“Manufacturing is more than just putting parts together. It’s coming up with ideas, testing principles and perfecting the engineering, as well as final assembly.” – James Dyson
EFFICIENCY // Aluminum Recovery System
Driven by new regulations as well as consumer performance requirements, there has been aglobal increase in demand for a broad range of cast, extruded and machined aluminum parts. Aluminum parts producers are looking to metals recovery systems to control costs of primary and secondary aluminum purchases and to mitigate their operating cost by capturing value from byproducts.
A perfect example of the cost savings benefits of secondary heat recovery in aluminum scrap recycling can be found in an installation at a merchant metals recycling operation in Arkansas. The existing system was an early design pre-treatment system with rudimentary drying technology. Epcon’s custom engineered system upgrade included an innovative design of a thermal oxidizer for this application equipped with a quad down-flow inlet plenum, axial mounted down-fired burner as well as primary and secondary heat exchangers. This configuration maximized turbulence in the combustion chamber, resulting in excellent destruction efficiency and protected the burner from potential particulate carryover.
Recognizing that a 1% deviation in contaminant levels can translate to more than a 2% move in metals recovery, highlights the value in investing in the latest recovery technologies. Whether for a new system or retro-fit of an existing plant, focusing on emissions performance rate limiting factors will insure overall project success.
