Trusted Engineering economizer for commercial heating


In today's cost-conscious industrial landscape, maximizing output while minimizing fuel costs is paramount. A boiler economizer serves as a valuable tool in achieving these objectives. This heat recovery device effectively preheats the incoming feedwater by utilizing waste heat from the flue gases exiting the boiler. By implementing an economizer, businesses can substantially reduce fuel consumption and consequently lower their overall operating expenses.



  • Economizers operate by capturing the residual heat from flue gases before they are released into the atmosphere.

  • This captured heat is then transferred to the incoming feedwater, raising its temperature and reducing the load on the boiler system.

  • The result is a reduction in fuel consumption as the boiler requires less energy to reach the desired steam temperature.

Investing in a boiler economizer offers several measurable benefits, including:
