在总结国产100MWCFB锅炉设计制造与运行经验的基础上,研究设计了具有自主知识产权的国产200MW循环流化床(CFB)锅炉。对其炉型特点、关键部件及锅炉岛系统的设计进行了详细分析讨论,并结合分流式回灰换热器的设计提出了复合炉型的设计思想和技术方案,以期为发展我国大型CFB锅炉技术及工程应用提供全面的技术支持。
On the basis of summarizing the design, manufacture and operation experience of domestic 100 MW CFB boilers, the domestic 200 MW circulating fluidized bed (CFB) boilers with independent intellectual property rights are researched and designed. The characteristics of the furnace, the key components and the design of the boiler island system are analyzed and discussed in detail. Combined with the design of the split ash return heat exchanger, the design idea and technical scheme of the composite furnace are put forward in order to develop the large CFB boiler Technical and engineering applications to provide a full range of technical support.
