太陽能(neng)發電(dian)是利用大規模陣(zhen)列鏡(jing)面收集太陽熱能(neng)，儲存(cun)在(zai)流體熔(rong)鹽(yan)中，通(tong)過(guo)管道送入蒸(zheng)汽發生器(qi)制造蒸(zheng)汽，結合(he)傳統汽輪發電(dian)機實現(xian)全天候發電(dian)。太陽能(neng)光熱發電(dian)技術相比硅晶(jing)光電轉(zhuan)換工藝成本大大降低，同(tong)時解(jie)決了以(yi)往新能(neng)源發電對風(feng)、光等條(tiao)件過度依賴(lai)的問題(ti)，在太陽落山后(hou)幾個小時仍然能(neng)夠帶動(dong)汽輪機發電，有(you)效緩(huan)解(jie)了電網壓力，是重要的前(qian)沿清潔能(neng)源技術。

  在甘肅省敦煌市向西(xi)約20千(qian)米(mi)處，被稱為(wei)“超級(ji)鏡(jing)(jing)子發(fa)電(dian)(dian)(dian)(dian)(dian)站”的(de)首(shou)航高(gao)科敦煌100兆瓦(wa)熔(rong)鹽(yan)塔式(shi)光熱(re)(re)電(dian)(dian)(dian)(dian)(dian)站在戈(ge)壁(bi)灘上閃耀（見圖3-2-11）。電(dian)(dian)(dian)(dian)(dian)站內約1.2萬面(mian)定日(ri)鏡(jing)(jing)以同心(xin)圓狀(zhuang)圍繞著260米(mi)高(gao)的(de)吸(xi)熱(re)(re)塔，鏡(jing)(jing)場總反射面(mian)積達(da)140多(duo)萬平方米(mi)，設計年發(fa)電(dian)(dian)(dian)(dian)(dian)量達(da)3.9億千(qian)瓦(wa)時，每年可(ke)減排(pai)二(er)氧化碳(tan)35萬噸(dun)，是我(wo)國目(mu)前(qian)建成(cheng)(cheng)規模最大、吸(xi)熱(re)(re)塔最高(gao)、可(ke)24小時連續發(fa)電(dian)(dian)(dian)(dian)(dian)的(de)100兆瓦(wa)級(ji)熔(rong)鹽(yan)塔式(shi)光熱(re)(re)電(dian)(dian)(dian)(dian)(dian)站。太陽能(neng)(neng)光熱(re)(re)發(fa)電(dian)(dian)(dian)(dian)(dian)被認為(wei)是具(ju)備成(cheng)(cheng)為(wei)基礎負荷電(dian)(dian)(dian)(dian)(dian)源潛力的(de)新(xin)興能(neng)(neng)源應(ying)用技術，敦煌100兆瓦(wa)熔(rong)鹽(yan)塔式(shi)光熱(re)(re)電(dian)(dian)(dian)(dian)(dian)站借助良好的(de)電(dian)(dian)(dian)(dian)(dian)網(wang)基礎優(you)勢(shi)，將新(xin)能(neng)(neng)源不斷輸往全國各地。

  塔式熔鹽光熱電站使用了大量的熔鹽，這些熔鹽具有一定的腐蝕性，而且還必須在500多攝氏度的高溫下運行25～30年，這要求與它們接觸的必須是高(gao)性能不(bu)銹鋼材料。久立集團研發的不(bu)銹鋼集熱管有效克服了熔鹽介質的腐蝕問題，同時配合光熱涂層使其能最大程度地吸收太陽能，又能防止熱能散失。經實踐證明，配合光熱涂層的久立集熱管完全滿足在高溫下長期連續工作的條件，大大提高了電站效率。目前久立集團生產的TP321、TP347、N06625等材料已經成功應用于迪拜、敦煌、南通、浙工大等多個光熱項目。
