Abstract

The objectives of this study are to determine the combustion characteristic and combustion efficiency of premixed flame jet impinging on a plane surface. The conducted of experiments were aimed at determining the effect of Reynolds number, equivalence ratio of the air/fuel jet, and distance between the nozzle and the plate (i.e nozzle-to-plate distance) on combustion characteristic and combustion efficiency of the flame jet system. A rapid and high heating rate, leading to short processing time, is one of the important requirements of heating processes. Direct gas flame impingement heating using hydrocarbon-air or hydrocarbon-oxygen flames is employed in an expanding range of industrial heating processes because of its rapid and high heating rate. The dominant mode of heat transfer is forced convection, and the flames are characterized by their elevated temperatures, which provide small but significant concentrations of dissociated species. Recently, rapid heating techniques have become increasingly popular because they offer the possibility of saving energy and improving the quality of the hot product. Furthermore, there has been an increase in the use of jet impinging flame heating in industrial field.
