Stack Losses – General Methodology. Calculating boiler stack losses consists of six steps. The calculations described below form the basis of the Boiler Efficiency Calculator. Since stack losses depend on fuel composition‚ firing conditions and flue gas temperature more detailed descriptions of the steps are available for five fuel types.
