Abstract

A simple and low-cost instrument that non-intrusively measures the real-time fuel-to-air ratio (FAR) in a gas turbine combustor was developed. Initial application of this instrument was to obtain time-resolved measurements of the FAR in the premixer of a lean premixed prevaporized (LPP) combustor at inlet air pressures and temperatures as high as 17 atm 800 K, with liquid JP-8 as the fuel. Results quantitatively show the transient nature of the local FAR inside a LPP gas turbine combustor at actual operating conditions.
