Description

Recent studies have described and evidenced the enhancement of fundamental combustion parameters such as laminar flame speed due to the catalytic influence of H₂O with heavily carbonaceous syngas mixtures. These data have been used to demonstrate the effect of subtle changes in water loading in terms of delayed lean blowoff and primary emission reduction in a premixed turbulent swirling flame. The chemical kinetic data demonstrate the influence of H₂O on the employed laminar fuel behaviour. OH* chemiluminescence and OH planar laser induced fluorescence (PLIF) were also employed to optically analyse the changes in heat release structure resulting from the experimental addition of H₂O vapour to the combustor. Equivalent concentrations of liquid H₂O were introduced into the central recirculation zone of the premixed flame as an atomised spray to investigate the influence of phase changes on the catalytic effect. Optical intensity datafiles are included for vapour, spray and combined experiments. Normalised (dry, 15%O2) NO_x concentrations are also included in the dataset for all experiments.
