Measurement of major species concentration in kerosene combustion

A spontaneous vibration Raman scattering(SVRS) system for the simultaneous measurement of the major species concentrations in kerosene combustion was presented. The accuracy of SVRS was analyzed by measuring the major species concentrations in the air. The fluorescence characteristic of kerosene induced by 355 nm laser was obtained and analyzed. Under different burning conditions, the kerosene combustion was diagnosed by SVRS, the Raman spectra of the major species (N2, O2, H2O,CO2) in lean kerosene combustion were obtained, and the major species concentrations during the combustion process was calculated.
