Abstract:

Measurements were made of total radiant energy from flames for a series of pure hydrocarbons, varying widely in molecular structure and boiling point. The study was con ducted using the Phillips Microburner, which simulates conditions for combustion existing in an aircraft gas turbine engine i.e., a high intensity, turbulent-diffusion type, combustion process. The Microburner tests did not differentiate among hydrocarbons including all of the normal- and isoparaffins, the mono- and bicycloparaffins, and the straight and branch chain olefins having hydrogen contents above about 13 weight percent, heats of combustion above about 18,200, Luminometer Numbers above about 40, and ASTM Smoke Points above about 20 mm. At lower values, the total radiant energy increased rapidly with decrease in these properties. The hydrocarbons, other than those listed above, were rated in the following order of increasing flame radiation the cycloolefins, tetracyclododecane, tetralin and the alkylbenzenes, benzene and styrene, and methylnaphthalene. The results also show that fuel volatility was not a significant factor under the test conditions. Author
