Boiler Efficiency - an overview | ScienceDirect Topics

Free ChatSep 05, 2020 · At £2,500 say, a new boiler that brings an energy saving of £40 per annum will not recoup its value. 9. Getting the highest efficiencies out of your existing systems. Boiler efficiency is of course important and may bring decent savings. However heating system efficiency is more important and can cost a lot less to achieve.

Free ChatFrom 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 …
