摘　　要：针对某电厂4台锅炉风机原采用液力偶合器调速存在较大的转差损耗功率问题,提出采用变频调速以减少电耗。着重对锅炉风机变频调速改造的经济性进行了分析,阐述了改造的实施方案,总结了改造后的经济效果。Aiming at the problems of large slip consumption existing in the fluid speed-regulation coupler originally applied by fans of 4 power plant boilers,a proposal has been proposed by reducing energy consumption using variable-frequency control.With focus on an economic analysis of the variable-frequency retrofit,the specific retrofit scheme is described,while corresponding economic effects of the retrofit summarized.
