Abstract

The C2abundance in flames at atmospheric pressure is reported for three fuel-rich combustion environments: acetylene/oxygen, Liquid Petroleum Gas (LPG)/air and methane/air flames. Measurements have been based on spectrographic and two-dimensional Laser-Induced Fluorescence (LIF) of the Δv = -1 d3Πg-a3Πuband. The oxyacetylene flame was utilized to establish a comparison with literature data and absolute values, calibrated through Rayleigh scattering, were found to be distributed within the 1014cm-3range. The induced emission from two Bunsen flames fed with LPG/air or methane/air was also investigated. Accumulated acquisitions were necessary to detect small C2quantities in the order of 1010cm-3concentrated on the flame front.
