摘　　要：结合1000 MW火电机组引风机的选型,对动叶可调轴流式和静叶可调轴流式引风机进行了技术性能对比及综合经济比较。结论是两种引风机都是可行的,动叶可调轴流式风机运行经济性较好,而静叶可调轴流式风机初投资低,可靠性较高,耐磨性较好。With the draft fan lectotype for 1 000 MW thermal power units,the contrast of technical property and comparison of compositive economics is carried out for the axial draft fan of adjustable stationary blade and adjustable moving blade.The conclusion is that two type of draft fan are feasible.The operation economics of axial fan of adjustable moving blade is better,but for the axial fan of adjustable stationary blade,its invest is less,the reliability is higher,abrasion resistance is better.
