本技(ji)術(shu)涉及一種煙氣熔鹽加(jia)熱器串聯蒸汽熔鹽加(jia)熱器的火電調(diao)峰系統。

背景技術：

1、在(zai)雙(shuang)碳政策下，國(guo)內能(neng)(neng)源市場發生(sheng)了翻天覆(fu)地的(de)變化，風(feng)電(dian)(dian)、光(guang)伏(fu)等(deng)非水可再生(sheng)能(neng)(neng)源大力發展，以實(shi)現碳中(zhong)和的(de)目(mu)標。但(dan)風(feng)電(dian)(dian)、光(guang)伏(fu)隨氣象條件變化的(de)波動性和不確定性對電(dian)(dian)網造(zao)成了一定程度的(de)沖(chong)擊，火力發電(dian)(dian)廠作為電(dian)(dian)網系(xi)(xi)統(tong)中(zhong)的(de)支撐和調節(jie)(jie)電(dian)(dian)源作用愈(yu)加(jia)明(ming)顯(xian)。但(dan)目(mu)前火電(dian)(dian)機組的(de)調節(jie)(jie)能(neng)(neng)力有限，一般最低負荷在(zai)40%以上，明(ming)顯(xian)無法(fa)滿足新型電(dian)(dian)力系(xi)(xi)統(tong)中(zhong)支撐和調節(jie)(jie)電(dian)(dian)源的(de)作用，在(zai)未來風(feng)電(dian)(dian)光(guang)伏(fu)大發時，無法(fa)進(jin)行(xing)深度降負荷，以滿足完全消納(na)新能(neng)(neng)源的(de)作用。

2、目前將熔(rong)(rong)鹽儲能應用于(yu)(yu)火電靈(ling)活(huo)性改造的(de)(de)(de)技術(shu)主(zhu)要(yao)有(you)兩(liang)種(zhong)，一是(shi)(shi)采(cai)用汽(qi)輪發電機組(zu)發出的(de)(de)(de)電進行電加熱(re)熔(rong)(rong)鹽儲能，二(er)是(shi)(shi)采(cai)用蒸(zheng)(zheng)(zheng)汽(qi)加熱(re)熔(rong)(rong)鹽儲能調峰。第一種(zhong)模式，電-熱(re)-電轉換效率較低(di)。第二(er)種(zhong)模式，由于(yu)(yu)蒸(zheng)(zheng)(zheng)汽(qi)的(de)(de)(de)能量主(zhu)要(yao)為汽(qi)化潛(qian)熱(re)，即便是(shi)(shi)亞臨界狀態下，蒸(zheng)(zheng)(zheng)汽(qi)飽(bao)和(he)點也僅在(zai)350℃左(zuo)右，這使得熔(rong)(rong)鹽加熱(re)溫度受到(dao)(dao)了(le)明顯的(de)(de)(de)限制，熔(rong)(rong)鹽在(zai)放(fang)熱(re)側(ce)產生的(de)(de)(de)蒸(zheng)(zheng)(zheng)汽(qi)溫度一般達不到(dao)(dao)400℃，和(he)加熱(re)熔(rong)(rong)鹽側(ce)的(de)(de)(de)蒸(zheng)(zheng)(zheng)汽(qi)溫度相比下降了(le)約有(you)150℃，蒸(zheng)(zheng)(zheng)汽(qi)品質有(you)明顯的(de)(de)(de)下降，無法回到(dao)(dao)主(zhu)蒸(zheng)(zheng)(zheng)汽(qi)管網，對熱(re)力(li)系統(tong)有(you)明顯的(de)(de)(de)影響。

8、本(ben)實用(yong)新型(xing)與(yu)現有技術相比，具有以下(xia)優(you)點和效果(guo)：

9、（1）通(tong)過能量(liang)的(de)(de)梯級加(jia)熱(re)，可將熔鹽(yan)溫度(du)提(ti)升(sheng)至(zhi)高溫，增加(jia)熔鹽(yan)使用(yong)(yong)(yong)溫域，減(jian)(jian)少熔鹽(yan)用(yong)(yong)(yong)量(liang)，減(jian)(jian)少一次(ci)性(xing)投(tou)資。通(tong)過本系統的(de)(de)設(she)計，熔鹽(yan)的(de)(de)使用(yong)(yong)(yong)溫度(du)可以從290℃至(zhi)565℃，增加(jia)了熔鹽(yan)使用(yong)(yong)(yong)溫域，在儲(chu)能容量(liang)不(bu)變的(de)(de)情況(kuang)下，大大減(jian)(jian)少了熔鹽(yan)用(yong)(yong)(yong)量(liang)，減(jian)(jian)少了相應熔鹽(yan)罐、熔鹽(yan)泵等設(she)備(bei)的(de)(de)投(tou)資。

10、（2）熔鹽汽(qi)水加(jia)熱器出口(kou)蒸汽(qi)溫(wen)度可提(ti)升至(zhi)主蒸汽(qi)溫(wen)度，其可送(song)至(zhi)原火(huo)電廠主蒸汽(qi)母管(guan)，增加(jia)系統發電效率。

11、（3）減少(shao)對原廠系(xi)統和主(zhu)(zhu)機(ji)的(de)(de)改(gai)造。在(zai)儲能(neng)時，加(jia)熱(re)蒸汽(qi)(qi)(qi)取自主(zhu)(zhu)蒸汽(qi)(qi)(qi)，和熔鹽換(huan)熱(re)的(de)(de)凝結水(shui)(shui)經增壓泵送(song)至(zhi)主(zhu)(zhu)給(gei)水(shui)(shui)系(xi)統。在(zai)釋能(neng)時，熔鹽汽(qi)(qi)(qi)水(shui)(shui)換(huan)熱(re)器產生主(zhu)(zhu)蒸汽(qi)(qi)(qi)，送(song)入汽(qi)(qi)(qi)輪(lun)機(ji)入口主(zhu)(zhu)汽(qi)(qi)(qi)管(guan)道。由于本系(xi)統送(song)入的(de)(de)蒸汽(qi)(qi)(qi)進入的(de)(de)是汽(qi)(qi)(qi)輪(lun)機(ji)的(de)(de)高壓缸進口，使得汽(qi)(qi)(qi)輪(lun)機(ji)的(de)(de)各個(ge)汽(qi)(qi)(qi)缸通流一致(zhi)性(xing)增加(jia)，對主(zhu)(zhu)機(ji)的(de)(de)影響(xiang)較小，在(zai)主(zhu)(zhu)機(ji)原設計超(chao)負荷范(fan)圍內(nei)，無需進行其他技術改(gai)造。
