Experimental clean combustor program, Phase 2. Final report

Technical Report ·
OSTI ID:7116590
; ;
The primary objectives of this three-phase program are to develop technology for the design of advanced combustors with significantly lower pollutant emission levels than those of current combustors, and to demonstrate these pollutant emission reductions in CF6-50C engine tests. The purpose of the Phase 2 Program was to further develop the two most promising concepts identified in the Phase 1 Program, the double annular combustor and the radial/axial staged combustor, and to design a combustor and breadboard fuel splitter control for CF6-50 engine demonstration testing in the Phase 3 Program. Noise measurement and alternate fuels addendums to the basic program were conducted to obtain additional experimental data. Twenty-one full annular and fifty-two sector combustor configurations were evaluated. Both combustor types demonstrated the capability for significantly reducing pollutant emission levels. The most promising results were obtained with the double annular combustor. Rig test results corrected to CF-50C engine conditions produced EPA emission parameters for CO, HC, and NO/sub x/ of 3.4, 0.4, and 4.5, respectively. These levels represent CO, HC, and NO/sub x/ reductions of 69, 90, and 42% respectively from current combustor emission levels. The combustor also met smoke emission level requirements and development engine performance and installation requirements.
