Effects of propane pyrolysis on basic flame structures of non-premixed jet flame

摘要: Recently, high temperature combustion techniques have been extensively adopted to improve thermal efficiency of devices. When the is sufficiently high, fuel pyrolysis may occur and then flame structure can be affected. Thus, understanding at coupled with essential design burners operated in environments. In this study, propane was heated up 1100 K using an electric heater, characteristics its effects on non-premixed jet flames were experimentally investigated room temperature. Normalized volume flow rates components measured regarding pyrolysis. The normalized increased significantly through process, they agreed numerical results based ordinary chemical mechanism. Variations height soot region compared for Conclusively, spite significant growth rate by pyrolysis, not On contrary, slightly extended This study will help extend especially conditions.
