  • Common Maintenance Issues for Economizer - CFBC Boilers India

    2021-9-8u2002·u2002An economizer is a tubular heat exchanger used to preheat the boiler feed water before it enters the steam drum. The flue gas exiting the boiler carries a lot of heat. The economizer utilizes this heat to heat the water entering the boiler. The water is preheated in the economizer in the liquid phase at elevated pressure. Function of the economizer

  • Boiler Economizer: Boost Your Boiler's Performance I RasMech

    2021-3-3u2002·u2002Summary. Economizers lower the consumption of fuel for a given steam demand. They also reduce thermal stress in the boiler and add heat transfer surface area to the boiler system. 'By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.'.
