11月(yue)12日(ri)18時18分，中國華能集團(tuan)公司北京熱電(dian)(dian)(dian)廠(chang)三(san)期燃(ran)氣(qi)(qi)-蒸汽(qi)聯合(he)循環供熱機組一(yi)次性通過168小(xiao)時滿(man)負荷試運(yun)行，在北京正式供暖前(qian)實現(xian)投產發(fa)電(dian)(dian)(dian)目標。這也(ye)標志著首都四大燃(ran)氣(qi)(qi)熱電(dian)(dian)(dian)中心的收官之作——東南(nan)熱電(dian)(dian)(dian)中心建成投產。今冬，首都城六區將全部(bu)采用(yong)燃(ran)氣(qi)(qi)供暖。
168小(xiao)時(shi)滿(man)負(fu)荷(he)(he)試運行期間，機(ji)組平均負(fu)荷(he)(he)率達(da)98%以上，各項主要參(can)數達(da)到(dao)設計指(zhi)標(biao)。機(ji)組采用高效(xiao)低(di)(di)氮燃(ran)燒器，有效(xiao)降(jiang)低(di)(di)了脫硝入口(kou)的氮氧(yang)(yang)化(hua)物(wu)濃度，三(san)項污(wu)染物(wu)排(pai)(pai)放指(zhi)標(biao)為氮氧(yang)(yang)化(hua)物(wu)12.8毫克/立(li)方米(mi)(mi)、二氧(yang)(yang)化(hua)硫0.9毫克/立(li)方米(mi)(mi)，煙(yan)塵0.7毫克/立(li)方米(mi)(mi)，均低(di)(di)于北京(jing)市排(pai)(pai)放標(biao)準，達(da)到(dao)了超低(di)(di)排(pai)(pai)放水平。
據悉(xi)，北(bei)(bei)京熱(re)電(dian)(dian)(dian)廠(chang)一(yi)(yi)期(qi)(qi)燃煤發電(dian)(dian)(dian)機(ji)(ji)組已(yi)于2017年3月停備。二期(qi)(qi)工(gong)程(cheng)(cheng)(cheng)為建設一(yi)(yi)套(tao)F級“二拖一(yi)(yi)”燃氣-蒸汽聯合(he)循(xun)環供(gong)(gong)熱(re)機(ji)(ji)組，已(yi)于2011年底竣工(gong)，清(qing)潔(jie)供(gong)(gong)熱(re)面(mian)積約2000萬平方米。三期(qi)(qi)工(gong)程(cheng)(cheng)(cheng)是一(yi)(yi)期(qi)(qi)燃煤機(ji)(ji)組的替代工(gong)程(cheng)(cheng)(cheng)，建設一(yi)(yi)套(tao)F級“二拖一(yi)(yi)”燃氣-蒸汽聯合(he)循(xun)環供(gong)(gong)熱(re)機(ji)(ji)組，發電(dian)(dian)(dian)能力99.8萬千(qian)瓦(wa)，供(gong)(gong)熱(re)能力773兆瓦(wa)，供(gong)(gong)熱(re)面(mian)積約 1550萬平方米，是首都電(dian)(dian)(dian)網百萬千(qian)瓦(wa)級節能環保綠色電(dian)(dian)(dian)站項目。三期(qi)(qi)工(gong)程(cheng)(cheng)(cheng)投產后，北(bei)(bei)京熱(re)電(dian)(dian)(dian)廠(chang)全(quan)面(mian)實(shi)現清(qing)潔(jie)發電(dian)(dian)(dian)、供(gong)(gong)熱(re)。
