Aiming at investigating the micro-mixing combustion characteristics of nitrogen diluted hydrogen-rich syngas at high pressures,the combustion model corrected at atmospheric pressure was adopted to ana-lyze the temperature field,flame shape and pollution emissions under conditions with different pressures, powers and equivalent ratios.The results show that,with an increase in pressure,the flame temperature and outlet temperature of the burner rose first and then dropped slightly;the flame width decreased gradu-ally while its height grew;the NOx emission indexes increased and tended to be smooth when the pressure increased to higher than 1 4 MPa.
