Abstract: In this paper, we present combustor acoustics in a high-pressure liquid-fueled rich burn—quick quench—lean burn (RQL) styled swirl combustor with two separate fuel circuits. The fuel circuits are the primary (which has a ...

Abstract: Lean, premixed combustor designs have almost completely replaced nonpremixed combustors for industrial gas turbine applications where NOx emissions are regulated. Nonetheless, these designs have also introduced turndown ...
