摘　　要：基于对220 t/h循环流化床锅炉内风帽的改进设计,搭建了风帽冷态水模型实验台,分别对此种新型风帽进行了阻力特性实验、均匀性实验、临界流化实验。实验结果表明:此种新型风帽安装之后,流化状态明显改善,阻力系数明显减小,从而证实了本风帽结构的合理性,为循环流化床锅炉风帽的优化研究提供了理论依据,为风帽设计开发提供了新的思路。Based on the improved design of the nozzle in the 220 t/h circulating fluidized bed, the cold state water model test bench for the nozzle was established in this study, and the experiment including resistance characteristic, uniformity and critical fluidization were carried out for this new type of nozzle.
