Abstract
Disclosed is a high temperature heat recovery system having a unique high temperature heat exchanger made of refractory and ceramic materials which can operate in gas streams of up to about 1,500.degree. C.
Claims28
A ceramic heat exchanger for a heat recovery system comprising:
- a shell having a first tube sheet at a first end and a second tube sheet at a second end;
- at least one ceramic heat exchanger tube disposed between said first tube sheet and said second tube sheet, said ceramic heat exchanger tube mounted into seal assembly means on each of said tube sheets;
- and
- each of said seal assembly means allowing for both axial tube expansion and contraction as well as angular freedom of motion to prevent the development of a moment force on said ceramic heat exchanger tube.

A ceramic heat exchanger for a heat recovery system, comprising:
- a shell having a first tube sheet at a first end and a second tube sheet at a second end;
- at least one ceramic heat exchanger tube disposed between said first tube sheet and said second tube sheet, said ceramic heat exchanger tube mounted into seal assemblies on said tube sheets;
- and
- each of said seal assemblies comprising a ball seal mounted in said tube sheets, said ball seal for allowing tube expansion and contraction without displacing said tube sheets, said ball seal having a radius of curvature centered from the centerline of said ceramic heat exchanger tube in two planes which allows an angular freedom of motion for said ceramic heat exchanger tube.

A ceramic heat exchanger for a heat recovery system, comprising:
- a shell having a refractory lining, said shell having a first tube sheet assembly at a first end and a second tube sheet assembly at a substantially opposing end;
- each said tube sheet assemblies comprising a hot side plate and a process side plate, said hot side plate and said process side plate being substantially parallel to each other and having therebetween a hollow spacing means;
- at least one ceramic heat exchanger tube mounted between said first tube sheet assembly and said second tube sheet assembly, each said ceramic heat exchanger tube having a centerline, said hollow spacing means between said parallel plates of said tube sheets being concentric to said centerline;
- and
- at least two ball seals holding said at least one ceramic heat exchanger tube in said tube sheet assemblies, each said ball seal having a radius of curvature centered from said centerline of each said ceramic heat exchanger tube in two planes which allows an angular freedom of motion for said ceramic heat exchanger tube.
