Application of Thermal Energy Storage to Process Heat Recovery, Phase III, Heat Exchanger Evaluation

摘要

The overall goals of the Phase III Heat Exchanger Evaluation are to develop data which will enable the design of a heat exchanger suitable for long-term continuous operation in the aluminum plant pollution control system environment and to assure that the installation of such a device will have no negative impact upon the existing processes. This heat exchanger's function is to recover reject process heat which can be stored and ultimately used as the heat source in a district heating system. A series of tests starting with small-scale experiments and expanding in magnitude to a production prototype is currently in process. The smallest scale testing is complete. Information gathered has been used to define a subscale heat exchanger. The subscale heat exchanger is currently being fabricated. Preparations for its installation are underway currently.
