Catalytic Combustor for Small Gas Turbines: Combustor Development [PDF]
Volume 3: Coal, Biomass and Alternative Fuels; Combustion and Fuels; Oil and Gas Applications, 1989 As described previously in ASME papers, an effort has been underway to apply catalytic combustion for small gas turbines. To improve combustion efficiency at the engine operating conditions, two catalytic combustors have been developed. Both combustors showed high combustion efficiency and low NOx emissions in combustor rig tests. In engine tests, Type

Alternate-Fueled Combustor-Sector Performance—Part A: Combustor Performance and Part B: Combustor Emissions [PDF]
ISRN Mechanical Engineering, 2012 Alternate aviation fuels for military or commercial use are required to satisfy MIL-DTL-83133F or ASTM D 7566 standards, respectively, and are classified as “drop-in’’ fuel replacements. To satisfy legacy issues, blends to 50% alternate fuel with petroleum fuels are acceptable.

Small gas turbine combustor study - Combustor liner evaluation [PDF]
21st Aerospace Sciences Meeting, 1983 A reverse flow combustor liner constructed of Lamilloy (a multilaminate transpiration type material) is compared both analytically and experimentally with a conventional splash film-cooled design with the same combustor configuration. Comparison of selected critical combustor panels indicated that it was possible to maintain the liner temperature ...

Proceedings of the Combustion Institute, 2020 With developing interest in NH3 as a prospective energy carrier, combustor designs and fuelling concepts require optimisation to reduce NOx emissions. Through the introduction of staged combustor concepts, pathways have previously been identified that ...

Journal of the Global Power and Propulsion Society, 2018 Recently, because of environmental regulations, gas turbine manufacturers are restricted to produce machines that work in the lean combustion regime. Gas turbines operating in this regime are prone to combustion-driven acoustic oscillations referred as ...
