一、什么是停用腐蝕？蒸汽發(fā)生器在冷備用、熱備用或檢修期間所發(fā)生的腐蝕損壞稱為停用腐蝕。蒸汽發(fā)生器產(chǎn)生停用腐蝕，主要是因?yàn)橥t期間金屬內(nèi)表面沒有完全干燥以及大氣中的氧氣不斷漏入造成的。雖然停爐期間蒸汽發(fā)生器受熱面的內(nèi)部和外部同時(shí)發(fā)生腐蝕，但內(nèi)部腐蝕比外部腐蝕要嚴(yán)重，所以停用腐蝕主要指受熱面的內(nèi)部腐蝕。二、停用腐蝕的產(chǎn)生原因停爐以后，隨著壓力、溫度的降低，蒸汽發(fā)生器中的水蒸氣凝結(jié)成水，蒸汽發(fā)生器內(nèi)部會(huì)出現(xiàn)真空，外部空氣漏入爐內(nèi)，氧氣在有水分和水蒸氣的情況下，很容易對(duì)金屬產(chǎn)生腐蝕。由于蒸汽發(fā)生器結(jié)構(gòu)上的原因，如果不采用一定的措施，停用腐蝕是不可避免的。三、停用腐蝕的影響因素01》溫度對(duì)放水停用的蒸汽發(fā)生器，金屬表面的潮氣對(duì)腐蝕速度影響很大。空氣濕度較大時(shí)，易在金屬表面結(jié)露，形成水膜，造成腐蝕加劇。當(dāng)金屬表面干燥，且蒸汽發(fā)生器內(nèi)部的相對(duì)濕度小于30％時(shí)，可以完全防止鐵的腐蝕。02》水中的含鹽量蒸汽發(fā)生器中或金屬表面水膜中含鹽量增加會(huì)加速腐蝕進(jìn)行，特別是氧化物和***鹽含量增大時(shí)，將使腐蝕速度明顯上升。03》金屬表面的清潔程度當(dāng)金屬表面有沉積物或水渣時(shí)，該部位就易積存殘留水分。阿圖什全自動(dòng)蒸汽發(fā)生器購買烏市電蒸蒸汽發(fā)生器廠家。</p><div

蒸汽發(fā)生器，也就是蒸汽鍋爐，是蒸汽動(dòng)力裝置的重要組成部分，像燃?xì)庹羝l(fā)生器、燃油蒸汽發(fā)生器，就是燃料不同的蒸汽發(fā)生器，或者稱為蒸汽鍋爐。電站鍋爐、汽輪機(jī)和發(fā)電機(jī)是火力發(fā)電站的主機(jī)，因此電站鍋爐是生產(chǎn)電能的重要設(shè)備。工業(yè)鍋爐是在各種工業(yè)企業(yè)中提供生產(chǎn)和供暖所需的蒸汽的必不可少的設(shè)備。工業(yè)鍋爐數(shù)量甚多，需要消耗大量燃料。利用生產(chǎn)過程中高溫廢氣作為熱源的余熱鍋爐對(duì)節(jié)能有重要作用。船用鍋爐裝在各種船舶上，所產(chǎn)生的蒸汽用于驅(qū)動(dòng)蒸汽動(dòng)力機(jī)械。機(jī)車鍋爐作為蒸汽機(jī)車的主要設(shè)備尚有一定的應(yīng)用。鍋爐承受高溫高壓，安全問題十分重要。即使是小型鍋爐，一旦發(fā)生，后果也十分嚴(yán)重。因此，對(duì)鍋爐的材料選用、設(shè)計(jì)計(jì)算、制造和檢驗(yàn)等都制訂有嚴(yán)格的法規(guī)。</p><p> 燃燒器噴出的煤粉氣流在爐膛中先下降，再轉(zhuǎn)彎上升。后來又出現(xiàn)了前墻布置的旋流式燃燒器，火焰在爐膛中形成L形火炬。隨著鍋爐容量增大，旋流式燃燒器的數(shù)目也開始增加，可以布置在兩側(cè)墻，也可以布置在前后墻。1930年左右出現(xiàn)了布置在爐膛四角且大多成切圓燃燒方式的直流燃燒器。60年代某些國家曾在多角形爐膛中應(yīng)用直流燃燒器的切圓燃燒方式，用以燃燒褐煤。第二次世界大戰(zhàn)后，石油價(jià)廉，許多國家采用燃油鍋爐。燃油鍋爐的自動(dòng)化程度容易提高。70年代石油提價(jià)后，許多國家又轉(zhuǎn)向利用煤炭資源。這時(shí)電站鍋爐的容量也越來越大，要求燃燒設(shè)備不*能燃燒完全，著火穩(wěn)定，運(yùn)行可靠，低負(fù)荷性能好，還必須減少排中的污染物質(zhì)。40～60年代，為了強(qiáng)化燃燒和減少飛灰，一度采用液態(tài)排渣煤粉爐和旋風(fēng)爐，但由于采用這種燃燒方式生成的氮氧化物太多，從70年代起已較少采用。在燃煤（特別是燃褐煤）的電站鍋爐中采用分級(jí)燃燒或低溫燃燒技術(shù)，即延遲煤粉與空氣的混合或在空氣中摻氣以減慢燃燒?；虬讶紵鞣稚㈤_來爐溫，不但可氮氧化物生成，還能減少結(jié)渣。沸騰燃燒方式屬于一種低溫燃燒，除可燃用灰分十分高的固體燃料外，還可在沸騰床中摻入石灰石用以脫硫。吐魯番全自動(dòng)蒸汽發(fā)生器購買。</p><div
