摘　　要：针对循环流化床机组引风机运行过程中能耗大的问题,结合型号为Y4-2×60-14NO.33F的引风机具体运行参数,根据风机性能曲线、变工况管路特性曲线及风机调节方式,分析了风机选型偏大、管路特性曲线变化及风机变工况调节等因素下对风机效率的影响。通过引风机系统节能的分析,为引风机的选型及节能改造提供理论依据。Aimed to the problem of induced draft fan for circulating fluidized bed during the operation of large energy consumption,combined with model Y4-2 60-14 NO. 33 F specific operating parameters of the induced draft fan,according to the fan performance curve,variable condition pipeline characteristic curve and fan adjustment manner,under the influence of fan selection is too large,the pipeline characteristic curve and the fan variable conditions regulator and other factors on the efficiency of the fan. By analyzing the induced draft fan system energy saving,it Provides a theoretical basis for the selection and energy saving for induced draft fan.
