日前，江蘇華電揚州發電有限公司6號機組脫硝改造工程氨區首次進氨順利完成。目前氨區儲存液氨25噸，脫硝氨區制氨和反應器的噴氨調試工作全面展開，為力爭5月底完成6號機組脫硝改造工程168小時試運行創造了條件。
6號(hao)機組(zu)(zu)(zu)脫(tuo)硝改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)程(cheng)是該(gai)公(gong)司首(shou)臺330MW機組(zu)(zu)(zu)安裝脫(tuo)硝系統(tong)，脫(tuo)硝工(gong)(gong)(gong)程(cheng)采用SCR法(fa)（選(xuan)擇性催(cui)化還原法(fa)）進(jin)行(xing)脫(tuo)硝，氨(an)氣(qi)的(de)制備采用液氨(an)法(fa)進(jin)行(xing)，設計脫(tuo)硝效(xiao)率75%。針對企業所處地理(li)(li)位置特殊，對環保(bao)工(gong)(gong)(gong)作的(de)高要(yao)求(qiu)，以及(ji)老(lao)機組(zu)(zu)(zu)脫(tuo)硝改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)程(cheng)地下管(guan)網設施(shi)復雜、施(shi)工(gong)(gong)(gong)難度大、首(shou)次改(gai)(gai)(gai)造(zao)無經驗可鑒等困難，為確保(bao)高質量完成脫(tuo)硝改(gai)(gai)(gai)造(zao)任務。該(gai)公(gong)司高起點定位籌備，做實(shi)改(gai)(gai)(gai)造(zao)前期各項準(zhun)備，狠抓項目立(li)項、可研論證、過程(cheng)管(guan)理(li)(li)。 通(tong)過縱向對比、橫向分(fen)析，多次召開(kai)(kai)專(zhuan)題(ti)會議討論研究，對項目方案進(jin)行(xing)反復優化論證，努力為創塑精(jing)品工(gong)(gong)(gong)程(cheng)打下基礎。抓住去年底(di)6號(hao)機組(zu)(zu)(zu)機組(zu)(zu)(zu)整(zheng)體優化改(gai)(gai)(gai)造(zao)的(de)有(you)利時機，實(shi)施(shi)機組(zu)(zu)(zu)脫(tuo)硝改(gai)(gai)(gai)造(zao)。脫(tuo)硝改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)程(cheng)開(kai)(kai)工(gong)(gong)(gong)后，該(gai)公(gong)司加強與施(shi)工(gong)(gong)(gong)、監(jian)理(li)(li)單位溝通(tong)協調，提(ti)前介入施(shi)工(gong)(gong)(gong)過程(cheng)的(de)安全、質量、進(jin)度把關(guan)，多次組(zu)(zu)(zu)織(zhi)(zhi)專(zhuan)項檢查，狠抓存在問題(ti)的(de)督查整(zheng)改(gai)(gai)(gai)，有(you)效(xiao)地保(bao)證了(le)脫(tuo)硝改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)程(cheng)穩(wen)步(bu)推進(jin)。同時，該(gai)公(gong)司積極(ji)做好接好、管(guan)好脫(tuo)硝準(zhun)備工(gong)(gong)(gong)作，及(ji)時制訂落(luo)實(shi)相關(guan)管(guan)理(li)(li)制度，先(xian)后組(zu)(zu)(zu)織(zhi)(zhi)實(shi)施(shi)了(le)脫(tuo)硝工(gong)(gong)(gong)程(cheng)氨(an)區(qu)消(xiao)防(fang)知識培訓、脫(tuo)硝氨(an)區(qu)安全管(guan)理(li)(li)、脫(tuo)硝技術等一系列專(zhuan)題(ti)培訓、講座(zuo)，有(you)效(xiao)地為脫(tuo)銷改(gai)(gai)(gai)造(zao)工(gong)(gong)(gong)程(cheng)設備分(fen)步(bu)調試(shi)，現場安全管(guan)理(li)(li)提(ti)供了(le)安全技術支撐(cheng)。
