Boiler Economizer Operation

Boiler Economizer Systems

• Economizers reduce energy costs by recovering Btu lost in boiler exhaust waste heat. • Typical economizer applications are: preheating boiler feedwater, make-up water, hot water return loop. • Typical payback of an installed economizer is 6 months to 3 years (equivalent to 75% ROI per year of boiler operation).

Boiler Cycling Considerations - Babcock & Wilcox

Boiler Cycling Considerations. Many fossil fuel-fired boilers are now experiencing load cycling or on/off cycling operation. These modes of operation involve cycling a unit on and off line or reducing loads to absolute minimums in response to varying load demand. This can be caused by daily or weekly load shifts experienced on nights and

What is Function of Economizer Boiler..? - alwepo

May 27, 2021 · Boiler economizer is a device that uses a portion this remained energy of the flue gas to heat up inlet water (feed water) to the boiler. Since the heat energy is given to the water before it gets fed to the boiler, the requirement of fuel for producing steam is optimized. Because of that, we call this device as an economizer.
