Abstract: This study presents the effects of O2 enrichment and CO2 (carbon dioxide) dilution on laminar methane flames. For that purpose, the following procedure was followed: i) measurements of laminar methane flame velocities carried out in a stainless steel combustion chamber at atmospheric pressure and 300 K; ii) calculations and comparison with experiments of laminar flame velocities to validate the reaction mechanism; and iii) simulations in larger ranges of flames conditions near to gas turbine conditions: premixed methane–air flames, preheated inlet temperature (To = 600 K) and pressures ranging from 1 to 8 bar. Lean, stoichiometric and slightly rich conditions were studied as the equivalence ratio was varied from 0.7 to 1.1. Both influences of the oxygen enrichment and CO2 dilution are discussed.
