23/9/2009 · Efficiency is a very important criterion in Boiler selection and Design. Efficiency figure depends upon the type of boiler as well as on the type of fuel and it's constituents. For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 %.

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%).
