Flame Characteristics and Application of Flameless Combustion

Guillou, Erwann

Abstract Details

2008, MS, University of Cincinnati, Engineering : Aerospace Engineering.
Flameless combustion is a technique obtained by operating at high level of turbulence and temperature of oxidizer higher than the autoignition temperature of the air and fuel mixture. Lately, it has received much attention because of its benefits in terms of energy saving and low NOX emission rate. This thesis aims to collect information, both in theory and practice, which can be useful in understanding the change of combustion regime under typical conditions. An overview of the main motivations to provide new combustion systems until the development of flameless combustion and its interesting characteristics is first presented. An experimental flameless burner, developed from the collaboration between the University of Cincinnati and Goodrich Turbine Fuel Technologies, is then investigated under atmospheric gas turbine engine conditions. The experimental results are subdivided in two parts: first, the characterization of the burner under thermodynamic influences and then, the presentation of qualitative and quantitative results acquired over several gaseous and liquid flames which determines the effect of fuel properties on flame characteristics. At high preheated air temperature and high pressure drop, it was shown that flameless combustion occurred under very stable conditions. The fuel chemical properties were found to have a subtle effect on the flameless oxidation of fuel with notably an interesting behavior under butane atomization. All the results were finally conclusive on a potential application of such a regime of combustion to gas turbine engine.
