  • Thermal Design of Economizer for Waste Heat Recovery Boiler

    Economizers are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it. One of the most cost-effective ways of improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. The mainLearn More

  • Water Handbook - Preboiler & Industrial Boiler Corrosion

    Economizers help to improve boiler efficiency by extracting heat from flue gases discharged from the fireside of a boiler. Economizers can be classified as nonsteaming or steaming. In a steaming economizer, 5-20% of the incoming feedwater becomes steam. Steaming economizers are particularly sensitive to deposition from feedwater contaminants Learn More
