  • Boiler Efficiency - an overview | ScienceDirect Topics

    From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).Learn More
