Abstract

The present study has numerically investigated the flame—acoustics interactions in the turbulent partially premixed flame field under the IGCC—like combustion environment. Computations are made for wide range of overall equivalence ratios and thermal loads. Based on numerical results, the detailed discussions are made for the overall flame structure and the driving mechanism of combustion instability encountered in the partially premixed combustor.
