Dynamic Response of Radial Swirl Burner
Global demand for cleaner, more compact and efficient energy systems has led to the development of Lean Premixed Gas Turbine (LPGT) Engines. Emissions from these engines contain less unburned fuels, CO, NOx among other pollutants. However, the use of LPGT Engine is hindered by critical thermo-acoustic combustion instabilities which among many problems is detrimental to the engine mechanical integrity. Hence, this research will examine the dynamic response of the premixed fuel experimentally using high speed, high resolution flow visualisation and acoustic measurements. The results from this study will contribute to the elimination of operational instabilities in LPGT engines.
