低谷電鎂磚蓄熱蒸汽鍋爐運行原理及成本解析

什么叫低谷電鎂磚蓄熱蒸汽鍋爐？
目前電(dian)(dian)(dian)力管理(li)部門將全天用(yong)(yong)(yong)電(dian)(dian)(dian)分為4個時(shi)段(duan)(duan)；尖峰(feng)用(yong)(yong)(yong)電(dian)(dian)(dian)、峰(feng)用(yong)(yong)(yong)電(dian)(dian)(dian)、谷(gu)用(yong)(yong)(yong)電(dian)(dian)(dian)、平用(yong)(yong)(yong)電(dian)(dian)(dian)。尖峰(feng)用(yong)(yong)(yong)電(dian)(dian)(dian)是指在(zai)用(yong)(yong)(yong)電(dian)(dian)(dian)量集中的(de)時(shi)間(jian)(jian)(jian)段(duan)(duan)；峰(feng)用(yong)(yong)(yong)電(dian)(dian)(dian)是指在(zai)用(yong)(yong)(yong)電(dian)(dian)(dian)量相對集中的(de)時(shi)間(jian)(jian)(jian)段(duan)(duan)；谷(gu)用(yong)(yong)(yong)電(dian)(dian)(dian)是指在(zai)用(yong)(yong)(yong)電(dian)(dian)(dian)量相對較少的(de)時(shi)間(jian)(jian)(jian)段(duan)(duan)；平用(yong)(yong)(yong)電(dian)(dian)(dian)為剩余時(shi)間(jian)(jian)(jian)段(duan)(duan)。具體(ti)每個時(shi)間(jian)(jian)(jian)段(duan)(duan)的(de)界定，各地(di)政策均有不同。

對于(yu)終(zhong)端用電(dian)單(dan)位來講，使用低谷電(dian)可(ke)以降低企事(shi)業單(dan)位的運(yun)行成本，同時因為(wei)使用清潔能(neng)源(yuan)，可(ke)以避免一系列(lie)的環保(bao)問題。

基于這(zhe)樣的環境，我們研發設計生產了低(di)谷電蓄熱鍋爐，主要(yao)原理是，在夜(ye)間供(gong)電低(di)谷時(shi)(shi)段（一般(ban)為22點至7點，每度(du)電一般(ban)在0.30元-0.60元之間，根據各(ge)地政策略(lve)有(you)差異(yi)），利用夜(ye)間廉價(jia)的低(di)谷電，將固體合金蓄熱介質加熱到預定溫度(du)儲存(cun)熱量(liang)，然后通過(guo)自控裝置，將低(di)谷電時(shi)(shi)段儲存(cun)的熱量(liang)在非(fei)低(di)谷電時(shi)(shi)段或者全天24小時(shi)(shi)按需要(yao)釋放，從(cong)而實現均衡供(gong)熱需求(qiu)。

金喆新能源設計生產的低谷電蓄熱蒸汽鍋爐，又因為其蓄熱介質的基礎材料為鎂，又常被稱為鎂磚蓄熱蒸汽鍋爐、固體蓄熱蒸汽鍋爐、固體電蓄熱蒸汽機組。

低谷電蓄熱蒸汽鍋爐的運行原理解析
利(li)用谷(gu)電時段價(jia)格低廉的電能將固體蓄熱體加熱到超高(gao)溫(wen)(wen)(wen)，工作時間(jian)段啟動高(gao)溫(wen)(wen)(wen)循環風(feng)機(ji)將高(gao)溫(wen)(wen)(wen)熱風(feng)送(song)入蒸(zheng)汽(qi)(qi)發(fa)生(sheng)器(qi)，在蒸(zheng)汽(qi)(qi)發(fa)生(sheng)器(qi)內加熱高(gao)壓柱塞泵加壓送(song)入的軟(ruan)化(hua)水，經換熱產生(sheng)高(gao)溫(wen)(wen)(wen)高(gao)壓蒸(zheng)汽(qi)(qi)，本(ben)機(ji)組可利(li)用天(tian)然氣燃(ran)燒補熱，蒸(zheng)汽(qi)(qi)穩定。

低谷電蓄熱蒸汽鍋爐的運行成本解析
因為鍋爐主要耗電時段是電價低廉的低谷電時段，所以，運行成本僅為傳統電蒸汽發生器的1/3-1/2，并且占地面積小50%以上，是非常省錢、新型高效的電蒸汽鍋爐（電蒸汽機組）。
電蒸汽(qi)鍋爐噸蒸汽(qi)成(cheng)本(ben)(ben)超過(guo)500元(yuan)，天然氣超過(guo)300元(yuan)，利用谷電蓄熱(re)產(chan)蒸汽(qi)，噸蒸汽(qi)成(cheng)本(ben)(ben)在210元(yuan)左右(you)，是目前除了燃煤機組或者電廠余熱(re)外價格較低的清潔能源供熱(re)方式(shi)。
