Fundamental characterization of alternate-fuel effects in continuous-combustion systems. Quarterly technical progress report, 1 July 1981-30 September 1981
The overall objective of this research program is to assist in the development of fuel-flexible combustion systems which can accommodate future alternate fuels derived from non-petroleum resources, with particular emphasis on liquid hydrocarbon fuels and gas turbine combustors. The program is divided into coordinated experimental and analytical efforts. The objectives of the experimental program are to obtain an improved understanding of the relationships among soot production, fuel nitrogen conversion, fuel properties, and combustor operating conditions in highly backmixed systems and to provide a data base for the development of corresonding analytical models/correlations. The approach has been to study soot production and fuel nitrogen conversion processes in several jet-stirred combustors, which provide reasonable simulations of the highly backmixed combustion environments found in gas turbine combustors, yet still retain sufficient experimental simplicity to control and characterize fundamental parameters. The objective of the analytical program is to provide modeling/correlation capabilities which can be used as design aids for the development of fuel-tolerant combustion systems. The approach has been to develop quasi-global chemical kinetic descriptions of the pertinent combustion processes and to incorporate these mechanisms into a modular gas turbine combustor model consisting of coupled well-stirred and plug flow reactors. Experimental efforts during the past quarter principally involved soot production experiments in the Variable Pressure Jet-Stirred Combustor and fuel nitrogen conversion experiments in the Jet-Stirred Combustor and the Liquid Fuel Jet-Stirred Combustor.
