Energy Recovery Heat Exchanger

Recuperators recover heat from waste gases to preheat air used for combustion in the furnaces/process. This reduces fuel consumption, increases flame temperature and improves furnace efficiency. Recuperators reduce upto 40% of the fuel consumption compared to cold air combustion.Combustion air preheats up to 750°C available.

Lean fuel gases and other process gases can also be preheated along with combustion air.



We also preheat fuel gasses like BF gas and producer gas. We have the widest range of custom designed and commercially viable solutions for almost every application.

We are among the world leaders in Heat Recuperation Technology with over 1600 installations worldwide. We provide recuperators for various industries to recover waste heat from industrial exhaust gases in an easily usable manner. Our recuperators preheat the combustion air from fuel gases to recycle the waste heat back to the furnaces. It saves fuel, increases flame temperature and improves furnace efficiency. Our recuperators are made from high quality materials such as durable stainless steel and other exotic alloys. At Eastern we offer customized solution for all recuperators to suit the client’s need.

We provide 100% custom designed recuperative solutions for all industries and application making your business eco friendly and more profitable. We give you one of the fastest deliveries from our own ISO-900 certified manufacturing facilities. We maintain a good stock of standard input materials like pipes, tubes, plates, etc. and use a variety of materials to size solutions as per the available space.

We provide customized solutions and help you to choose the type of recuperator suitable to a process considering parameters like dust in the flue gasses, flame, unburnt fuel, flue gas temperatures, allowable pressure drops on the heating and heated medium available space etc.

Flue gas temperature is 800 ℃ and fuel cost is INR. 35.00/litre. The furnace is operated 24 hours/day, 300days/year and the fuel consumption is 1000 lit/hour. For comparison we initially preheat combustion air to 350 degrees Celsius and then increase it to 600 ℃.

  • For air preheat at 350 ℃ savings is approximately 15%

Your Estimated Savings With:

1000 lit/hr*30Rs./lit*15%*24hrs*300days/year=Rs.3.24 crores.

  • For air preheat at 600 degrees Celsius, savings is approximately 29%

Your Estimated Savings With:

1000 lit/hr*30Rs./lit*29%*24hrs*300days/year=Rs.6.26 crores.

So, you can see how we help you save money by reducing fuel consumption. EASTERN’s Recuperators also provide additional benefits, such as:

  • Better Combustion Efficiency
  • Higher Flame Temperature
  • Better Product Heating
  • Higher Furnace Output
  • Lesser Emissions
