近日，河北華電石家莊熱電有限公司八期循環流化床鍋爐16臺風機電機變頻改造工作全部結束。改造后，每年可節電5334萬千瓦時，節約資金1866萬元，相當于每年節約標煤18669噸。
循環流(liu)化床鍋爐電(dian)(dian)(dian)(dian)耗比煤粉爐的(de)高，綜(zong)合(he)廠(chang)(chang)用(yong)電(dian)(dian)(dian)(dian)占(zhan)機組發電(dian)(dian)(dian)(dian)量的(de)15%，風機用(yong)電(dian)(dian)(dian)(dian)量占(zhan)機組廠(chang)(chang)用(yong)電(dian)(dian)(dian)(dian)量的(de)30%以(yi)上，電(dian)(dian)(dian)(dian)能損耗很大。為(wei)了節約(yue)能源，降低廠(chang)(chang)用(yong)電(dian)(dian)(dian)(dian)率，從2007年10月至今，河北華電(dian)(dian)(dian)(dian)石家(jia)莊熱電(dian)(dian)(dian)(dian)有限公司陸續投資2100萬元對16臺(tai)鍋爐引風機、一次風機電(dian)(dian)(dian)(dian)機進行了變頻(pin)改造(zao)完(wan)成后，該公司八期(qi)機組綜(zong)合(he)廠(chang)(chang)用(yong)電(dian)(dian)(dian)(dian)率下降了2.2％，全廠(chang)(chang)綜(zong)合(he)廠(chang)(chang)用(yong)電(dian)(dian)(dian)(dian)率下降了1.8％，取得了良好的(de)經濟效(xiao)益。
