是蒸汽動(dòng)力裝置的重要組成部分。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)。鍋爐可按照不同的方法進(jìn)行分類。鍋爐按用途可分為工業(yè)鍋爐、電站鍋爐、船用鍋爐和機(jī)車鍋爐等；按鍋爐出口壓力可分為低壓、中壓、高壓、超高壓、亞臨界壓力、超臨界壓力等鍋爐。中國電站鍋爐的現(xiàn)行系列為：中壓；高壓10兆帕；超高壓14兆帕；亞臨界壓力17兆帕。中國工業(yè)鍋爐的現(xiàn)行系列為：、、、。蒸汽發(fā)生器鍋爐按水和氣的流動(dòng)路徑可分為火筒鍋爐、火管鍋爐和水管鍋爐，其中火筒鍋爐和火管鍋爐又合稱為鍋殼鍋爐；按循環(huán)方式可分為自然循環(huán)鍋爐、輔助循環(huán)鍋爐。即強(qiáng)制循環(huán)鍋爐）、直流鍋爐和復(fù)合循環(huán)鍋爐。阿勒泰全自動(dòng)蒸汽發(fā)生器哪家好哈密冷凝蒸汽發(fā)生器廠家。</p><div

蒸汽發(fā)生器發(fā)展歷史編輯鍋爐的發(fā)展分鍋和爐兩個(gè)方面。蒸汽發(fā)生器鍋的發(fā)展18世紀(jì)上半葉，英國煤礦使用的蒸汽機(jī)，包括J.瓦特的初期蒸汽機(jī)在內(nèi)，所用的蒸汽壓力等于大氣壓力。18世紀(jì)后半葉改用高于大氣壓力的蒸汽。19世紀(jì)，常用的蒸汽壓力提高到。與此相適應(yīng)，早的蒸汽鍋爐是一個(gè)盛水的大直徑圓筒形立式鍋殼，后來改用臥式鍋殼，在鍋殼下方磚砌爐體中燒火。隨著鍋爐越做越大，為了增加受熱面積，在鍋殼中加裝火筒，在火筒前端燒火，氣從火筒后面出來，通過磚砌的道排向囪并對(duì)鍋殼的外部加熱，稱為火筒鍋爐。開始只裝一只火筒，稱為單火筒鍋爐或康尼許鍋爐；后來加到兩個(gè)火筒，稱為雙火筒鍋爐或蘭開夏鍋爐。1830年左右，在掌握了質(zhì)量鋼管的生產(chǎn)和脹管技術(shù)之后出現(xiàn)了火管鍋爐。一些火管裝在鍋殼中，構(gòu)成鍋爐的主要受熱面，火（氣）在管內(nèi)流過。在鍋殼的存水線以下裝上盡量多的火管，稱為臥式外燃回火管鍋爐。它的金屬耗量較低，但需要很大的砌體。火筒火管鍋爐，氣流出火筒后再流過火管，稱為蘇格蘭船用鍋爐。其形狀和尺寸可與輪船機(jī)艙配合較好，鍋爐本身也較輕。所以一直在船舶上使用。機(jī)車鍋爐在只有火管的鍋殼前方裝上一個(gè)包有水夾套的火箱，火箱下部裝爐排燒火，布置緊湊。克拉瑪依做豆腐蒸汽發(fā)生器多少錢。新疆微型蒸汽發(fā)生器哪家好</p><p

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?？諝鉂穸容^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。烏魯木齊防爆蒸汽發(fā)生器電話</p><p
