The smoke point has been shown to be quantitatively related to the molecular structure of hydrocarbon fuels. A fast technique of determining molecular composition of commercial and experimental fuels, in terms of carbon type structure, by using a proton nuclear magnetic resonance (H NMR) spectrometry has been described. By measuring the smoke point soot yields of a laminar diffusion flame with a group of fuels - all having a constant hydrogen to carbon ratio - it has been shown that neither the smoke point nor hydrogen to carbon ratio alone can describe the sooting propensity of turbine fuels. Obtained results indicate that smoke point and hydrogen to carbon ratio are complementary to each other in describing the sooting propensities of turbine fuels. This has been further tested using the available data in literature obtained from gas turbine combustors and diffusion flames.
