Combustion characterization of fuel blends for power generation gas turbines

Laboratory measurements of flame speed, ignition delay time, and NOxformation over a wide range of fuel compositions and conditions, including the subsequent data analysis and chemical kinetics modeling, are performed at UCF. A discussion on the major tasks covers the autoignition measurements; flame speed measurements; chemical kinetics modeling; CFD modeling; NOxmeasurements; mechanism validation experiments; some of the primary objectives including the development of empirical correlations of flame speed and ignition times for immediate use by designers and project engineers, the assembly and calibration of full and reduced chemical kinetics models for more extensive predictions of flame speed, ignition, and NOxformation, and the demonstration of CFD models of one or more gas turbine combustors employing the kinetics mechanism developed; and test matrices formulated so that a wide range of fuel composition, stoichiometry, and engine conditions that can be incorporated into the empirical data in a relatively short time span. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
