Abstract In order to investigate the possible use of methane (CH4)-ammonia (NH3) blends as a low carbon fuel, the combustion characteristics of expanding spherical premixed CH4-NH3/air flames are studied, measuring and predicting their laminar burning velocities (SL∞), Markstein numbers (Ma) and structure. Results show that the premixed CH4-NH3/air flames are thicker and propagate slower than the pure CH4/air flames, with reduced carbon dioxide (CO2) emissions. Meanwhile, both flames are cellularly stable for the present various test conditions, showing 0.3
