Ball Metal Beverage Container Corp. operates an aluminum beverage can manufacturing plant at Wallkill, NY. In 2004 a new Regenerative Thermal Oxidizer (RTO) was installed to control emissions from process cure ovens. An incentive from the New York State Energy Research and Development Authority (NYSERDA) was instrumental in this project, designed and implemented by MEGTEC Systems Inc., to recovery 1.9 MMBtu/hr from the RTO and reuse in the manufacturing process. During the first year of operation, the system recovered 1.3 MMBtu/hr. The under-performance was due to particulate buildup on the heat exchanger. This paper discusses hurdles and strategies to deploying RTO heat recovery, critical roles played by MEGTEC and NYSERDA, project results, lessons learned, and how the project affected Ball's energy efficiency program.
