Melting for Non-Ferrous
Innovative technologies for low-cost, high-efficiency melting
Covai Air Products’ range of oxy-fuel technologies allows non-ferrous melting operations to use less fuel, achieve higher production rates, and reduce flue gas and particulate carryover. By completely or partially replacing combustion air with oxygen, the nitrogen in the air can be reduced or eliminated from the process, keeping it from carrying valuable heat up the stack and making more heat available to melt your non-ferrous materials.
Many different types of furnaces are used in non-ferrous melting operations, including tower furnaces, rockers, induction, rotaries, and reverbs. Each of these furnaces requires a different approach to oxy-fuel burner design to meet its design consideration and heat input needs.

Leveraging Experience and Innovative Technology to Optimize a Wide Range of Melting Operations
By customizing an oxy-fuel solution for your specific operation, we can match the heat input, flame shape and length, and heat release profile to the needs of the furnace to which it is being applied and help you reach the operational goals of that furnace. Production rate increases of 25-40% are common, with increased fuel efficiency and reduced flue gas volumes of 50% or more. This allows for much less downstream handling and lower flue gas temperatures.
Covai Air Products can supply the custom-designed burners as well as the flow controls, data acquisition, and smart analytics to optimize and track furnace performance. For production increases, very short paybacks of less than 6 months are often achieved.
