editor">　　由于水垢的產(chǎn)生傳熱會(huì)變差，使鍋爐的換熱效率降低，難以達(dá)到額定標(biāo)準(zhǔn)。而且由于傳熱不良，金屬過熱，壓力鍋爐在鍋爐內(nèi)處于壓力作用下，爐管鼓包甚至爆炸(這里不包括常壓鍋爐)；傳熱變差，使燃料消耗增加，運(yùn)行成本增加，鍋爐壽命縮短。因此，鍋爐結(jié)垢后，應(yīng)采取必要的方法去除水垢。讓我們一起了解鍋爐清洗維護(hù)的重要性。<br /> 　　一、鍋爐清洗系統(tǒng)的設(shè)計(jì)原則<br /> 　　臨時(shí)管道內(nèi)不得有砂石等雜物，水平敷設(shè)的臨時(shí)管道朝向排水方向的傾斜度不得小于1/200。管道的焊接部分應(yīng)位于觀察處。接頭不應(yīng)靠近重要設(shè)備。清洗泵的入口應(yīng)裝有小于5毫米的過濾網(wǎng)，水箱的水位應(yīng)至少高于泵的入口2米以防止氣蝕。汽包上設(shè)有臨時(shí)液位計(jì)和液位報(bào)警裝置，并在汽包的下噴嘴處增加一個(gè)25號(hào)孔板。鍋爐汽包頂部應(yīng)設(shè)置一個(gè)不少于32的氫氣排放孔。<br /> 　　二、鍋爐清洗的維護(hù)工作<br /> <p> 　　系統(tǒng)安裝后，水壓試驗(yàn)合格，儲(chǔ)水、供水充足。根據(jù)技術(shù)和安quan措施要求，準(zhǔn)備好各種藥品和實(shí)驗(yàn)室儀器，安裝監(jiān)測管，確保藥品檢驗(yàn)準(zhǔn)確。與化學(xué)清洗無關(guān)的設(shè)備和系統(tǒng)應(yīng)拆除或可靠隔離，過熱器隔離，水位計(jì)和儀表、取樣和加藥管道隔離。為了保持鍋爐清洗的溫度，應(yīng)關(guān)閉爐膛和尾部煙道出口。

　　以上就是鍋爐清洗維護(hù)的重要性。鍋爐結(jié)垢后，應(yīng)采取必要的方法去除水垢，以保證后期設(shè)備的正常運(yùn)行。<br /> 小編：Lynn<br /></div> <div id="4playbtq4cq" class="page" style="clear:both;"> 上一條： <a
