Heat Regenerators: Direct-Contact Heat Storing Exchangers using a Batch of Solids

  • Octave Levenspiel
Part of the The Plenum Chemical Engineering Series book series (PCES)


Because solids, on a volume basis, have a very large heat capacity compared to gases, they can effectively be used as an intermediary in the transfer of heat from one gas to another. This requires a two-step operation. In the first step hot gas gives up its heat to cold solids. The solids heat up, and then in the second step the solids release this heat to a second cold gas. For continuous operations regenerators are used in pairs, as shown in Fig. 15.1.
