Claims
- 1. A heat exchanger adapted for the production of carbon black and comprising:
a substantially cylindrical, closed vessel defining a space; a horizontal support wall disposed within the space adjacent an upper portion thereof; a plurality of tubes affixed to the support wall and hanging downwardly therefrom, a tube plate situated adjacent a lower portion of the space, the tube plate including upper and lower walls spaced vertically apart to form a manifold therebetween; and a plurality of metallic bellows disposed around respective tubes, each bellows extending between the respective tube and the tube plate, the bellows being compressible and expandible to accommodate thermal expansion and contraction of the tubes.
- 2. The heat exchanger according to claim 1 wherein a protective sleeve surrounds a lower part of each tube, and an outer sleeve is arranged coaxially around the protective sleeve, the bellows disposed in a chamber formed radially between the protective sleeve and the other sleeve.
- 3. The heat exchanger according to claim 1 wherein the bellows creates a gas-tight seal at upper and lower ends of the chamber.
- 4. A tube plate adapted for use in a heat exchanger, comprising:
an upper wall and a lower wall forming a manifold therebetween; upright heat exchanger tubes extending through the manifold; and a plurality of metallic bellows disposed around respective tubes, each bellows being thermally compressible and contractible, to accommodate thermal expansion and contraction of the respective tube.
- 5. The tube plate according to claim 4 further including a protective sleeve surrounding a lower part of each tube, an outer sleeve situated radially outside of each protective sleeve to form a chamber therebetween, each bellows disposed in a respective chamber.
