RISSpatial Temperature Measurements in a Swirl-Stabilized Hydrogen–Air Diffusion Flame at Elevated Pressure Using Laser-Induced Grating Spectroscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser-induced grating spectroscopy (LIGS) is applied, for the first time, to a swirling nonpremixed hydrogen–air flame in a high-pressure combustion facility. A portable LIGS unit is used to probe 35 different axial and ...
Influence of Variable Swirl on Emissions in a Non-Premixed Fuel-Flexible Burner at Elevated Ambient Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As alternative fuels are designated for future energy applications, flexible combustor designs require considerable development to ensure stable operation with reduced NOx emissions. A nonpremixed variable swirl burner was ...
Catalytic Influence of Water Vapor on Lean Blow-Off and NOx Reduction for Pressurized Swirling Syngas Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has become increasingly cost-effective for the steel industry to invest in the capture of heavily carbonaceous basic oxygen furnace or converter gas, and use it to support the intensive energy demands of the integrated ...
Characterization of Additive Layer Manufacturing Swirl Burner Surface Roughness and Its Effects on Flame Stability Using High-Speed Diagnostics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, two Inconel 625 swirl nozzle inserts with identical bulk geometry were constructed via additive layer manufacturing (ALM) for use in a generic gas turbine swirl burner. Further postprocessing by grit blasting ...
Spatial Temperature and Water Molar Concentration Measurements Using Thermal and Electrostrictive Laser-Induced Grating Spectroscopy During Operation of a Swirl Burner at Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser-Induced Grating Spectroscopy (LIGS) was applied in a high-pressure combustion facility. Instantaneous (sub-μs), spatially resolved (within 5 mm) measurements of temperature and molar fractions of water were obtained ...
