摘　　要：针对天津大唐国际盘山发电有限责任公司3号锅炉近期飞灰含碳量偏高的现象,对其进行了燃烧调整试验,主要研究了磨煤机运行方式、燃烧器配风方式、炉膛氧量及煤粉细度的变化对飞灰含碳量的影响,并根据试验结果采取了相应的优化调整措施,使得3号锅炉飞灰含碳量降低到2%以下,取得了良好的效果,提高了机组运行经济性。For solving the problem of high carbon content of fly ash in the 3 boiler of Tianjin Datang International Panshan Power Generation Co. , Ltd, a series combustion adjustment experiments were conducted on operation mode of coal pulverizers, air distribution mode of burners, furnace oxygen amount and coal fineness. By taking optimization adjustment meas- ures basing on the experimental results, the carbon content of fly ash in the 3 boiler was reduced to under 2%, and the economical efficiency of the unit was improved.
