The vigorously turbulent rich premixed flame is observed in a numerically simulated hydrogen jet lifted flame. The internal structure of the turbulent flame is investigated mainly by comparison with 1-D laminar flame structure. The analysis on the progress variable show that its dependency on temperature is not linear as expected in a single-step reaction model and only slightly different from that in 1-D laminar flame. The premixed combustion takes place at richer condition as the distance from the nozzle increases. In the very rich premixed flame, very high fuel consumption and heat release take place in low temperature side of the reaction layer compared with 1-D laminar flame. The deviation seems to come from the turbulent transport of chemical species.
