1、 I 摘 要 循环流化床锅炉是近几十年发展起来的一种新型燃烧设备，其具有燃料适应性广、有 利于环保、负荷调节性好、燃烧热强度大、炉内传热能力强等优点。所以，其一经推出就 在世界范围内得到了广泛的应用。特别是在中国，循环流化床锅炉技术在近几十年取得了 长足的进步。 本论文根据多维电厂 3 台 150t/h循环流化床锅炉机组的实际运行情况，从循环流化床 锅炉的燃烧与运行调整方面进行了较为深入的研究，在循环流化床锅炉的启动运行、燃烧 调整及优化控制方面提出了许多实用性的方法。 论文介绍了多维电厂 150t/h循环流化床锅炉的主要设计参数和整个锅炉系统，并进一 步介绍了循环流化床锅炉的故障处理。 论文
2、分析了流化床锅炉的经济运行和故障处理，并进一步对循环流化炉锅炉的运行和 调整进行了研究，在循环流化床锅炉的负荷调整、床温调整、床压调整、返料量调整、风 量调整、SO2和 NOx 的排放量控制及给煤粒度调整方面，提出了实用的调整方法。 论文针对煤种突变造成对循环流化床锅炉燃烧的影响、锅炉结焦对燃烧的影响、床料 粒径及分布变化对运行的影响等各种常见故障进行了研究分析，提出了处理这些故障的实 用方法。 关键词：循环流化床；调整试验；燃烧调整；经济运行；故障处理 II Abstract The CFB is the new combustion equipment which is developed
3、 in the recent years, it has the advantages of be widely adapt to fuels,be good for environment,load adjustment well,burning intensity is big,heat transfer is strong in the firebox and so on.So,it is widely applied in the world.Especially in China,the technolog of CFB is made great progress in the r
4、ecent years Based on the three 150t/h CFB (Circulating Fluidized Bed) boilerspractical operating situations of DuoWei Power Plant, The burning and operating adjustment for CFB boiler were studied in this paper, and many practical ways about the CFB start-up, running, burning adjustment, and optimizing control were put forward. The paper introduced the main design parameters and the whole boiler system and its trouble elimination of the CFB. It analyzed economical operation and trouble elimin
