Abstract

In this study, two prediction models were developed to determine equilibrium compositions in the combustion products of a domestic boiler. These models are based on the Gibbs energy minimization and equilibrium constant methods. According to the domestic boiler standards (EN 15502-1 and EN 437), gaseous fuels (G20, G25, and NG) were selected to predict gaseous emissions. A novel investigation was realized for a domestic boiler's lean premixed burner in compliance with relevant standards. In the range of 0.6-0.9 equivalence ratio, the equilibrium compositions of the species were obtained.
