Comparing 'Boiling Layer' and 'Dense Layer' Types of Heat Exchangers for the Utilization of Exhaust Gas Heat

摘要

An ideal homogensous boiling layer by thermal potential of unit of volume at identical resistance is considerably more convenient than a dense layer, especially in the zone of fully developed 'boiling'. For thermal processing of real polydispersion materials the boiling layer is more convenient than the dense one, in view of the absence of negative effect of admixtures of thin fractions on the resistance of heat exchangers, thanks to which the necessity of preliminary separation of same is done away with.
