Premixed, lean burn combustion research has been focused for years on extending the lean flammability limit while maintaining both stable ignition and turbulent flame propagation. Burning speed is a fundamental physicochemical property of homogenous fuel/oxygen/diluent mixtures. It determines the rate of energy released during combustion and is of basic importance for developing and testing chemical kinetic models of hydrocarbons. The burning speed and flame structure of blends of reformed fuel and Methane-air mixtures have been studied using two similar constant volumes; a cylindrical vessel with end windows and a spherical chamber. The Experiments were conducted for a range of reformed fuel blends (20–80%) as well as mixture equivalence ratios (0.4–0.6). The burning speed results clearly define the regime of stable flame propagation for equivalence ratio/reformed fuel blend combinations.
