Abstract

Ceramic heat exchanger for use at temp. up to 1400 degrees C (e.g. in gas turbines) consisting of crosswise stacked plates provided with parallel, multiple ducts for the liquid or gaseous heat-exchange media is improved in that it is assembled by the module method. Elementary plates are produced by extrusion using different ceramic compsns.; then dried and opt. fired. The plates are then stacked in such a manner that the ducts in each plate are positioned at the right angle with respect to the ducts in the adjacent plates. The plates can be then sintered together. The cold and hot media flow crosswise through the alternating rows of ducts. Effective heat exchange is ensured because materials having high thermal conductivity can be used and the wall thickness is small (0.2-5 mm). Materials having good corrosion resistance at high temps. can be combined with gas-impermeable ceramics or metal foils. The assembly is resistant to temp. shocks.
