Technical and Economic Analysis of Draft Fan Lectotype for 1000 MW Thermal Power Units

Jun Xiao

Abstract

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.
