Development of an evaporator for industrial heat pumps capable of recovering heat from contaminated sources. Phase 1. Final report, October 1, 1984-July 31, 1985
Industry regularly loses large amounts of potentially recoverable energy by venting or condensing steam that cannot be used in the plant because it is too low in temperature and too contaminated for reuse. A heat pump could raise the temperature of this energy to a usable level if a suitable heat exchanger were available for extracting the heat from the contaminated steam. The objective of this program is to develop a heat exchanger uniquely configured for this purpose. Its availability would greatly increase the number of viable applications for industrial heat pumps. The heat exchanger under development uses falling-film heat transfer on both sides of vertical tubes to generate clean vapor by condensing contaminated steam. This approach provides a self-cleaning action and makes maximum use of the available temperature difference between the condensing contaminated steam and the boiling heat pump fluid. This report describes the work performed under Phase I of the program in which a laboratory prototype heat exchanger was designed, built and tested, and an economic evaluation of the concept was made.
