Title: Effect of fuel composition on NO x formation in high‐pressure syngas/air combustion

Journal Article · · AIChE Journal
DOI:https://doi.org/10.1002/aic.16170· OSTI ID:1432730

In this study, an experimental investigation of lean premixed syngas/air flames with H 2 /CO ratio of 1.0 and equivalence ratio of 0.5 has been conducted in a high‐pressure burner facility to investigate the effects of pressure and the presence of hydrocarbons on NO x speciation. Detailed NO x speciation measurements in the post‐flame region were conducted for various pressures up to 1.5 MPa (15 bar) using Fourier transform infrared (FTIR) spectroscopy. When the pressure is increased, NO concentration decreases while NO 2 increases due to pressure dependence of NO to NO 2 conversion. For a given pressure, the presence of hydrocarbons in syngas leads to an increase in NO x concentrations possibly due to prompt NO formation. Comparison of NO concentrations in presence of CH 4 at different pressures shows that the effect of CH 4 due to prompt NO formation is more dominant than the effect of pressure on NO. © 2018 American Institute of Chemical Engineers AIChE J , 64: 3134–3140, 2018
