Abstract

A planar laser induced fluorescence (P LIF) technique is applied to quantify nitric oxide (NO) concentration in a premixed bunsen burner with a CH4 -air flame doped with NO (up to 1300 ppm). This experimental data will be used as the calibration method for quantitative in-flame NO measurements in a high-pressure generic swirl burner at Cardiff University’s Gas Turbine Research Centre. Methodology of modelling premixed bunsen burner combustion experiment in CHEMKIN for predicting NO emissions in a wide variation of premixed methane flames is also described here. Chemical kinetics simulation results from a wide range of fuel flow rates have been compared and analysed with the experimental data in this paper. Our open bunsen burner flame experienced about 15 – 25% reduction in seeded NO level at 25mm above the burner exit. Calibration curves were obtained for both online and offline by measuring NO -PLIF intensity at varying level of NO seeding. These results from both the LIF and simulations will complement each other in subsequent works.
