可分為自然循環(huán)、輔助循環(huán)、直流和復(fù)合循環(huán)。氣凈化和灰渣處理鍋爐氣中所含粉塵（包括飛灰和炭黑）、硫和氮的氧化物都是污染大氣的物質(zhì)，未經(jīng)凈化時其排放指標(biāo)可能達(dá)到環(huán)境保護(hù)規(guī)定指標(biāo)的幾倍到數(shù)十倍。控制這些物質(zhì)排放的措施有燃燒前處理、改進(jìn)燃燒技術(shù)、除塵、脫硫和脫硝等。借助高囪只能降低囪附近地區(qū)大氣中污染物的濃度。氣除塵所使用的作用力有重力、離心力、慣性力、附著力以及聲波、靜電等。對粗顆粒一般采用重力沉降和慣性力的分離，在較高容量下常采用離心力分離除塵。靜電除塵器和布袋過濾器具有較高的除塵效率。濕式和文氏-水膜除塵器中水滴水膜能粘附飛灰，除塵效率很高，還能吸收氣態(tài)污染物。氣脫硫有吸收法和催化氧化法。干法吸收用堿性氧化鋁、半焦炭、活性炭等；濕法吸收用氨、碳酸鈉、石灰漿等。用五氧化二釩等觸媒在一定溫度下可使大部分二氧化硫氧化為三氧化硫，從而有助于吸收脫硫。由于氣脫硫設(shè)備及運行費用昂貴，大部分企業(yè)傾向使用低硫燃料以降低硫氧化物的排放量。氣中氮氧化物主要是一氧化氮。氣脫硝有催化分解法、選擇性催化還原法，也有采用高溫活性炭吸收脫硝的。燃煤鍋爐在運行中必然要排出大量爐渣和由除塵器收集的飛灰。</p><p> 使垢渣下的金屬表面始終處于潮濕狀態(tài)，同時垢渣又妨礙氧擴散進(jìn)去，而垢渣周圍的金屬表面則有較充足的氧。這樣，由于氧的濃度差異，便形成了濃差腐蝕電池，渣垢周圍氧濃度大的部位為陰極，垢渣下氧濃度低的部位為陽極而使垢下金屬受到腐蝕。由上可知，要防止停用蒸汽發(fā)生器發(fā)生腐蝕，就應(yīng)使蒸汽發(fā)生器的金屬表面保持干燥和清潔，及時***水垢或堆積的水渣；對于濕法保護(hù)的，應(yīng)盡量降低水中的含鹽量，防止加速氧腐蝕。四、停用保養(yǎng)的基本原則1、阻止外界空氣進(jìn)入停用蒸汽發(fā)生器汽水系統(tǒng)內(nèi)；2、保持汽水系統(tǒng)內(nèi)金屬表面的干燥；3、在金屬內(nèi)表面形成具有防腐蝕作用的薄膜，以隔絕空氣；4、使金屬表面浸泡在含有除氧劑或其他保護(hù)劑的介質(zhì)中。五、停用腐蝕的防止、減輕方法為了防止或者減輕停用腐蝕，應(yīng)采用停爐保護(hù)措施。停爐保護(hù)的方法很多，主要分兩類：濕法保護(hù)和干法保護(hù)。濕法保護(hù)常用于停用時間較短的情況，例如一個月以內(nèi)。濕法保護(hù)常用的方法是將蒸汽發(fā)生器內(nèi)充滿除過氧的水，或含堿的水溶液，保持，以防止空氣漏入。如果停爐時間較長，或天氣較冷，為防止凍壞設(shè)備，應(yīng)采用干法保護(hù)。方法是停爐后，水溫降到70~80℃時，將爐水全部放掉。哈密高壓蒸汽發(fā)生器廠家。</p><div

一般用水力或機械的方法送至堆渣場。20世紀(jì)50年代以來，人們努力發(fā)展灰渣綜合利用，化害為利。如用灰渣制造水泥、磚和混凝土骨料等建筑材料。70年代起又從粉煤灰中提取空心微珠，作為耐火保溫等材料。蒸汽發(fā)生器熱平衡計算鍋爐熱效率（簡稱鍋爐效率）的方法。鍋爐熱效率是指送入鍋爐的燃料熱量中得到有效利用的百分?jǐn)?shù)。近代電站鍋爐的效率可達(dá)90%以上；工業(yè)鍋爐的效率可達(dá)75%以上。送入鍋爐的燃料熱量，除了有效利用的部分外，都以各種形式損失掉了，計有：排帶走的熱損失；排中未燃盡的一氧化碳、氫和甲烷等造成的氣體不完全燃燒熱損失；飛灰、爐渣和爐排漏煤等所含未燃盡碳造成的固體不完全燃燒熱損失和散熱損失等。為了考核性能和改進(jìn)設(shè)計，鍋爐常要經(jīng)過熱平衡試驗。直接從有效利用能量來計算鍋爐熱效率的方法叫正平衡，從各種熱損失來反算效率的方法叫反平衡?？紤]鍋爐房的實際效益時，不僅要看鍋爐熱效率，還要計及鍋爐輔機所消耗的能量。單位質(zhì)量或單位容積的燃料完全燃燒時按化學(xué)反應(yīng)方程式計算出的空氣需求量稱為理論空氣量。為了使燃料在爐膛內(nèi)有更多的機會與氧氣接觸而燃燒。實際送入爐內(nèi)的空氣量總要大于理論空氣量。阿勒泰工業(yè)蒸汽發(fā)生器多少錢</p><p
