Advanced Fuel Development and Fuel Combustion Delivery Order 0007: Abatement of Soot from Military Gas Turbine Engines via Fuel Additives

摘要

The technical objective of this program was to develop fundamental understanding of the complex interactions of additives with the processes that lead to PM emissions from military gas turbine engines and to use that fundamental understanding to select and investigate the most promising additives for reducing PM emissions. Because of the inherent complexity of the combustion processes within gas turbine combustors and great difficulty in making measurements inside combustors, it was not possible to achieve the technical objective of this program by making measurements in gas turbine combustors. Furthermore, due to the complexity of the combustion process in a gas turbine combustor, no single laboratory flame or reactor will suffice as a model for a combustor. Therefore, multiple laboratory devices were applied to study the effects of additives on soot formation processes. These devices included a shock tube, a well-stirred reactor, premixed flames, diffusion flames, a spray flame, and a high pressure turbulent reactor. Experiments were performed at Penn State in four of these devices: a premixed flame, a co-flow diffusion flame, a spray flame and the high pressure turbulent reactor.
