It is pointed out that fuel preparation, ignition, flame spreading, and flame stabilization are important considerations in the design of gas turbine engines. It is discussed how changes in the major properties of alternative fuels will affect atomization, ignition, flame spread, and lean blowoff in gas turbine burners. It is found that it is primarily the physical properties of the fuel which influence the performance parameters. Studies have shown that ignition is strongly dependent on fuel volatility and viscosity. A graph showing the influence of atomization quality on ignition limits is presented. For all fuels considered the atomization quality is found to be markedly inferior to that of normal kerosine, indicating that problems of ignition and lean blowoff will be more severe. The correlations predict that jet fuels derived from shale oils, tar sands, and coal syncrudes will pose more serious problems of atomization than similar petroleum-based fuels.
