical-segment-shaped course is supported above half its height, measured from said smaller-diameter end. 8. The vessel as set forth in claim 3, wherein said cylindrical courses comprise parts neighboring in the peripheral direction and being connected by seams extending parallel with the axial direction of said vessel. 9. The vessel as set forth in claim 3, wherein said guides are formed by pipings penetrating said outer wall, and which further comprises pipe sockets mounted to said courses so as to penetrate said courses and projecting into said piping with play. 10. The vessel as set forth in claim 3, wherein said guides are formed by pipings penetrating said outer wall, and which further comprises pipe sockets mounted to said courses so as to penetrate said courses, said pipings projecting into said pipe sockets with play. 11. The vessel as set forth in claim 3, wherein said vessel includes a medium-draining bottom and each of said courses, on its end positioned toward said medium-draining bottom, being provided with a radially inwardly offset step ring extending into the neighboring course in the direction of the axis of said vessel. 12. The vessel as set forth in claim 3, wherein said expansion joints include flexible sieve rings bridging said neighboring courses. 13. The vessel as set forth in claim 4, further comprising course-surrounding supports fastened to said outer wall so as to project towards said courses and surrounding said courses with radial play. 14. The vessel of claim 1, wherein said annular sections are axially apart from each other. 15. A vessel, such as a pressure vessel to be used in hydration of cracking plants, said vessel having a cylindrical part including an outer wall, an inner wall arranged at a distance from said outer wall within said vessel and leaving an annular space relative to said outer wall, said inner wall comprising coaxially aligned, individual cylindrical courses, an annular expansion joint sealingly extending between adjacent cylindrical courses, and means for supporting each cylindrical course on said outer wall independently of the other annular sections, so to permit independent radial and axial expansion of each cylindrical course, said means for supporting each cylindrical course comprising a plurality of guide members extending radially outward from said cylindrical course and sleeve members secured to said outer wall, said sleeve members being sized and positioned relative to said guide members so as to receive said guide members with radial and axial play. 16. The vessel of claim 15, wherein said cylindrical courses are axially apart from each other.
