Abstract
ABSTRACT
A series of experiments were done on a vertical EV burner with a constant coflow air
of 873 L /min in order to investigate the impact of fluidics insertion technique on the
temperature field and flame structure. The flow rates of fuel (LPG/ Ar) and air were
measured using calibrated rotameters. The different volume ratios of the fuel
constituents were admitted via three solenoid valves at the entry section of each
stream prior to mixing and monitored using a lab view program. The axial
temperature profiles at different operating conditions were measured using a bare
(type S) thermocouple. Flame images were obtained, before and after fluidics
insertion using a high resolution digital camera. The experimental program aims at
identifying and analyzing the changes in flame characteristics (flame length, axial
profiles of mean gas temperature, NOx concentration and overall combustion
efficiency) resulting from the insertion of fluidics while considering different
proportions of the fuel constituents. The results obtained indicate the following: it was
noticed that in most cases of pure LPG only, and other mixtures of argon the images
shows increase in both the length and luminosity of the flame as a result of higher
degrees of swirl due to the fluidics insertion while the temperature profiles of the
different flames were changed. It was indicated that NOx trend was decreased by
50% while the combustion efficiency was improved by 2.5%.
