世界首例:
3月(yue)11日(ri)上午,哈(ha)電集團(tuan)(tuan)電機公司為陜西國華錦(jin)界(jie)電廠三期擴建工程制(zhi)造的首(shou)臺全(quan)空冷發(fa)電機組定(ding)子,在錦(jin)界(jie)電廠順(shun)利完(wan)成吊裝作業。作為“世界(jie)首(shou)例”高位布置發(fa)電機定(ding)子設(she)備,此次吊裝作業項目節點的順(shun)利完(wan)成標志著哈(ha)電集團(tuan)(tuan)等“中(zhong)國力量”再次奪得世界(jie)電力行(xing)業的又(you)一個“第一”!
據了解,錦界電(dian)(dian)廠發電(dian)(dian)機(ji)組(zu)定(ding)子重290噸(dun),起(qi)吊(diao)高(gao)(gao)度達到(dao)65米(mi),相(xiang)(xiang)當(dang)于上(shang)了22層樓,與常(chang)規發電(dian)(dian)機(ji)布置平臺(tai)上(shang)僅起(qi)吊(diao)13.7米(mi)的高(gao)(gao)度相(xiang)(xiang)比(bi),該工程(cheng)發電(dian)(dian)機(ji)設備高(gao)(gao)位布置平臺(tai)可謂高(gao)(gao)入(ru)“云端(duan)”。作為(wei)世(shi)界最高(gao)(gao)布置平臺(tai),其具有縮短(duan)管道(dao)長度、降(jiang)低供電(dian)(dian)煤耗、提(ti)高(gao)(gao)機(ji)組(zu)熱效率等優點(dian)。
2016年(nian)12月,哈電集(ji)團電機公司中標錦界電廠項目(mu)合同(tong)(tong)后,公司設計人(ren)員(yuan)深入研(yan)(yan)究高位(wei)布置汽(qi)輪發電機組運(yun)行(xing)(xing)(xing)特點(dian)及需求(qiu),并結(jie)合常規(gui)電廠運(yun)行(xing)(xing)(xing)經驗對原(yuan)有(you)設計及工藝進行(xing)(xing)(xing)優(you)化,采用全空冷(leng)結(jie)構和全封(feng)閉技術(shu),解決了污(wu)物和潮(chao)濕氣(qi)體易(yi)于進入通風(feng)冷(leng)卻(que)系統等(deng)問題(ti)。同(tong)(tong)時,電機公司還完成了“新型660MW發電機定(ding)子(zi)機座(zuo)組焊方法”“ 新型660MW發電機定(ding)子(zi)機座(zuo)機械(xie)加工方法”等(deng)課題(ti)研(yan)(yan)究,并取(qu)得數項專利,為該項目(mu)汽(qi)輪發電機安全穩定(ding)運(yun)行(xing)(xing)(xing)提(ti)供了技術(shu)保障。
國(guo)華錦界電(dian)(dian)(dian)廠地處陜(shan)(shan)西省神木(mu)市,其煤電(dian)(dian)(dian)一體化項(xiang)(xiang)目(mu)是(shi)國(guo)家(jia)“西電(dian)(dian)(dian)東送(song)”的示(shi)范(fan)項(xiang)(xiang)目(mu),同時也是(shi)國(guo)家(jia)大(da)氣(qi)污(wu)染防治計(ji)劃重點(dian)建(jian)設(she)(she)項(xiang)(xiang)目(mu)、陜(shan)(shan)西省重點(dian)建(jian)設(she)(she)項(xiang)(xiang)目(mu)。該(gai)電(dian)(dian)(dian)廠三期擴建(jian)工程計(ji)劃建(jian)設(she)(she)2臺單機容(rong)量為660兆瓦的超超臨界發(fa)(fa)電(dian)(dian)(dian)機組,兩臺機組均(jun)由哈(ha)電(dian)(dian)(dian)集(ji)團(tuan)電(dian)(dian)(dian)機公司制造,已分別于(yu)2019年(nian)11月(yue)和(he)12月(yue)發(fa)(fa)運,并于(yu)2020年(nian)3月(yue)陸(lu)續運抵現場。
