The situation of implementing optimized retrofit for self-stabilized dual-channel burners and combustion system of boiler No.1 in Shimen Power Plant has been presented. Through optimized adjustment of the ignition belt and adjustment of inclination angle for the burners

the combustion stability in the entire burners' zone has been enhanced

the temperature of exhaust flue gas being lowered

combustion efficiency being improved by 0.7%

ecomomic effectiveness being obvious

providing refenenced and experience for further resolving the existing problems of comparatively bad counter-interference capability of combustion in boiler No.2 of the above-mentioned power plant. as well as similar problems in other power plants over all the country.
