A study of a large midwestern U.S. tire manufacturer was performed to determine where areas of energy conservation exist, and calculations were made predicting the costs of purchasing and installing energy-saving technology, the annual amount of energy saved, and annual cost savings from reduced energy use. The areas of energy conservation that were examined included insulation of tire molds, cogeneration, variable-frequency drives (VFDs) on the chilled-water pumps, a pressure-reduction turbine (PRT), and absorption refrigeration. The study predicted that it was very advantageous to both insulate tire molds where insulation had been removed over years of use and to install VFDs on the chilled-water pumps in the facility. The study suggested more investigation of the use of a PRT in place of the current pressure-reduction valve that provides steam at a lower pressure. Using cogeneration was a significant change that would require major infrastructure changes and downtime to the facility, but it predicted that significant cost savings would result. Absorption refrigeration could be used to successfully produce chilled water from the waste heat of the steam boilers, but the initial cost compared to the annual cost savings did not make this asuggested change.
