摘要
针对中国石化仪征化纤股份有限公司热电生产中心220 t/h高压锅炉燃烧系统NOx排放质量浓度高达750～1 100 mg/m3的现状,对锅炉进行了低氮燃烧改造.改造后NOx排放质量浓度降到了350mg/m3以内,降幅达50％以上,起到了较好的NOx减排效果.
Aiming at the current status that the NOx emission mass concentration from combustion system in the 220 t/h high-pressure boiler of Sinopec Yizheng Chemical Fibre Co., Ltd. had gotten up to 750-1 100 mg/m3, a low-nitrogen combustion retrofit was conducted to the boiler, after which the NOx emission mass concentration was reduced by over 50% to be within 350 mg/m3, realizing a good NOx emission reduction effect.
