Flame Analysis Of Micro And Nano Flash Powder For Firework Applications

A. Azhagurajan, N. Selvakumar and Sriram Jeyakumar

Abstract: Flame height and width of flash powder used in firework manufacturing were observed as a function of their particle size. Mass consumption and flame propagation velocity were also calculated. Particles of 250, 150 and 75 micron size as well as nano-sized particles were used in the study. In addition, the performance analysis of the flash powder compositions was checked by manufacturing firecrackers. The noise level during bursting was measured and checked for correlation with the flame parameters.

Keywords: Fireworks, flash powder, nano, noise level.
