據東(dong)(dong)方(fang)(fang)(fang)(fang)電(dian)氣集(ji)團東(dong)(dong)方(fang)(fang)(fang)(fang)鍋爐(lu)股份有限(xian)(xian)公司（簡稱(cheng)(cheng)：東(dong)(dong)方(fang)(fang)(fang)(fang)鍋爐(lu)）消息，6月20日，東(dong)(dong)方(fang)(fang)(fang)(fang)鍋爐(lu)承(cheng)接的桐(tong)鄉聚能啟泰儲(chu)能科技(ji)有限(xian)(xian)公司的多(duo)能耦(ou)合智慧低(di)碳(tan)供能項(xiang)目（簡稱(cheng)(cheng)“桐(tong)鄉項(xiang)目”）核心(xin)關鍵設備熔鹽蒸汽發生(sheng)器(qi)、再熱器(qi)發運，標志著東(dong)(dong)方(fang)(fang)(fang)(fang)鍋爐(lu)首個基(ji)于(yu)熔鹽儲(chu)熱技(ji)術的綜(zong)合能源方(fang)(fang)(fang)(fang)案向投運目標邁出了堅實的一步。

項目投(tou)用后，每年可消納谷電2.362億度，對外供熱25.4萬(wan)(wan)噸(dun)，上網供電2245萬(wan)(wan)千瓦時，二氧化(hua)碳減排3.3萬(wan)(wan)噸(dun)，相當于節約標(biao)準煤(mei)1.7萬(wan)(wan)噸(dun)。

據此前相關報道，該(gai)項目(mu)(mu)擬在浙(zhe)(zhe)江(jiang)省桐鄉(xiang)市新(xin)建1套有效存(cun)儲(chu)熱量為343MWht的熔(rong)鹽(yan)儲(chu)能系(xi)統及1×6.5MW發電(dian)(dian)(dian)機及配套管網、接入等輔(fu)助設(she)施。谷電(dian)(dian)(dian)階(jie)(jie)段本項目(mu)(mu)通過熔(rong)鹽(yan)電(dian)(dian)(dian)加(jia)熱系(xi)統進行(xing)儲(chu)能，儲(chu)能用電(dian)(dian)(dian)量約70MW；峰電(dian)(dian)(dian)階(jie)(jie)段由熔(rong)鹽(yan)換熱系(xi)統產生高(gao)溫高(gao)壓(ya)的蒸汽進入汽輪(lun)機發電(dian)(dian)(dian)。本期工程建設(she)完(wan)成后，在提供園區用綠色蒸汽的同時(shi)，熱電(dian)(dian)(dian)廠(chang)可以外(wai)送(song)的電(dian)(dian)(dian)量約為0.2245×108kWh/年。2023年6月2日(ri)，中國聯合(he)工程有限(xian)(xian)公(gong)(gong)司(si)【聯合(he)體：物產中大（浙(zhe)(zhe)江(jiang)）儲(chu)能科技(ji)有限(xian)(xian)公(gong)(gong)司(si)、浙(zhe)(zhe)江(jiang)啟(qi)明電(dian)(dian)(dian)力集(ji)團有限(xian)(xian)公(gong)(gong)司(si)】以2.336億元價格中標(biao)該(gai)項目(mu)(mu)EPC。

東(dong)方鍋爐多部門通(tong)力合作(zuo)，憑借通(tong)過仿真模擬保障設備性能、方案優化確(que)保儲罐溫降以及定制化滿(man)足用戶特殊需求等手段(duan)，最(zui)終獲得業主(zhu)認(ren)可，成功斬獲浙(zhe)江省2023年“尖兵”研發攻關項(xiang)(xiang)目，即(ji)桐鄉項(xiang)(xiang)目。

該項目通過“谷(gu)電(dian)熔(rong)鹽儲能(neng)，峰(feng)(feng)電(dian)熱(re)電(dian)聯供”的循(xun)環模式，實現綠電(dian)消(xiao)納(na)，清潔供熱(re)。通俗來說，就是利用(yong)“谷(gu)電(dian)”時段，吸納(na)同時段“谷(gu)電(dian)”“綠電(dian)”能(neng)量，用(yong)于加熱(re)熔(rong)鹽儲能(neng)，在電(dian)網“峰(feng)(feng)電(dian)”和“尖峰(feng)(feng)電(dian)”時段頂峰(feng)(feng)發電(dian)，供應整(zheng)個工業園區全天(tian)用(yong)熱(re)，進一步優(you)化能(neng)源(yuan)消(xiao)費結構。
