1防止空預(yù)器堵灰、腐蝕措施適應(yīng)范圍：空預(yù)器堵灰、腐蝕嚴重的鍋爐技術(shù)原理與要點：空預(yù)器綜合冷端溫度（空預(yù)器進口空氣溫度與煙氣出口平均溫度之和）對冷端結(jié)露和腐蝕、堵灰影響較大?？疹A(yù)器出口綜合冷端溫度如低于酸**溫度，空預(yù)器冷端很快就會積灰，一周內(nèi)就形成極難去除的板結(jié)垢。冷端溫度目標值應(yīng)根據(jù)“綜合冷端溫度與燃料含硫量變化曲線”確定，并根據(jù)燃用煤種性質(zhì)進行修正，除收到基全硫（St,ar）＜，燃用其他煤種原則上不要低于130℃。煙氣酸**主要受燃煤中的硫分、灰分、灰成分（特別是灰中Ca含量）、水分和發(fā)熱量的影響，灰分和灰中Ca含量越高，酸**越低；硫分和水分越高，酸**越高。由于不同酸**計算經(jīng)驗公式計算出的數(shù)值偏差較大，對燃用煤種相對穩(wěn)定的鍋爐，應(yīng)通過調(diào)整冷端溫度觀察空預(yù)器差壓變化趨勢等方法，確定該煤種對應(yīng)的目標綜合溫度控制值，并根據(jù)空預(yù)器煙氣側(cè)差壓變化情況及時提高空預(yù)器冷端溫度控制值。為提高控制精度和減輕運行人員調(diào)整工作量，空預(yù)器綜合冷端溫度控制目標值建議通過原煙氣SO2濃度、燃煤量、煙氣量等參數(shù)實時計算并參與自動調(diào)節(jié)。機組啟/停階段要注重冷端溫度控制。 </p><p> 高爐煤氣是冶金聯(lián)合企業(yè)主要的副產(chǎn)廢氣，經(jīng)過凈化處理，是一種輸送和使用方便、燃燒后又無需排渣和除塵的質(zhì)量環(huán)保能源，我國大部分的冶金企業(yè)都采取了煤氣回收利用措施，但隨著高爐原料條件的改善和裝備水平的提高，高爐煤氣的發(fā)熱值越來越低（大型高爐煤氣熱值已降到3140kJ/m3，中小高爐分別降到3340~3550kJ/m3和3760~3970kJ/m3），因此如何有效提高高爐風(fēng)溫成為一個重要課題。高爐熱風(fēng)爐采用空氣、煤氣雙預(yù)熱是提高風(fēng)溫的有效途徑。燃燒單一高爐煤氣（熱值3369kJ/m3），不預(yù)熱時，其理論燃燒溫度只有1280℃；只預(yù)熱空氣到250℃時，其理論燃燒溫度提高到1330℃；而空氣、煤氣雙預(yù)熱到170℃時，能提高到1380℃。u工藝：利用300℃左右的煙氣分別預(yù)熱助燃空氣、高爐煤氣至約150℃。板式空氣預(yù)熱器是一種節(jié)能設(shè)備。</p><div

本起空預(yù)器堵塞事件中B側(cè)空預(yù)器發(fā)生***氫氨堵塞嚴重，而A側(cè)較輕的原因經(jīng)檢查為：B側(cè)脫硝從鍋爐尾部煙道轉(zhuǎn)彎到脫硝入口的水平煙道處積灰明顯比A側(cè)積灰要嚴重，進一步檢查發(fā)現(xiàn)B進口在安裝時少安裝一級導(dǎo)流板，說明，B側(cè)脫硝因少裝一級導(dǎo)流板，造成煙氣中因渦流等原因形成煙道阻力加大，一方面因B側(cè)入口流場不均，易造成局部氨逃逸率增加。另一方面B側(cè)煙氣流量降低，進一步加劇流場不均。**終導(dǎo)致B側(cè)脫硝局部氨逃逸率超標幅度增加，造成B側(cè)空預(yù)器堵塞更嚴重。4結(jié)論為提高SCR脫硝工藝脫硝效率，NH3/NOx摩爾比通?？刂茷榇笥?，因此脫硝過程氨逃逸不可避免。SCR脫硝過程使用的釩基催化劑會對煙氣中的SO2產(chǎn)生催化作用，使其易被氧化為SO3。SO3與逃逸的氨反應(yīng)生成***氫氨，***氫氨附著于催化劑的表面會阻塞催化劑并影響其活性，且***氫氨的粘性使之易于牢固黏附在空預(yù)器蓄熱元件的表面，使蓄熱元件積灰，空預(yù)器流通截面減小、阻力增加以及換熱元件的換熱效率下降?？赏ㄟ^控制SCR脫硝過程氨逃逸量和煙氣中SO3的方法減少***氫氨的生成量。為防止催化劑因***氫氨的滯留而失去活性，應(yīng)合理控制SCR脫硝裝置在低負荷下的運行時間。為有效降低***氫氨在空預(yù)器換熱元件上的形成速率。板式空氣預(yù)熱器價格。河南空氣預(yù)熱器電話</p><p
