摘　　要：对无垢流化床换热器的应用进行了研究分析。针对现有设备的运行结构存在的问题，综合运用流化床、喷动床、快速床及沉降室的先进技术，在结构设计与运行计算上作了重大改进。研究表明，该结构可解决原有装置运行工况窄的缺点，上升管与下降管的合理布置以及凹形分布板、旋流板、导流筒等结构的首次应用有效地提高了装置的运行稳定性，扩大了运行工况范围，使之更适于工业生产的实际过程。The application of non-fouling nuidized bed heat exchanger was analyzed. Based on the advancedtechnology of fluidized bed, spouded bed, fast bed and settling theory, some new structures were medilied. Studiesshowed that, the optindZation design of the canier cireulating system, tbe solid-liquid separation structure, theconcave distribution and the application of diverting tube make the novel eqUipment work steady in a more wideoperating range.
