<br/><br/> This study is devoted to investigate the performance of the CFCN burner at higher level of turbulence closer to many practical applications. The stability characteristics are studied. In addition, the flow field and temperature field are experimentally investigated above the conical nozzle exit using 2D PIV and type B thermocouple, respectively. The flame stability is slightly improved using the present burner configuration. The NG flames exhibit higher stability than those of the LPG. The centerline axial velocity increases in reactive case by a factor of 1.5 - 4 higher than that of the non-reactive case. Moreover, the reactive case reaches a reduction in the turbulent Reynolds number by a factor of 4 - 5.5
