“白天(tian)用天(tian)然氣供(gong)熱，晚上(shang)用電(dian)供(gong)暖，不僅節省了天(tian)然氣，而且供(gong)暖溫(wen)度絲毫沒有(you)‘打(da)折’。”1月(yue)4日，家住新(xin)疆烏魯(lu)木齊博洋雅居(ju)小(xiao)區的(de)艾尼(ni)瓦爾·阿布(bu)都瓦依(yi)提看了一(yi)眼室內溫(wen)度計的(de)示(shi)數——20攝氏度。他高(gao)興地說，自從小(xiao)區采用“氣電(dian)互補”模式供(gong)熱后，家里的(de)溫(wen)度一(yi)直保持在20攝氏度以上(shang)。
在(zai)國家電(dian)網公司(si)的(de)統一部署下，各(ge)地(di)加快了電(dian)能替代(dai)的(de)步伐，新(xin)疆烏魯木齊(qi)供(gong)(gong)電(dian)公司(si)充(chong)分利用當地(di)的(de)有效(xiao)資源，因地(di)制(zhi)宜制(zhi)定推廣“以(yi)電(dian)代(dai)煤(mei)、以(yi)電(dian)代(dai)油、以(yi)電(dian)帶氣”的(de)電(dian)能替代(dai)項目。目前，新(xin)疆試點建設(she)“氣電(dian)互補”供(gong)(gong)暖新(xin)模式，已建成(cheng)供(gong)(gong)熱面積16700平方米的(de)“試驗田”。
自烏(wu)(wu)魯木(mu)(mu)齊(qi)市“煤改氣(qi)(qi)(qi)”工程實施以來，天然(ran)氣(qi)(qi)(qi)已(yi)(yi)經成為烏(wu)(wu)魯木(mu)(mu)齊(qi)供(gong)(gong)(gong)熱(re)的(de)(de)主要(yao)能源。然(ran)而(er)，烏(wu)(wu)魯木(mu)(mu)齊(qi)天然(ran)氣(qi)(qi)(qi)年度(du)需求量從(cong)2010年的(de)(de)8.4億立方米(mi)急劇上升至2014年的(de)(de)29.4億立方米(mi)，特(te)別是(shi)冬(dong)季(ji)用氣(qi)(qi)(qi)高(gao)峰，日用氣(qi)(qi)(qi)量已(yi)(yi)突破2500萬(wan)立方米(mi)，缺口(kou)日益顯現。“氣(qi)(qi)(qi)電(dian)互補”供(gong)(gong)(gong)暖(nuan)(nuan)模(mo)式(shi)直(zhi)接利用現有熱(re)力管(guan)網實現電(dian)采暖(nuan)(nuan)，在換熱(re)站(zhan)(zhan)內的(de)(de)集(ji)(ji)中(zhong)供(gong)(gong)(gong)暖(nuan)(nuan)換熱(re)站(zhan)(zhan)支線上并聯一(yi)個(ge)電(dian)鍋(guo)爐作為集(ji)(ji)中(zhong)供(gong)(gong)(gong)暖(nuan)(nuan)的(de)(de)補充(chong)熱(re)源。烏(wu)(wu)魯木(mu)(mu)齊(qi)供(gong)(gong)(gong)電(dian)公(gong)司營銷(xiao)部(bu)負責人說，這(zhe)種供(gong)(gong)(gong)暖(nuan)(nuan)模(mo)式(shi)投(tou)資較(jiao)小，運行穩定(ding)，后期維護成本較(jiao)低，安全無污染。尤其在冬(dong)季(ji)寒冷、暴(bao)雪等極端天氣(qi)(qi)(qi)情況(kuang)下，當天然(ran)氣(qi)(qi)(qi)緊缺或集(ji)(ji)中(zhong)供(gong)(gong)(gong)暖(nuan)(nuan)因系統(tong)衰減達不到(dao)(dao)供(gong)(gong)(gong)暖(nuan)(nuan)要(yao)求時，電(dian)鍋(guo)爐就會補充(chong)供(gong)(gong)(gong)熱(re)，確(que)保(bao)供(gong)(gong)(gong)暖(nuan)(nuan)溫度(du)達到(dao)(dao)一(yi)定(ding)要(yao)求，保(bao)障居(ju)民(min)供(gong)(gong)(gong)暖(nuan)(nuan)不受外界氣(qi)(qi)(qi)候環境的(de)(de)影響(xiang)。
“電(dian)鍋爐(lu)采(cai)(cai)用(yong)全(quan)自動控制(zhi)，在(zai)凌晨零時至早8時用(yong)電(dian)低峰期(qi)采(cai)(cai)用(yong)電(dian)供(gong)暖(nuan)(nuan)，電(dian)鍋爐(lu)運行8小時，核算下來消耗電(dian)量為5760千瓦時，相當于節省天然(ran)氣(qi)614立方米(mi)。”新(xin)疆維(wei)泰熱力股(gu)份有限公司負責人說，供(gong)熱企(qi)業與供(gong)電(dian)公司合作推廣(guang)的“氣(qi)電(dian)互補”供(gong)暖(nuan)(nuan)模式(shi)，不(bu)但緩解了供(gong)暖(nuan)(nuan)能源緊張(zhang)的狀況(kuang)，而(er)且既(ji)經濟又環保。
“氣電互補(bu)”供暖(nuan)模式目(mu)前在(zai)(zai)烏(wu)(wu)(wu)魯(lu)木(mu)齊(qi)市高鐵片區(qu)(qu)(qu)開(kai)始試(shi)點(dian)推廣，試(shi)點(dian)區(qu)(qu)(qu)建在(zai)(zai)烏(wu)(wu)(wu)魯(lu)木(mu)齊(qi)經(jing)濟技術開(kai)發(fa)區(qu)(qu)(qu)（頭屯河區(qu)(qu)(qu)）新疆維泰熱(re)力換(huan)熱(re)站，1400千瓦(wa)的電鍋爐已建成并投入運行，為博洋雅居(ju)小區(qu)(qu)(qu)144戶居(ju)民提供供暖(nuan)服務，今年(nian)還將在(zai)(zai)烏(wu)(wu)(wu)魯(lu)木(mu)齊(qi)軟件園建設10萬平(ping)方米的電熱(re)供暖(nuan)區(qu)(qu)(qu)。
烏魯木(mu)齊市“氣電互(hu)補”項(xiang)目是新(xin)疆電能替代(dai)試點(dian)，冬季采(cai)暖期過后(hou)，烏魯木(mu)齊供電公司將完成(cheng)整個采(cai)暖期的數據(ju)(ju)采(cai)集，開展(zhan)數據(ju)(ju)分析(xi)，根據(ju)(ju)試點(dian)完成(cheng)情況進行推廣(guang)。
除積(ji)極探索開展“氣電互補”供(gong)(gong)暖模式外，烏(wu)魯木齊供(gong)(gong)電公司還大力推(tui)廣熱電聯產(chan)、地源熱泵、電采暖等(deng)供(gong)(gong)熱方式。目(mu)前，烏(wu)魯木齊已形成以天(tian)然氣供(gong)(gong)熱為主、清潔能源供(gong)(gong)熱為輔的多元(yuan)供(gong)(gong)熱格(ge)局。
未(wei)來，隨著光(guang)伏發電(dian)(dian)、風電(dian)(dian)等新(xin)能源(yuan)大規模(mo)開發以及超高壓電(dian)(dian)網大規模(mo)建設，新(xin)疆(jiang)北部、西(xi)部能源(yuan)基(ji)地向(xiang)烏(wu)魯(lu)木齊電(dian)(dian)網輸送電(dian)(dian)力能力將進一步加強，可(ke)大幅提高烏(wu)魯(lu)木齊電(dian)(dian)網的(de)受電(dian)(dian)能力，為清潔(jie)供(gong)暖提供(gong)充足的(de)電(dian)(dian)能保障(zhang)。
