300MW发电机组中锅炉引风机进气箱的优化设计

Optimum-design for inlet-case of boiler fan used in 200MW generator units

在实验的基础上，分析了该机型存在的问题，并设计出一结构较为合理的进气箱模型。测试结果表明，其性能远优于现有产品的性能。

Based on experiments, problments of the customary one are analyzed and a more reasonable model is de- signed. Its performance is better than the costomary one.
