摘要
将电机驱动引风机改为汽轮机驱动引风机后,不仅可以降低厂用电量,而且可有效提高引风机在低负荷工况运行的效率。针对火电站汽动引风机转速调节的运行特点,从引风机结构设计方面进行分析,介绍汽动引风机设计中的技术难点及解决方法。
Updating driven way induced draft fan by replacing motor with turbine,not only lowers the power consumption,but also increases induced draft fan operation efficiency under low load.According to the speed adjustment operation characteristics of turbine driven induced draft fan in thermal power plant,this paper introduces the design difficulties and its solutions from the aspect of analyzing structure designing of induced draft fan.
