8月28日，晉煤集團成莊礦白(bai)沙風井的澡(zao)堂內，剛上井的礦工師(shi)傅(fu)們邊(bian)洗熱水澡(zao)，邊(bian)夸(kua)贊(zan)：“供熱水不(bu)用燒(shao)鍋爐，這低濃度瓦(wa)斯還(huan)真變成寶了！”
瓦(wa)斯作為(wei)煤炭開(kai)采過(guo)程中(zhong)的(de)(de)伴生(sheng)產物，甲烷濃(nong)(nong)(nong)度在30%以上的(de)(de)高濃(nong)(nong)(nong)度瓦(wa)斯已躋身工(gong)業燃(ran)料、化工(gong)原料之列(lie)，用(yong)于發電、民用(yong)等領域，成為(wei)清(qing)潔(jie)高效的(de)(de)新能源。但甲烷濃(nong)(nong)(nong)度6%-10%以下(xia)的(de)(de)低濃(nong)(nong)(nong)度瓦(wa)斯受國內外現有技術的(de)(de)應用(yong)限制(zhi)，尚未得到(dao)充分利用(yong)。
如(ru)今，晉(jin)煤集團銘石公司負責實施的煤礦低(di)濃度(du)瓦(wa)斯(si)直(zhi)燃(ran)制(zhi)熱一體化技術，在成(cheng)(cheng)莊礦白沙風井已成(cheng)(cheng)功替代燃(ran)氣(qi)(qi)鍋爐，每(mei)天供應60℃熱水約100噸(dun)，待項目(mu)全部建成(cheng)(cheng)后，預計每(mei)天可替換天然氣(qi)(qi)約2萬(wan)方。
經第三(san)方科技(ji)(ji)成果評(ping)價中(zhong)心邀請(qing)國(guo)內(nei)知(zhi)名院校行業專家(jia)鑒定(ding)，該(gai)項技(ji)(ji)術突破了《煤礦安(an)全(quan)規程》中(zhong)“抽采的瓦(wa)斯濃(nong)度低于30%時，不得(de)作為燃氣直(zhi)接燃燒”的技(ji)(ji)術限制，開(kai)辟了甲烷濃(nong)度6%-10%低濃(nong)度瓦(wa)斯利用的新途徑，填補了低濃(nong)度瓦(wa)斯直(zhi)燃利用的技(ji)(ji)術空白，達到國(guo)內(nei)領先水平。
據(ju)了解，晉(jin)煤(mei)(mei)集團在(zai)低(di)(di)濃(nong)(nong)度(du)(du)(du)瓦(wa)(wa)斯利(li)(li)用(yong)領域進行了多年實踐(jian)探索，建(jian)成(cheng)了甲烷(wan)濃(nong)(nong)度(du)(du)(du)10%-30%低(di)(di)濃(nong)(nong)度(du)(du)(du)瓦(wa)(wa)斯發(fa)電利(li)(li)用(yong)集群，持續開(kai)展(zhan)甲烷(wan)濃(nong)(nong)度(du)(du)(du)30%以(yi)下的(de)低(di)(di)濃(nong)(nong)度(du)(du)(du)瓦(wa)(wa)斯提純(chun)研究(jiu)，目前，每天(tian)可利(li)(li)用(yong)低(di)(di)濃(nong)(nong)度(du)(du)(du)瓦(wa)(wa)斯40萬方。當前，隨著甲烷(wan)濃(nong)(nong)度(du)(du)(du)6%-10%低(di)(di)濃(nong)(nong)度(du)(du)(du)瓦(wa)(wa)斯直(zhi)燃(ran)利(li)(li)用(yong)技(ji)術的(de)突破，晉(jin)煤(mei)(mei)集團將實現(xian)煤(mei)(mei)礦(kuang)瓦(wa)(wa)斯利(li)(li)用(yong)價(jia)值最大化，以(yi)實際行動聚焦“六新(xin)”，助推能源革(ge)命，為山西省乃至全國提供低(di)(di)濃(nong)(nong)度(du)(du)(du)瓦(wa)(wa)斯高(gao)效利(li)(li)用(yong)的(de)“晉(jin)煤(mei)(mei)經驗(yan)”。
