用(yong)(yong)太陽能(neng)(neng)提供熱(re)源，用(yong)(yong)熔鹽吸收熱(re)量(liang)，轉(zhuan)換(huan)成(cheng)(cheng)蒸汽發電(dian)(dian)，夜(ye)間(jian)或陰雨天也能(neng)(neng)持續(xu)發電(dian)(dian)。近日(ri)，藍星(北(bei)京)化(hua)工機械(xie)有限公司(以下簡稱“藍星北(bei)化(hua)機”)開(kai)發的光(guang)(guang)熱(re)發電(dian)(dian)儲能(neng)(neng)技術繼成(cheng)(cheng)功(gong)應用(yong)(yong)于青(qing)海德令(ling)哈10MW光(guang)(guang)熱(re)發電(dian)(dian)站(zhan)項(xiang)目(mu)后，又成(cheng)(cheng)功(gong)應用(yong)(yong)于青(qing)海中控德令(ling)哈50MW光(guang)(guang)熱(re)發電(dian)(dian)站(zhan)項(xiang)目(mu)，實現了(le)科技成(cheng)(cheng)果(guo)產業(ye)轉(zhuan)化(hua)。

光(guang)(guang)(guang)熱(re)發電(dian)(dian)是繼風電(dian)(dian)、核能(neng)(neng)(neng)、光(guang)(guang)(guang)伏(fu)發電(dian)(dian)之后在(zai)(zai)全(quan)球范圍內發展迅(xun)速的新能(neng)(neng)(neng)源(yuan)(yuan)技術，全(quan)生命周期碳(tan)排放(fang)量低于(yu)現有各種能(neng)(neng)(neng)源(yuan)(yuan)，被認(ren)為是最清潔(jie)的能(neng)(neng)(neng)源(yuan)(yuan)利用形式。藍星北化機開發的熔(rong)(rong)鹽(yan)儲熱(re)系統，是光(guang)(guang)(guang)熱(re)發電(dian)(dian)站的核心組成部分之一，熔(rong)(rong)鹽(yan)儲熱(re)系統使(shi)電(dian)(dian)廠能(neng)(neng)(neng)不(bu)受環境(jing)影響持續穩定(ding)輸出電(dian)(dian)力，克服了新能(neng)(neng)(neng)源(yuan)(yuan)中普(pu)遍存在(zai)(zai)的“棄(qi)風”“棄(qi)光(guang)(guang)(guang)”問題。

“該技(ji)術(shu)白天利用太陽(yang)能(neng)將(jiang)流過吸熱器的熔(rong)鹽(yan)加熱至高(gao)(gao)(gao)溫(wen)(wen)狀態，一(yi)部(bu)分通過換(huan)熱器產生蒸(zheng)汽直接發電(dian)，一(yi)部(bu)分在(zai)高(gao)(gao)(gao)溫(wen)(wen)熔(rong)鹽(yan)罐(guan)中儲存(cun)起(qi)來。”藍(lan)星北化機相關(guan)負責人說，即便(bian)是在(zai)夜間(jian)或陰雨天，儲存(cun)的能(neng)量通過換(huan)熱器產生高(gao)(gao)(gao)溫(wen)(wen)高(gao)(gao)(gao)壓蒸(zheng)汽發電(dian)，溫(wen)(wen)度降低(di)的熔(rong)鹽(yan)進入(ru)(ru)低(di)溫(wen)(wen)罐(guan)，準備進入(ru)(ru)下一(yi)個(ge)循環(huan)。該技(ji)術(shu)成功(gong)解決了(le)熔(rong)鹽(yan)介質高(gao)(gao)(gao)溫(wen)(wen)、腐蝕性(xing)強、基礎散熱、熱變形及(ji)保溫(wen)(wen)等(deng)難題。熔(rong)鹽(yan)蓄熱儲能(neng)技(ji)術(shu)是使太陽(yang)能(neng)光熱發電(dian)具備調峰能(neng)力新型基礎電(dian)源的關(guan)鍵技(ji)術(shu)，還(huan)可用于供(gong)暖供(gong)氣領域。

藍星北(bei)化機繼把該技(ji)術(shu)成功(gong)應用于(yu)青海德(de)(de)令(ling)哈10MW光(guang)熱(re)發(fa)電站(zhan)(zhan)項(xiang)目后，又成功(gong)應用于(yu)青海中控德(de)(de)令(ling)哈50MW光(guang)熱(re)發(fa)電站(zhan)(zhan)項(xiang)目，該項(xiang)目的成功(gong)并網(wang)發(fa)電穩定運行帶給了業(ye)主(zhu)優(you)秀的經營(ying)業(ye)績與實質的碳匯(hui)交易效果。50MW塔式光(guang)熱(re)發(fa)電熔鹽(yan)蓄熱(re)儲能系(xi)統及裝(zhuang)備項(xiang)目還得到了北(bei)京市節(jie)能技(ji)術(shu)產品(pin)評審(shen)專家的認可，列(lie)入(ru)北(bei)京市節(jie)能技(ji)術(shu)產品(pin)推薦目錄。
