Industries - Aluminium
Eastern designs and manufactures custom recuperators and heat exchangers engineered specifically for aluminium melting furnace operations. In melting, holding, and tilting furnaces, flue gases exit at temperatures between 700°C and 900°C — and without a waste heat recovery system, that energy escapes entirely through the exhaust stack. As a result, our aluminium melting furnace recuperators capture this heat and return it as preheated combustion air, directly accelerating the melt cycle, improving furnace productivity, and cutting fuel consumption by up to 40%. Eastern serves leading aluminium producers including Hindalco, Fives North American, and CEL — supplying proven heat recovery systems to aluminium plants across India and worldwide.

How Heat Recovery Works in an Aluminium Melting Furnace
In an aluminium melting furnace, large volumes of fuel are burned to reach and maintain the temperatures needed to melt, hold, and process aluminium. However, a significant share of that energy — often 40 to 60% — exits as hot exhaust gas rather than contributing to the melt. Without a recuperator, this heat escapes through the flue stack on every production cycle.
Eastern’s heat exchangers intercept the hot exhaust gas as it leaves the furnace. They use this captured heat to preheat incoming combustion air before it enters the burner. As a result, the aluminium melting furnace reaches higher temperatures faster, using less fuel per tonne of metal processed. Furthermore, faster melt cycles mean higher furnace throughput, lower energy cost per batch, and improved overall plant productivity.
Why Aluminium Plants Rely on Eastern for Melting Furnace Heat Recovery
Eastern engineers each recuperator to match your exact furnace type, capacity, and fuel specification. Because aluminium melting furnaces — including tilting, holding, and stationary types — operate under different thermal and pressure conditions, our systems are custom-designed rather than generic. In addition, Eastern factory-insulates every unit and supplies it ready to install, with mounting options that allow direct attachment to the furnace body.
Our aluminium melting furnace heat exchangers deliver:
- Up to 40% reduction in fuel consumption across melting and holding cycles
- Faster melting through higher combustion air preheat temperatures
- Higher furnace production per tonne of fuel consumed
- Suitable for melting, holding, and tilting furnaces of all capacities
- Simple installation with direct furnace-mount option — no major structural changes
Furthermore, Eastern provides complete installation supervision and after-sales support throughout the system’s life. Eastern manufactures every heat exchanger at our ISO 9001:2015-certified facility in Kolkata, meeting international quality and safety standards for aluminium industry applications. Eastern’s systems also support compliance with energy efficiency targets set by the Bureau of Energy Efficiency, Government of India.
