abstract

This paper is a review of current research and development work in gas turbine combustion and fuels based on publications in the open literature and papers and reports supplied to the author by various gas turbine manufacturers on their current combustor research and development programs. Both aircraft and industrial applications are considered for the two major topics that are covered in the paper, alternative fuels and computer modeling, and for the illustration of two combustor component research and development activities. For aircraft applications, alternative fuel studies have centered on “heavier” fuels and have shown physical properties of the fuels which influence atomization and vaporization to be of primary concern regarding ignition and flame stability while chemical properties are more important to particulate emissions, heat transfer and liner durability considerations. For industrial applications, the use of medium to low heating value fuels and coal slurries have received much attention with particular emphasis on fuel delivery and mixing modifications within the combustor to accommodate these fuels. Computer modeling continues to play an increasingly important role in combustor development; currently the so-called “TEACH” based codes and their offspring are used for the majority of the computational fluid dynamics applications for gas turbine combustors. However, much work is being directed towards advanced differencing schemes, complex boundary fitting programs and proper treatment of inlet and boundary conditions in addition to studies devoted to advancing the physical submodels that are incorporated in the codes. Finally, two examples of research and development for specific design considerations are illustrated with a discussion of recent efforts on staged combustion for NOx control and on fuel injection.
