STUDY OF TURBOJET MAIN BURNERS FOR USE WITH CONTAMINATED FUEL.

Abstract

Thirty-three tests totaling 34.6 hours were made with three rig builds of the vaporizing center tube burner can. Rig 20621-1 accumulated 8.5 hours of operating time using contaminated JP-5 fuel; rig 20621-2 accumulated 16 hours of operating time using clean JP-5 fuel; and rig 20621-3 accumulated 10.1 hours of operating time using clean JP-5 fuel. None of the burner cans showed any damage after testing. One tube was operated for 5.25 hours using MIL-E-5007B contaminated JP-5 fuel. From this limited testing, it appears that contaminants have no effect on increasing the rate of carbonaceous deposit buildup on tube internal walls, or in varying significantly the fuel heat transfer coefficients during testing. The effect of carbonaceous deposits on heat transfer coefficients, in general, is to reduce the coefficient. A correlation between deposit thickness, deposit location and variation in coefficient is being sought, using the data obtained in this study. This will be discussed further in the progress report for the next report period. (Author)
