Effects of heterogeneity of mixtures on gaseous emissions in premixed/prevaporized combustion
Abstract
A quasi-one-dimensional flame tube is used to evaluate the effects of experimental parameters on the emissions of NO(x), CO and HC from a 'premixed/prevaporized' combustor. Experiments have been conducted using the iso-octane over a wide range of equivalence ratio for inlet air temperatures of 450, 550 and 650 K. An increase of homogeneity by improving prevaporization of the atomized fuel results in a drastic reduction of NO(x) emission and in appreciable decrease of CO and HC emissions at fuel-lean conditions. A correlation of emission index for NO(x) at complete fuel prevaporization with adiabatic flame temperature is presented.
