Experimental investigation of self-excited combustion instabilities in a lean, premixed, gas turbine combustor at high pressure

Self-excited combustion instabilities in a high pressure, single-element, lean, premixed,
natural gas (NG) dump-combustor are investigated. The combustor is designed for optical
access and instrumented with high frequency pressure transducers at multiple axial
locations. A parametric survey of operating conditions including inlet air temperature and
equivalence ratio has been performed, resulting in a wide range of pressure fluctuation
amplitudes (p′) of the mean chamber pressure (pCH). Two representative cases, flames A …

An experimental investigation of self-excited combustion instabilities in a high pressure,
single-element, lean, premixed, natural gas dump-combustor is presented in this paper. The
combustor is designed for optical access and is instrumented with high frequency pressure
transducers at multiple axial locations. A parametric survey of operating conditions including
inlet air temperature and equivalence ratio has been performed, which presents a wide
range of peak to peak pressure fluctuations (p′) of the mean chamber pressure (pc). Two …
