Abstract
An experimental study of laminar burning velocity and flame stability lean limit of hydrogenadded, preheated ethanol vapor-air flame is presented. The ethanol vapor-air premixed burner flame is obtained using gas mixture of initial temperature 112°C and 159°C. Laminar burning velocities at the initial temperature of 159°C are higher than those of 112°C in all range of the equivalence ratio. Hydrogen addition decreases the flame stability lean limit of the equivalence ratio from 0.66 to 0.27 and increases the laminar burning velocities, in comparison with the same lower heating value mixtures without hydrogen. Lower heating value decreases from 1.84 MJ/kg to 0.99 MJ/kg in the ethanol vapor-air mixtures at the lean limit.
