Advanced Catalytic Combustors for Low Pollutant Emissions
Abstract
The objective of this design was to evaluate the feasibility of employing the known attractive and distinguishing features of catalytic combustion technology to reduce NOx emissions from gas turbine engines during subsonic, stratospheric cruise operation. Six conceptual combustor designs employing catalytic combustion were defined and evaluated for their potential to meet specific emissions and performance goals. Based on these evaluations, two parallel-staged, fixed-geometry designs were identified as the most promising concepts. Additional design studies were conducted to produce detailed preliminary designs of these two combustors. Results of these design studies indicate that cruise NOX emissions can be reduced by an order of magnitude relative to current technology levels by the use of catalytic combustion. Also, these combustors have the potential for operating over the EPA landing-takeoff cycle and at cruise with a low pressure drop, high combustion efficiency and with a very low overall level of emission pollutants. The use of catalytic combustion, however, requires advanced technology generation in order to obtain the time-temperature catalytic reactor performance and durability required for practical aircraft engine combustors.
