Thirty-six tests totaling 40 hours were made with the first rig build of the vaporizing center tube burner can. After this period, the burner can was in perfect condition. The burner can was operated over a range of values for inlet air mean total temperature TT3 from 528 to 1244 F and values of delta T rise from 355 to 1827 F at values of inlet air mean total pressure PT3 from 40.6 to 52.1 in. HgA. Values of combustion efficiency and combustion system total pressure loss ranges from 75.3 to 101.5 and from 6.19 to 12.10, respectively. Fourteen tests were made with PWA-523 fuel using one PWA-1060 Inconel and two Inconel-X tube test sections. A tube burnout occurred with the PWA-1060 material tube section when, during a power supply checkout, the power level caused the maximum allowable tube wall temperature to be exceeded momentarily. During the 13 tests with the Inconel-X test section, both non-boiling and boiling regime excursions were made. Author
