Download or read book Effects of Fuel Nozzle Design on Performance of an Experimental Annular Combustor Using Natural Gas Fuel written by Jerrold D. Wear and published by . This book was released on 1972 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of various fuel nozzles were conducted with natural gas fuel in a full-annulus combustor. The nozzles were designed to provide either axial, angled, or radial fuel injection. Each fuel nozzle was evaluated by measuring combustion efficiency at relatively severe combustor operating conditions. Combustor blowout and altitude ignition tests were also used to evaluate nozzle designs. Results indicate that angled injection gave higher combustion efficiency, less tendency toward combustion instability, and altitude relight characteristics equal to or superior to those of the other fuel nozzles that were tested.

Download or read book Effect of Combustor inlet Conditions on Performance of an Annular Turbojet Combustor written by J. Howard Childs and published by . This book was released on 1947 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combustion performance and particularly the phenomenon of altitude operational limits was studied by operating the annular combustor of a turbojet engine over a range of conditions of air flow, inlet pressure, inlet temperature, and fuel flow. The combustor investigated was not the latest version of this combustor and the data are presented primarily because they are indicative of general trends and phenomena that apply to a large class of turbojet combustors.

Download or read book Comparison of Simplex and Dual orifice Fuel Nozzles with Ambient and Heated Fuel in an Annular Turbojet Combustor written by Donald F. Schultz and published by . This book was released on 1971 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A full-scale annular combustor was operated with simplex fuel nozzles of three flow ranges and with dual-orifice fuel nozzles. The dual-orifice nozzles provided combustion efficiencies within 2 to 3 percent of the peak values obtained with any of the simplex atomizers. A wide range of operating conditions including altitude relight, simulated takeoff, Mach 2.7 cruise, and Mach 3.0 cruise were studied. Measurements were made of combustion efficiency, pattern factor , flame radiation, smoke emission, and response to rapid increase in fuel flow. Fuel heated to 300 [degree] F (423 K) was used in many of the tests; heated fuel usually increased combustion efficiency.
Download or read book Evaluation of an Experimental Short length Annular Combustor written by Francis M. Humenik and published by . This book was released on 1973 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test program was conducted to evaluate an experimental short-length annular combustor that uses a one-side-entry dilution airflow concept. The combustor design features scoops on the outer liner for controlling the primary- and secondary-zone airflow distribution. Combustor inlet total pressures were limited to 62 N/sq cm (90 psia) with inlet-air temperatures from 590 K (600 F) to 890 K (1150 F). At a diffuser inlet Mach number of 0.25, the exit temperature pattern factor was 0.44 with an average exit temperature of 1436 K (2124 F) and a total pressure loss of 4.3 percent. At a diffuser inlet Mach number of 0.31, the exit temperature pattern factor was reduced to 0.29 with an average exit temperature of 1450 K (2151 F) and a total pressure loss of 6.1 percent. Nominal combustion efficiencies of 100 percent were obtained with the ASTM A-1 fuel. Exhaust gas emissions, smoke, and altitude relight data are included with exit-temperature profiles and distribution patterns.
