摘要
分析了燃烧系统改造前的运行状况和出现问题的原因,针对多劣质煤、多种类燃煤供应市场的状况,实施了锅炉燃烧系统改造,取得了较好的效果,实现了在燃用多劣质煤掺烧情况下锅炉水冷壁及屏式过热器受热面不易结焦的目标,保证了燃烧系统的安全稳定运行,提高了锅炉整体经济性能。
The operation state of the combustion system and the reasons of occurred problems before the combustion system reformation were analyzed.Aiming at the situation of the coal market,which supplies much inferior coal and much coal kinds,the combustion system of the boiler was reformed,and better effects were obtained.The target,which is to fire the blending much inferior coal and there is not serious coking to form on the water wall and the platen superheater heating surface of the boiler,was realized.The safe and stable operation of the combustion system was ensured,and the overall economic performance of the boiler was improved.
