摘要

通过对液力耦合调速器、变频调速器和永磁驱动调速器优缺点的比较

决定采用永磁驱动调速技术对某电厂锅炉引风机进行改造

并对改造后的经济效益和安全性能进行了分析。改造后

机组运行振幅下降83%

噪音降幅35%

机组每年可节省费用60.9万元

不到2年就可收回投资

风机经济性、安全可靠性显著提高。

Abstract

By analyzing the advantages and disadvantages of the variable-frequence governor

hydraulic coupling governor and the permanent magnet drive speeder

the permanent magnet speed control technology was applied to conduct retrofit for induced draft(ID)fans in boiler of a power plant.After the transformation

the unit can save 609 000yuan per year

meaning the investment can be recovered within less than two years;the vibration amplitude of the air fan decreased by 83%

and the noise dropped by 35%.
