Boiler Efficiency - an overview | ScienceDirect Topics

The improvement in the boiler efficiency depends on the flue gas temperature. • Use economizers to transfer energy from stack flue gases to incoming feedwater. As a rule of thumb, a 1% increase in the boiler efficiency is expected for each 5°C (9°F) increase in the feedwater temperature. •
