The performances of a cylindrical meso-scale swirl combustor having a volume of about 254 mm3 and working at 3 atm have been experimentally investigated. The analysis has been carried out for different equivalence ratios. In these experimental conditions, information about stability and efficiency of the meso-combustor were derived. To this purpose Fourier Transform Infrared Spectroscopy measurements have been carried out at the exhaust of the combustor. The gas concentration results obtained with this analysis are then compared with measurements carried out with commercial gas analyzer
