Book Description

A 27-inch (68.6-cm) long rectangular combustor segment consisting of an array of 48 combustor modules was tested to determine its performance. Each module mixed and swirled fuel with air and stabilized combustion. Test conditions were inlet temperatures of 600 [degree] and 1150 [degree] F (589 and 894 K), a pressure of 3 atmospheres, and reference velocities to 160 ft/sec (48.8 m/sec). Results were combustion efficiencies of 100 percent, a pressure loss of 5.4 percent for an inlet Mach number of 0.25, a heat release rate of 11.86x10 [power of six] Btu/(hr)(ft [power of three] )(atm) for a temperature ratio of 2.5, and pattern factor spans of 0.30 to 0.37 and 0.22 to 0.28 with 600 [degree] and 1150 [degree] F (589 and 894 K) inlet air temperatures, respectively. Altitude blowout and relight data, as well as a comparison of results with a longer combustor, are also included.
