Use of Thermal Energy Storage to Enhance the Recovery and Utilization of Industrial Waste Heat
MetadataShow full item record
The recovery and reuse of industrial waste heat may be limited if an energy source cannot be fully utilized in an otherwise available out of phase or unequal capacity end-use process. This paper summarizes the results of a technical and economic evaluation involving process data from 12 industrial plants to determine if thermal energy storage (TES) systems can be used with commercially available energy management equipment to enhance the recovery and utilization of industrial waste heat. Results showing estimated installed costs, net energy savings, economic benefits, and utility impact are presented at both single plant and industry levels for 14 of 24 applications having after tax ROR's in excess of 20 percent. Maximum energy and cost savings for 9 of these 14 systems are shown to be conditional on the use of TES.
