电站煤粉锅炉风机节能改造策略及经济性分析

Strategy and Economic Analysis on Energy-saving Retrofit of Pulverized-coal Boilers Fans

通过对多起风机节能改造案例研究,从风机节能改造安全性和经济性入手,重点探讨了电站煤粉锅炉风机设计容量偏大、液耦调节传动效率低、静调轴流风机效率低、风机系统管路阻力偏大等方面的节能改造策略及注意事项,为火力发电机组经济性提升提供参考。

Abstracts： Based on the study of the energy-saving retrofit cases, this paper starts from the safety and economy of the energy-saving retrofit with fan, focuses on energy saving strategy and the matters needing attention about the problems that design capacity of fans are too large, the transmission efficiency of fluid coupling regulating is low, static adjustable axial-flow fan efficiency is low, the resistance of pipeline system is too large, provide a reference for thermal power generating units to improve the economy of the fans.
