摘要

A study on effects of CO/H₂ ratio, H₂O dilution and pressures on the cellular structure of moist syngas flame was conducted using spherically expanding flames. Experimental conditions for the CO/H₂/H₂O/air mixtures are the pressures from 0.1 to 0.3 MPa, initial temperature of 373K and H₂O dilution ratios are from 0 to 0.15. Results show cellular instability is promoted at atmospheric pressure and suppressed at elevated pressure when H₂O is added into the mixture. In addition, critical radius increases with the increase of H₂O dilution ratio for the mixture with CO/H₂ ratio of 50/50 and changes little when CO/H₂ ratio is 20/80. Critical Peclet number decreases with the addition of H₂O and increases with the decrease of CO/H₂ ratio.
