1、1電力建設施工及驗收技術規(guī)范電力建設施工及驗收技術規(guī)范鍋爐機組篇TheCodeofErectionAcceptanceofElectricPowerConstructionSectionofSteamBoilerSetDLT5047—95主編部門：電力工業(yè)部電力建設技術經(jīng)濟咨詢中心中國電力企業(yè)聯(lián)合會標準化部批準部門：中華人民共和國電力工業(yè)部前言《電力建設施工及驗收技術規(guī)范(鍋爐機組篇)》(SDJ245—88)自發(fā)布實施以來，對電力工業(yè)建

2、設和電站鍋爐施工質(zhì)量的提高都起到了積極的促進作用。隨著我國社會主義市場經(jīng)濟的迅猛發(fā)展，電力工業(yè)的發(fā)展和發(fā)電質(zhì)量的提高是社會經(jīng)濟發(fā)展的基本保證。為了確保對火力發(fā)電廠“安全、經(jīng)濟、穩(wěn)發(fā)、滿發(fā)”運行的要求，適應大機組、新設備施工的需要，我們組織有關人員對原規(guī)范進行了修改和補充，作了較大的改動，并經(jīng)三次組織討論和審定。本規(guī)范所采用或引用的有關國標、行標、文件等均為1996年1月前已發(fā)布的現(xiàn)行標準和文件。新增標準36篇，更換新標準14篇，取消原規(guī)

3、范附錄十六中序號26標準1篇。由于新標準的引用而涉及本規(guī)范的條文修改也比較多，如高強度螺栓連接，油罐安裝，焊接工藝、質(zhì)量，管道安裝，泵類安裝，整套啟動試運，化學清洗，安全閥調(diào)整，蒸汽沖洗等。由于新設備、新工藝、新材料的出現(xiàn)，本規(guī)范補充增加的新條款也較多，其中“3受熱面”中增加了“3.5循環(huán)泵”新增條款10條，在“5煙、風、煤管道及附屬設備”中增加了“5.5煙氣脫硫裝置”新增條款20條，在“7.3磨煤機”中增加了“7.3.5MPS(ZGM
