金融界2024年6月3日消息，據國家知(zhi)識產權局公(gong)告，華電重工股份有(you)限公(gong)司申請一(yi)項(xiang)名為“一(yi)種燃燒(shao)褐煤(mei)火電機(ji)組基于熔鹽儲(chu)熱深度(du)調峰(feng)工藝系統(tong)”，公(gong)開號CN202410253964.0，申請日期為2024年3月。

專利摘(zhai)要顯示，本(ben)發(fa)明公開了一種燃(ran)燒褐煤(mei)火(huo)電(dian)(dian)機組基于熔(rong)(rong)(rong)鹽儲熱(re)(re)深度調峰工藝系(xi)(xi)統(tong)，包(bao)括：火(huo)電(dian)(dian)機組系(xi)(xi)統(tong)、熔(rong)(rong)(rong)鹽儲熱(re)(re)系(xi)(xi)統(tong)、熔(rong)(rong)(rong)鹽加(jia)(jia)(jia)熱(re)(re)系(xi)(xi)統(tong)、熔(rong)(rong)(rong)鹽放熱(re)(re)系(xi)(xi)統(tong)以及(ji)褐煤(mei)預干燥(zao)系(xi)(xi)統(tong)，所述火(huo)電(dian)(dian)機組系(xi)(xi)統(tong)燃(ran)燒褐煤(mei)進(jin)行發(fa)電(dian)(dian)，所述熔(rong)(rong)(rong)鹽儲熱(re)(re)系(xi)(xi)統(tong)用(yong)(yong)于冷、熱(re)(re)熔(rong)(rong)(rong)鹽的存儲，所述熔(rong)(rong)(rong)鹽加(jia)(jia)(jia)熱(re)(re)系(xi)(xi)統(tong)用(yong)(yong)于熔(rong)(rong)(rong)鹽加(jia)(jia)(jia)熱(re)(re)，熔(rong)(rong)(rong)鹽放熱(re)(re)系(xi)(xi)統(tong)利用(yong)(yong)熱(re)(re)熔(rong)(rong)(rong)鹽熱(re)(re)量將水加(jia)(jia)(jia)熱(re)(re)為過熱(re)(re)蒸汽，所述褐煤(mei)預干燥(zao)系(xi)(xi)統(tong)用(yong)(yong)于褐煤(mei)干燥(zao)。

本(ben)發(fa)明實現了火電機組(zu)基于熔鹽儲(chu)(chu)能的(de)深度(du)(du)調峰(feng)，通(tong)過熔鹽儲(chu)(chu)能系統儲(chu)(chu)存(cun)蒸汽的(de)顯熱(re)，實現火電機組(zu)鍋爐安全運行下增(zeng)強(qiang)機組(zu)深度(du)(du)調峰(feng)能力，乏汽對褐煤(mei)進(jin)行預干燥(zao)，不僅解決了褐煤(mei)干燥(zao)的(de)問題，而且提(ti)高了機組(zu)的(de)發(fa)電效率(lv)，提(ti)高了深度(du)(du)調峰(feng)的(de)能力以及系統的(de)儲(chu)(chu)熱(re)效率(lv)。
