摘要
本文对目前国产的电厂锅炉离心风机的运行经济性同国外先进水平的同类风机进行了比较,通过分析存在差距的主要原因,提出可望在现有基础上提高运行效率平均在10%以上的改进建议。本文还通过借鉴当前国内外在研制风机及采用高效调节方式的新成果,提出几种有更高运行效率的电厂锅炉离心风机及调节装置的新方案和新设想。
Comparisons between the operation efficiency of the current domestic centrifugal fans on power stations and that of the advanced foreign centrifugal fans of the same type are made. Through the analysis of their differences in operation efficiency, suggestions for increasing the operation efficiency of domestic fans by 10% on average are presented. Moreover, by making use of the latest achievements in developing high efficient fans and regulating systems from home and abroad, several new patterns and designs of centrifugal fans and regulating devices with even higher operation efficiency are proposed.
